Forest pansy redbud leaves in the spring

In our Ohio landscapes, we have several common options for planting trees that reach a small-to-medium size in maturity, including magnolias, crabapples, cherries and Japanese maples. Another tree that fits that size category and is commonly found in many landscapes is the eastern redbud (Cercis canadensis). Redbuds are known for their beautiful display of flowers in the early spring, typically before leaves fully emerge. But while the flowers grab our attention, the foliage could be considered fairly typical and undistinguished. One variety of redbud that can stand out for both its flowers and foliage is the forest pansy redbud (Cercis canadensis ‘Forest Pansy’)! Let's take a closer look at this tree and why it might be a great option for your landscape!

The forest pansy redbud is a cultivar (cultivated variety) of eastern redbud. Cultivars, incredibly common among many of our landscape plants from trees to shrubs to perennials, are versions of plants that are not commonly found in nature. This can be a different color of flower, variegated foliage, lack of fruit production, difference in shape or habit, or many other characteristics. In the case of the forest pansy redbud, the striking difference from the normal species is the foliage color. The forest pansy redbud’s leaves emerge in the spring with a purple to burgundy color. As summer approaches and the foliage matures, the color of the leaves can deepen to a dark reddish-purple. In autumn, as the color pigments of the foliage break down, rich yellows and golds appear and contribute to the beauty of the transitioning landscape. As with the normal species of eastern redbud, the forest pansy cultivar also has the much loved clusters of pinkish flowers that emerge directly from the stems prior to the leaves emerging in spring, giving us an early display of color when many other plants still appear to be dormant.

Forest pansy redbuds are hardy in USDA zones 5-9, making them a good choice for Ohio. They are generally tolerant of less than ideal soil conditions, but like most trees, prefer some initial amending of the soil if needed for proper soil pH, nutrients, and drainage, as well as ongoing addition of leaf compost or supplemental fertilization for optimal growth. The red pigments in the leaves will be deeper and richer with ample sunlight, so while the tree can tolerate a semi-wooded or shadier setting, substantial shade can create leaves that take on more of a green appearance (as a fun side note - this correlation between sunlight and richness of color generally applies to most plants with variegated or colored foliage!).

The forest pansy redbud is typically free of pests and diseases when properly planted and located in the landscape. It has a mature height of 20 to 25 feet and a mature crown spread of 15 to 20 feet. This makes it a good candidate for planting in front and backyards, where it can grow large enough to provide some shade to a front walkway, south facing window, or backyard patio, but stays small enough to not overtake a home or outcompete adjacent lawn areas or landscape beds for sunlight and water. Because of its striking foliage throughout the growing season, it makes a wonderful specimen tree or focal point in the landscape when planted singly, rather than in groupings.

The forest pansy redbud tree can be a great option for your landscape if you’re looking for a medium sized tree that’s tolerant of a wide range of conditions.

Fire Blight: More Than Just a Bad Sight!

By Mitch Lippencott

The Basics

Fire blight is a bacterial infection lethal to members of the Rosaceae family, which includes rose, pear, cherry, apple, serviceberry, hawthorn, and quince. While it can't be effectively cured, preventative measures have prolonged the lives of infected plants. Most importantly, disease-resistant cultivars have greatly reduced die-off rates.

What Does Fire Blight Look Like?

As the name suggests, plants affected by fire blight appear burnt. When daytime temperatures rise above 65 degrees, leaves begin to wilt, and new stems become dry and brown. Soon, whole twigs darken, and often curl into a distinctive 'shepherd's crook'.

 Fruits turn black, and are “mummified” in place. Eventually, entire branches canker and ooze. At this point, the bacteria has spread to all parts of the tree, including the root system. There are fungal pathogens and weather-related injuries with similar visuals, so tissue samples should be sent to a lab before conducting treatment.

Where Does It Come From?

Erwinia amylovora, the bacterial strain causing fire blight symptoms, can be spread by air, water, and insect and human activity. It can enter a host plant in several ways. When flowers begin to open, air and waterborne strains find their way in to the flower's reproductive organs. As pollinators visit infected flowers, they spread the bacteria to uninfected flowers. Unsealed pruning cuts, broken branches, and even holes made by sucking insects, like aphids, are other paths into the tree. As the disease progresses to the point of bark canker, the cankers themselves are entry points, and the ooze seeping out of them attracts additional insect spreaders.

Humans distribute the bacteria when they cut or move affected wood, fruit, or leaves - just as germs linger on door handles, fire blight remains alive and mobile on all living tissue and the tools used to handle it. Deer and other herbivores further distribute fire blight by feeding.

Wilted leaves with a burnt color is a symptom of fire blight.

How Bad is It?

Bad. It spreads rapidly, mutates easily, and is almost always fatal. Young infected trees can die in a single season. Healthy, established trees being managed can hang on for many years, but still typically die because of the infection. While resistant cultivars have largely eliminated the death of entire properties, even today, infected plants are almost always in the express-lane to removal.

Can It Be Treated?

Not well. The only highly effective defense is planting cultivars resistant to infection. At this time, all pear and quince cultivars are somewhat susceptible. The popular apple cultivars Fuji, Honeycrisp, and Red Delicious show strong resistance to fire blight. For crabapples, 'Prairiefire', and 'Golden Raindrops' are highly resistant, while 'Autumn Brilliance' is a resistant serviceberry tree. No popular flowering cherry varieties are at high risk.

Branches infected by fire blight should be cautiously removed. Tools must be disinfected afterwards.

The second-best protection is proper cultural practices. Fire blight thrives in moisture and humidity, so plants in full sun with good airflow and well draining soil are less prone to infection. Proper irrigation is critical. Branches displaying fire blight symptoms should be cautiously removed.

Cuts must be made at least 10 inches below the first visibly infected branch portion. Tools must be disinfected with isopropyl alcohol or bleach solutions after every cut. Cut material must be collected and discarded properly. Pruning healthy tissue for clearance or fruit production should be kept to a minimum and cuts should be kept as small as possible. High-nitrogen fertilizers, like those used on turf, should be avoided to encourage cut wounds to seal over, rather than sprout.    

 Are There Chemical Controls?

There are many, but none are particularly good. The lowest-level chemical intervention is repeated spray applications of neem or horticultural oil during flowering. The viscous oils have shown slight improvements in infection resistance by clogging the openings airborne bacteria use to enter flower sex organs. They may only be used preventatively on healthy trees and can onlytreat as high as the applicator's spray system allows.

Leaves infected by fire blight

Repeated antibiotic spray applications in early spring are a slightly more effective option. They can be used preventatively, and to delay spread in already diseased trees. Unfortunately, applying these chemicals multiple times is often more expensive than replacement.. Worse, the erwiniaamylovora bacteria can develop resistance rapidly unless many different chemicals are cycled, driving up costs further. In my professional experience, the only somewhat effective chemical control is a trunk-injectedantibiotic. This once-each-spring application is also expensive, but may stave off the advance of infection for 5+ years.

 Conclusion

While still deadly to susceptible hosts, the development of fire blight resistant cultivars has greatly reduced the rate of loss of some our favorite ornamental and fruit tree species. Planting in appropriate locations and improving pruning and irrigation practices are more effective and far cheaper than chemical controls. Submitting samples to a plant diagnostic laboratory is the only true way to confirm a fire blight infection.

The 5 Steps to Become an ISA Certified Arborist®!

By Enrique Arayata
ISA Certified Arborist® OH-7252A
February 27, 2025

Have you ever wondered how to become an ISA Certified Arborist®? To first answer this question, it’s probably good to know what an arborist is and what the acronym ISA means. An arborist is a professional who practices arboriculture and the study, management, and cultivation of trees, shrubs, and other woody plants. ISA is the International Society of Arboriculture, a non-profit organization that serves the tree care industry by promoting the professional, proper practice of arboriculture, developing arborists’ skills and expertise, and educating the public about trees, their benefits, and how to properly care for them. ISA offers multiple credentials, one of which is the ISA Certified Arborist® credential. ISA certifies that these arborists have a minimum of 3 years’ full-time experience in tree care and that they have passed the 200-question arboriculture exam focusing on 10 different categories of trees and tree work. Obtaining the ISA Certified Arborist® credential is a strong indication that an arborist is dedicated, knowledgeable, experienced, and caring when it comes to trees. To become an ISA Certified Arborist®, there are 5 general steps! 

1. DEVELOP AN INTEREST IN ARBORICULTURE 

Planting trees at our office!

The first step to becoming an ISA Certified Arborist® is to develop an interest in arboriculture such as tree species, tree identification, growing habits, tree structure, planting sites, diseases, pests, soil science, tree planting, tree preservation strategies, tree removal techniques, plant healthcare, working with trees around construction, tree risk assessment, safe practices, urban forestry, and so much more!  

2. HAVE 3 YEARS OF FULL-TIME ARBORICULTURAL EXPERIENCE 

ISA requires that testing candidates have a minimum of 3 full-time years of arboricultural work experience, formal education, or a combination of both. One example could be finishing your junior year of college at a university majoring in forestry or horticulture. Another example could be working for a tree care company for 3 years as a ground worker, climber, crew leader, plant healthcare technician, or sales manager. Other rapid-fire examples of practical arboricultural experience could be working at a nursery, landscape company, municipality, state forestry agency, utility company, an academic arboriculture department or extension program, a tree consultancy, or pest control provider. Regardless, documentation of experience with related references is required for verification. 

 3. STUDY FOR THE EXAM 

A very common guide that people use when studying for their ISA certification!

Now it’s time to study for the ISA Certified Arborist® Exam! Even though ISA requires applicants to have a minimum of 3 years of full-time arboriculture experience/education, you can study in the meantime so that you’re ready to take the exam as soon as you have 3 years under your belt. In terms of what to study, ISA recommends the 4th Edition Arborists’ Certification Study Guide. This is what I and almost everyone at Russell Tree Experts used. ISA has a practice exam on their website set up in the exact same fashion as the actual exam. There are also free resources online such as lessons on YouTube, Quizlet flashcards, and sample questions online. On Facebook, there are various groups pertaining to the ISA Certified Arborist® exam where you can ask questions, study together, and learn from one another! One other resource is the Certified Arborist Review sessions at the Ohio Tree Care Conference. There is an approximate 1-hour session for each of the 16 chapters in the study guide led by different ISA Certified Arborists® that I found incredibly beneficial! 

Duration of study is different for everyone. I know coworkers who read the book in less than a month and passed the test on the first try, but I also know coworkers who periodically studied over the course of 3 years and then passed the test as soon as they were eligible to apply. Personally, I studied approximately 1 page per day throughout 2024 since the study guide is 369 pages long, reviewed all of January 2025, and then took the test in February! 

 4. APPLY FOR AND SCHEDULE THE EXAM 

Once you are eligible and feel confident in your studies, it’s now time to apply for and schedule the ISA Certified Arborist® exam! First, you’ll want to visit ISA’s website, create an account, and then become a member of your local chapter. Central Ohio’s local chapter is Ohio Chapter ISA. Afterwards, apply for testing eligibility. This is when ISA will ask for documentation of 3 years’ work or educational experience in arboriculture. Once you’re approved, you can schedule your exam. 

Ohio Chapter ISA: Ohio’s local ISA chapter.

For the exam, you can choose between a computer-based exam or a paper-based exam. Both require you to drive to a proctored exam site. Both exams are in the same format, cover the same topics, and are at the same difficulty level. Advantages of the computer-based exam is that there are more testing sites, potentially resulting in a shorter drive in most cases, being able to know your results immediately compared to waiting up to 6 weeks to know the results of a paper-based exam, and to save time clicking your answer as opposed to filling in 200 bubbles on a scantron with the paper-based exam. Two potential downsides of a computer-based exam are that it is costlier than the paper-based exam due to a $125 administrative fee and it is a little more tedious to click back-and-forth between questions compared to flipping the physical exam book pages. Advantages of the paper-based exam are if the testing site is closer to you than the computer-based exam testing site, being able to physically flip back-and-forth more quickly between questions, and having something physical and not digital to look at for 3.5 hours in case eye strain is a concern. 

Regardless of which exam you choose, you will need to select the specific testing date and location, submit an application to take the test, and then receive approval before you are officially enrolled. At the time of writing this ARBOR ED™ article, the exam fee ranges from $170 to $405 depending on your membership status and which testing option you choose. 

 5. TAKE THE EXAM 

Now it’s time to take the exam! The ISA Certified Arborist® exam comprises of 200 multiple-choice questions. Each question has 4 possible answers. There are no “all of the above” answer options, no multiple correct answers, and no images throughout the entire exam. There are 3.5 hours allotted to complete the exam. In order to pass, a 76% or higher is required. The exam content material is divided into 10 domains of knowledge: 

1. Tree Biology (11%) 

2. Identification and Selection (9%) 

3. Soil Management (7%) 

4. Installation and Establishment (9%) 

5. Pruning (14%) 

6. Diagnosis and Treatment (9%) 

7. Trees and Construction (9%) 

8. Tree Risk (11%) 

9. Safe Work Practices (15%) 

10. Urban Forestry (6%) 

From personal experience and chatting with multiple coworkers, 3.5 hours is plenty of time to take the exam. One tip is that some questions can provide context clues that can help answer a different question in the exam, so do not feel discouraged to skip a question and come back to it later. There should be at least 30 to 60 additional minutes to revisit unanswered questions or review unsure questions.  

MAINTAINING YOUR ISA CERTIFIED ARBORIST® CREDENTIAL

6 Harmful Pruning Methods for Trees

By Enrique Arayata

ISA Certified Arborist® OH-7252A
February 4th, 2025

Tree pruning is the selective removal of branches, buds, and roots from a tree. Pruning is a common and necessary form of tree maintenance that can be beneficial or detrimental to a tree’s health depending on the location and quantity of the cuts. Poor pruning practices will decrease the health and vigor of a tree and increase the likelihood of structural failure or even worse, tree death. More specifically, improper tree pruning can lead to unaesthetic appearances, stunted growth, insect and disease susceptibility, compromised structure, poor branching habits, decayed and damaged limbs, and property damage due to limb failure. On the flip side, proper pruning practices can increase a tree’s aesthetics, health, and longevity, allowing it to be a beautiful sight for sore eyes instead of a headache for the owner. 

The goal for this ARBOR ED™ article is to learn more about improper pruning practices, some of which are contextual and situational depending on the timing, quantity, or location of the pruning cut, and to have you identify if your tree has been improperly pruned! To learn more about the benefits and use cases of tree pruning, read here for my previous ARBOR ED™ article on the importance of tree pruning! 

An example of tree topping.

1. TREE PRUNING

One of the most harmful pruning mistakes is tree topping. Tree topping is the removal of entire top-ends of tree stems, sometimes including the central leader, regardless of the stem’s health. Often times, healthy stems with plenty of green leaves are removed during tree topping. The thought behind this is to increase light visibility for grass or plants below the tree, to control a tree’s size, and/or to shape a tree to the owner’s liking. However, tree topping can have serious long-term consequences. Tree topping looks aesthetically unpleasing due to many leaves and greenery being removed from the tree. When topping a mature tree, the topped stem could be large enough to where it is difficult for the tree to properly compartmentalize and close the wound, which is basically an open-door invitation for insect and disease issues. Compartmentalization in layman’s terms is how a tree heals, closes, and recovers from a wound. When large branches are removed, trees will respond by growing small, skinny shoots known as watersprouts that are poorly attached to the trunk. These shoots often grow on the interior of a tree in an upright behavior. They are often weakly attached to the tree and are prone to breakage if they mature large enough. This poses a structural, safety risk for nearby items like concrete, houses, cars, and more. With the removal of much of the tree's canopy, this will reduce its ability to photosynthesize and produce energy. The tree may experience severe stress, making the tree more prone to insect and disease issues. 

An example of lion tailing.

2. LION TAILING

Lion tailing is the removal of a majority of the interior or lower branches of a tree stem or an entire tree. This leaves foliage clustered at a branch’s end, similar to the appearance of a lion’s tail. Lion tailing often occurs due to improper pruning practices like tree thinning and general over pruning. This type of tree pruning can often result in weakened branch structure or load failure, causing the limb to break. Two additional consequences of lion tailing are the production of watersprouts and an increased risk of sunburned bark tissue. Lastly, lion tailed trees have less leaves for photosynthesis and will often result in general stress due to a nutrient deficiency.  

A subtle example of excessive pruning. Note the small amount of interior branches that is uncharacteristic of honeylocust trees.

3. EXCESSIVE PRUNING

Another common tree care mistake is excessive tree pruning, which occurs when too many branches are removed in one session, or when a tree is over-pruned over a small range of time. While it might seem like pruning a tree heavily will promote its health, in reality, it often does more harm than good. Pruning removes leaves, and leaves are the primary site for photosynthesis. Without enough leaves, a tree struggles to produce the energy it needs to thrive. This leaves it more susceptible to pests, diseases, and environmental stresses like sun scorch and drought. Over-pruned trees are often stunted in growth and will develop the same watersprouts mentioned earlier. The exact amount of pruning for a tree is often debated because there is no definitive answer. The general rule of thumb is to identify the purpose of pruning a tree and to prune as little as necessary to achieve the desired outcome. Common reasons to prune a tree are to reduce risk, improve or restore structure, provide clearance, manage crown size, or to remove dead or diseased limbs. If the reason for pruning can be accomplished with just a few pruning cuts, then there is no need to over prune. 

4. INCORRECT PRUNING CUTS AND LOCATIONS

There are many ways that a specific, individual pruning cut can be incorrect and harmful to a tree, so much so that a short book could be written. As a brief, condensed overview, a cut can be improper if it is at an unideal location on a stem or if it was performed using an improper tool. Using a dull or rusty tool can lead to improper cuts that the tree cannot compartmentalize properly. A proper, finished cut should have a smooth surface without jagged edges or torn bark. These defects could create a vulnerable location for insect or disease problems.  

Choosing the right pruning tool is important. Most folks would not use a chainsaw to prune a bonsai tree. Trust me, I’ve tried, and it didn’t work out well (for me or the bonsai tree). Jokes aside, there are often gray areas where limbs could be pruned with smaller tools such as loppers or pruning shears, but a handsaw or chainsaw would be more effective and leave a cleaner cut. 

Even if a clean pruning cut has been made, it could be at the wrong location and cause increased compartmentalization time, leaving the tree exposed to potential insect or disease problems for a longer period of time. A pruning cut should be made just outside the branch bark ridge and branch collar. The branch collar is the swollen area around the underside/base of a tree branch where it meets the trunk of a tree. The branch bark ridge is a raised strip of bark above a branch union that forms as a result of the trunk and stem connecting, thus pushing the bark into a ridge. Together, the branch bark ridge and branch collar have special tissues that assist in a tree’s compartmentalization response to a pruning wound and to defend that wound from infection. It is important not to damage either of these when making a pruning cut.

5. INSECT AND DISEASE PROBLEMS

Pruning is an excellent maintenance technique to minimize the risk of insect and disease problems for a tree. If you just have a couple of small limbs with decay or unwanted insect pests, they can simply be pruned off. When it comes to an entire tree suffering from a disease or infested with a pest, it is best to have it inspected by an ISA Certified Arborist® to determine the best course of action. Timing is important when it comes to preventing disease and insect pests. There are many tree species with known pest or disease issues that can be minimized through proper pruning at a certain time of year. Two important examples in central Ohio are the pruning of oak and elm trees between October 15th and March 31st to minimize the risk of oak wilt and Dutch elm disease. 

6. UNIDEAL TIMING

Timing, both frequency and time of year, are important when it comes to tree pruning. Pruning at an improper time of the year can result in stress and stunted growth. A good, general rule of thumb to maximize growth is to prune a tree just before buds begin to swell, typically around late winter/early spring. Oppositely, pruning a tree around late spring or early summer could cause a tree to grow a little slower, which could be beneficial in an urban or tightly spaced setting. Some trees in temperate settings are best pruned during the active growing season in the middle of spring and summer to maximize the speed of wound closure. Pruning during drought-like conditions such as an unusually hot and dry August should be minimized as a tree is less likely to compartmentalize the wound quickly, potentially leading to decay. An ISA Certified Arborist® working in their local area will be familiar with common, native trees and their preferred pruning window.

Proper tree pruning is a delicate balance between art and science. While pruning may be done to improve a tree’s aesthetics, it is important to prioritize its health over its looks as a dead tree is an unaesthetic tree. If possible, avoid any and all of the improper pruning mistakes mentioned in this article such as tree topping, lion tailing, excessive pruning, improper cuts, and incorrect timing to ensure that your trees remain healthy and beautiful!

How to Protect Trees Before, During, & After Heavy Construction!

By Cody Gray
January 23, 2025

What is soil compaction and how can this affect the trees growing on your property? In this article we are going to cover the “do’s” and “don’ts” during the construction process to avoid soil compaction on the property. We’ll also be peeking into soil science as well as ways to regain healthy soil composition.  

Soil compaction is caused when soil particles are pressed together, reducing pore space. Think of this like making a snowball - as you take a scoop of snow and press it together, it becomes hard and dense. The previously light and fluffy snow is now firm and sheds water. The same phenomenon is true with soil. As these particles are pressed together, air and water become scarce. With reduced pore space, water infiltration is much slower, and drainage becomes increasingly poor and insufficient. In addition to the soil’s inability to move and drain water, the exchange of gases is slowed down significantly. In poorly drained soils, the composition can turn hard and arid, causing a tree’s penetrating roots to struggle in seeking water.  

Compacted Soil

Porous Soil

Wooded lots offer extremely beautiful home sites. However, if approached improperly from start to finish, what could have been a serene place to kick your feet up at the end of a long day can slowly turn into a hazardous environment full of dead and declining trees. It’s no secret that heavy equipment is used to clear plots of land for both residential and commercial purposes. These pieces of equipment are often heavy and can cause substantial damage to the soil composition when extra care is not taken. However, there are ways to protect the trees you desire to keep if you are aware of some basic tree biology. In terms of spread, a tree’s roots mostly occupy the canopy drip line of a tree. The canopy drip line of a tree is the outermost circumference of the tree’s canopy in relation to the ground. A tree’s roots occupy this entire area and often extend two to four times the radius of the drip line. In terms of depth, most tree roots can be found in the first six to twenty-four inches of soil. This is important to know because this is where long-term root damage can occur if proper preventative measures are not taken. 

A video example of a land clearing project for a new construction home. Heavy equipment was used and soil was likely compacted.

When selecting the building site, it is important to choose an area as far away from the preserved trees as possible. However, at times this may not be possible due to the lot layout, construction needs, etc. There are ways to improve the likelihood of saving these trees inside of the construction zone. Setting up a tree protection zone can be accomplished by protecting the drip edge of the tree you plan to save. The idea is to minimize or prevent any travel of heavy equipment over this area to protect the tree’s valuable roots. One of the most effective ways to protect this precious area is by using T-posts, zip ties and a few rolls of orange barrier fence often referred to as a “snow fence”. The first step in this process is to walk out and mark the approximate drip edge of the tree. You can use orange marking paint on the ground if this helps. Next you will need to drive a T-post every four to five feet around the circumference of the drip line. Once you have traced the entire drip line of the tree, you will begin stringing your orange barrier fence and zip-tying it to your T-posts. This process is simple yet effective for keeping people as well as machines away from the root zone. Additionally, this will help limit the potential for damage to the trunk of the tree. If access is an issue and you are unable to successfully barricade the drip edge of the tree, another option is to use some sort of matting. This can be done with many different products. The simplest form of matting is plywood but whatever solution you use, this significantly reduces ground pressure, which reduces the effects of soil compaction.  

Tree Protection Zone!

Following the construction process, it is important to do a final walkthrough to determine if the grade has been changed. Any excess fill that may have been added inside of a tree’s canopy drip line should be minimized or avoided completely. A very small amount of fill used to fill in tiny divots or to lightly level the lawn is okay and unlikely to cause serious damage. A significant amount of excess fill or grade change can cause reduced oxygen and water infiltration for a tree's roots. A tell-tale sign is soil buildup around the root flare of the tree trunk. You can also take before-and-after photos and compare. If excess soil is present, it is important to remove it as soon as possible. The effects of soil compaction are not immediately noticed and often take months or years before it becomes apparent that something may be wrong. Unfortunately, by the time you notice that a tree is in decline, it is likely too late. Some key characteristics to look for include loss of leaves and premature leaf discoloration during the summer months as well as dead and decaying branches. It is not uncommon for one of our ISA Certified Arborists® to inspect a property containing a declining tree due to construction or renovation that occurred months or years in the past. Oftentimes this is discovered through a quick conversation with the property owner or when observing soil that is either compacted or covering a tree trunk’s root flare. 

There are ways to improve soil composition following compaction if it is caught quickly. One of the most effective ways is by using an air-spade. An air spade is a tool that uses compressed air to loosen the soil around the tree’s roots. An arborist will push the tool into the ground around the tree’s root system and force air into the compressed soil, causing the pore space to increase. This is a non-invasive way to expose the roots to much needed water, oxygen, and nutrients. Another simple yet effective way to help with previous soil compaction is to mulch a tree. Removing 2 to 4 inches below ground level and backfilling with porous mulch can minimize the impact of soil compaction. There are also many benefits to mulching beyond just increased pore space.

In conclusion, remember to pick a building site that requires as little tree removal as possible. If there is a tree that is in question, it is much easier to remove the tree prior to construction and it will often cost less to do so. Complete a walkthrough with your contractors, express your concerns for the trees you plan on saving, and be certain to create your tree protection zone(s). This will take a little time in the beginning of the project but can end up saving thousands of dollars over the years to come. If you follow these steps and still end up with some soil compaction, don’t fret as there are still options. Reach out to your local arborists and inquire about air spading, tree mulch ring installations, frequent watering, or other plant healthcare options that might be recommended after an inspection. I can assure you that if you take the time in the early stages of the land clearing and construction process, the survival rate of your trees will increase significantly.

It’s Easy as G-D-D (Growing Degree Days)

By Lindsey Rice
ISA Certified Arborist® OH-6739A
January 9, 2025

If you are a client of Russell Tree Experts and have us care for your trees, you’ve likely heard us use the term “growing degree day” or GDD. The concept of a growing degree day is basically how many units of heat have been accumulated within a 24-hour period. Any day with a mean temperature (average of the maximum and minimum temperature) over the “threshold temperature” of 50 degrees, growing degree days are accumulated. A threshold temperature is a temperature at which a specific plant or insect can progress in its development or life cycle. Different organisms have different base temperatures; however, 50 degrees Fahrenheit is considered acceptable for all plants and insects.

Calculating growing degree days can be complex to varying degrees. The simplest method is to subtract the base temperature from the mean temperature for the day and then add it to the previous day's growing degree day total.

Example:

It is April 11th. The average temperature is 61 degrees. Yesterday, the running total of GDD was 214. Subtracting the base temperature of 50 from the mean temperature of 61 degrees, we would arrive at 11 degrees. We would add that to yesterday's running total (214+11), and today’s current GDD is 225.

~

What information can we learn from knowing the growing degree day? Plant experts and entomologists have observed that the accumulation of heat causes development to proceed. For any given insect, its eggs will hatch, or an adult will emerge at precisely the same growing degree day every year. The date can vary from year to year since the temperature is not the same every day of the year. Below is a graphic of the growing degree day on the same date, April 11th, for the past fourteen years.

(https://weather.cfaes.osu.edu/gdd/summary.asp):  

Since we know that plants and insects do the same thing on the same approximate GDD every year (not necessarily on the same date), we also know when to apply certain treatments for optimal effectiveness. Additionally, we can use plants as a “phenological indicator” to understand when certain insects will be active. Using our example of April 11th and GDD of 225, Serviceberry (GDD 219) and Common Chokecherry (GDD 221) should both be in full bloom. Various adult leafminers will also be emerging around this time (birch leafminer – GDD 215, elm leafminer – GDD 219, alder leafminer – GDD 224).

Some people have even taken it further and planted phenological gardens! Farmers have used this practice for centuries to know when to plant certain crops and vegetables and when to look for specific pests. Here are a few rules of thumb:

• Plant potatoes when the first dandelion blooms

• Plant peas when forsythia blooms

• Plant radishes and spinach when crocus is in bloom

• Plant carrots and beets when daffodils bloom

• Plant bush beans when apple trees bloom

• Plant annual flowers and squashes when lilacs are in full bloom

These were developed as a way of measuring growing degree days before the formal calculation of growing degree days existed, but they achieved similar results.

Entomologists work hard daily to figure out the growing degree day of certain active insects and pests to improve “best practices” observed in horticulture and arboriculture. One insect we are watching closely is the nitidulid beetle. These beetles have been known to carry a fungus that causes oak wilt, a deadly fungal disease of oak trees. As we learn more about these beetles, we can implement more effective management practices to ensure the safety of everyone’s oak trees! For now, we go off of the best information available to us. You can learn more how Russell Tree Experts handles oak wilt by reading here!

Call OUPS So You Don't... Oops!!

By Joe Gabrielse
December 19, 2024

Are you about to start digging in your yard for a project such as to plant a tree or to grind out a tree stump? Before you begin, it's vital to prioritize safety by taking the necessary precautions to protect yourself and underground utility lines. One key step you should never overlook is calling the Ohio Utilities Protection Service, commonly known as OUPS. 

An example of a gas line marked in yellow.

811 is the national hotline for "Call Before You Dig," allowing homeowners and professionals to request free marking of underground utility lines. By calling 811 prior to digging, you can prevent accidental damage to vital utility lines like gas, electric, water, sewage, and telecommunications. Examples of digging projects where you can benefit from calling OUPS are planting a tree, grinding a stump, digging a new flower bed, putting in a new shed, laying a new driveway, installing a post for a new mailbox, building a retaining wall, and more. If you are utilizing Russell Tree Experts to care for your trees and digging is required such as in the case of stump grinding, we will take care of this process for you and call OUPS ahead of time!

Upon dialing 811, you will be connected to a local center. A representative will gather details about your digging project, such as location and depth of excavation. The center will then inform relevant utility companies who will then dispatch technicians to mark their underground lines with flags, paint, or both. In some cases, you will also receive an email with a summary containing a birds-eye view of the property with color coded markers as to where any lines may be located.

Advantages of Contacting 811 Before Digging

The blue oval indicates the location of a gas line that we need to be extra precautious around.

There are numerous benefits to calling 811 before digging, such as the following:

1. Compliance with Regulations. Many states mandate calling 811 to prevent harm to underground infrastructure.

2. Peace of Mind. Taking necessary safety precautions can provide peace of mind throughout your digging project and minimize the chances of stress and headaches.

3. Financial Savings. Preventing damage to utility lines can save you from costly repair expenses.

4. Enhanced Safety. Marking utility lines helps prevent potentially hazardous incidents.

Depending on the particular tree, a stump could be ground anywhere from approximately 4 to 16 inches below ground level.

Proceeding with digging without calling 811 can lead to severe outcomes. Accidentally striking a buried utility line can disrupt your project and result in headaches, expensive repairs, injuries, or even fatalities. Avoiding these dangers is as straightforward as dialing 811 before you commence digging. It’s free! 

One detail to be cautious of is that privately installed lines or pipes might not be reported to OUPS, therefore leading to those lines being left unmarked. It would be up to you to mark or be made aware of to prevent damage to said unmarked lines. Examples of unmarked lines could be an electrical line to an exterior light post, irrigation lines, and invisible dog fences.

At Russell Tree Experts, we utilize OUPS quite literally every single day. Whenever a customer requests stump grinding services, our stump grinders call OUPS a few days ahead of time so that way our machines can focus on the stump and avoid damaging any lines. 

Russell Tree Experts offers stump grinding services. Before any stump is ground, we call OUPS to mark any nearby lines that could pose an issue.

For larger tree work projects such as on federal and state property or along highways and powerlines, we contact OUPS to request any and all lines to be marked. Whenever we are using heavier equipment such as CMIs, ASVs, or Bobcats, we are sometimes asked to provide specifications such as gross vehicle weight, track width, lengths of tracks on the ground, and distance between tracks to ensure that there is no risk of damage to underground lines even during movement of our machines. Some pipes and lines can be located 18 to 24 inches below ground level. With a machine that weighs 85,000 pounds, even just driving 2 feet above the line’s location could cause damage. If the pipe is unavoidable and a piece of equipment must cross its location, we build an “air bridge” using timber mats to cross the line safely and to eliminate the risk of damage. When a line is avoidable and no tree work or equipment needs to occur nearby, we still like to have the line marked and we will set a minimum approach distance such as 50 feet so that way our crew members know not to come anywhere close to the line’s location.

A balled-and-burlapped tree can require a lot of digging in order for it to be properly planted.

The examples above may not be relatable to you from day-to-day on your private property, but tree planting can! According to the Arborists’ Certification Study Guide, a saucer shaped planting hole two to three times the width of the root ball is recommended for optimal tree planting. The depth of said hole is going to be approximately the height of the root ball, which could be upwards of two to three feet tall for a large balled-and-burlapped tree. This area is definitely deep and wide enough to where the risk of damaging a line could be high. A simple and free 811 call to OUPS could provide you the peace of mind of planting your tree with no risk (not including privately unmarked lines)!

In conclusion, calling 811 before digging is a simple yet critical measure to ensure the safety of your excavation work. Making this call can help prevent accidents, legal complications, and unnecessary expenses. Remember that safety is paramount, so don't forget to contact 811 before picking up that shovel. Be safe and happy digging!

The Sugar Maple

By Chris Gill
ISA Certified Arborist®
December 12, 2024​

The sugar maple tree (Acer saccharum) is one of my favorite trees and a beloved symbol of North American forests, renowned for its beauty and many uses. It is native across southern Canada, the midwest, and the northeastern US states. Known for its vibrant autumn colors, sweet sap, and high-quality timber, the sugar maple plays an essential role in the natural landscape, urban forest, economy, and cultural heritage of the northeastern United States.

The sugar maple tree grows best in hardiness zones 3 through 8. It has a slow-to-medium growth speed and will grow to a mature height of 60 to 75 feet with a mature width of 40 to 50 feet. Sugar maple trees grow well in well-drained soil and in partial sun, but will perform best in full sun conditions.

The sugar maple is one of the most visually captivating trees, especially during the fall when its leaves turn to brilliant shades of red, orange, and gold. Each autumn, forests, yards, and parks where sugar maples grow become vibrant canvases of color. Beyond its autumn display, the sugar maple brings beauty throughout the year. In spring, delicate clusters of yellow-green flowers bloom, signaling the arrival of warmer weather. By summer, the tree’s broad canopy offers cool, welcoming shade, making it a favorite in parks along streets and in backyards. Even in winter, when its branches are bare, the sugar maple’s ovular architecture is a beautiful sight.

The sugar maples in my backyard are a constant source of joy to my family and me; my kids often collect the autumn leaves and we all appreciate the cool shade it provides during hot summer afternoons where we play with our dog.

The sugar maple’s value extends far beyond its visual appeal. It is also a tree of exceptional utility, benefiting industries and ecosystems. The sugar maple is the lifeblood of the maple syrup industry, which is both economically and culturally significant. In early spring, when temperatures fluctuate between freezing at night and above freezing during the day, sap begins to flow within the tree. This sap is collected through taps and boiled down to produce pure maple syrup. It takes about 40 gallons of sap to produce just one gallon of syrup, making the process both labor-intensive and rewarding. Sharing the resulting syrup with my family is a tradition whether drizzled on pancakes or used to sweeten a good recipe. I like to mix two tablespoons of maple syrup with a teaspoon of dijon mustard, ¼ teaspoon of dried thyme, and 1 clove of garlic, minced, for an excellent glaze on chicken or ham.

Sugar maple is also valuable for its timber. Known as "hard maple," its wood is highly durable with a dense grain that makes it resistant to wear. This strength makes sugar maple wood a popular choice for furniture, cabinetry, and flooring. It is especially favored for high-traffic areas such as gymnasiums and basketball courts where durability is crucial.

In addition to its strength, sugar maple wood is renowned for its beauty. Patterns like "curly" and "birdseye" maple — unique grain formations that resemble ripples or tiny eyes — are highly sought after by woodworkers. Musical instruments including violins, guitars, and pianos, are often crafted from maple wood due to its aesthetic appeal and due to the wood’s density enhancing sound quality.

Birdseye Maple Wood Pattern

Curly Maple Wood Pattern

The sugar maple also contributes to the health of ecosystems in numerous ways. Its dense canopy provides shelter for birds, mammals, and insects, while its seeds and buds serve as food for creatures such as squirrels and deer. In autumn, when the tree drops its leaves, the organic matter enriches the soil, promoting healthy plant growth.

Note the fall foliage containing greens, reds, oranges, and yellows!

The tree also plays a critical role in water regulation as its roots absorb rainfall and reduce runoff, helping to prevent flooding. Forests dominated by sugar maple trees stabilize soil and prevent erosion, especially on slopes and riverbanks. The tree’s ability to thrive in well-drained, fertile soils makes it a reliable indicator of a healthy forest.

While sugar maple is a great tree for aesthetics and practicality, it is now facing significant threats due to changing weather patterns and climate shifts. The species thrives in cool climates with predictable seasons and the recent shift in temperatures, along with changes in precipitation, is making it harder for sugar maple trees to survive and reproduce in many areas. Sugar maple trees require cold winters to produce sap. The ideal conditions for sap flow — freezing nights followed by warmer days — are becoming less consistent as winters grow shorter and warmer. Without these precise temperature swings, sap production is also decreasing, directly impacting the maple syrup industry. 

Rising temperatures are also forcing the sugar maple’s growing range to shift northward. Areas that were once ideal habitats for the tree are becoming too warm or dry, while colder regions farther north are now better suited to support new growth. This gradual shift threatens the cultural and economic identity of communities that have long relied on sugar maple forests. Scientists predict that if current trends continue, sugar maple trees may disappear from parts of their southern range, such as Ohio, Pennsylvania and New Jersey, within the next century.

Additionally, the increase in frequency and intensity of droughts have been particularly damaging to sugar maple. While the tree prefers moist, well-drained soils, extended periods of drought weaken its root system and make it more susceptible to pests and diseases. Invasive pests like the Asian longhorned beetle and certain fungi have expanded their range into sugar maple forests. These pests can cause severe damage (and often tree death), weakening the trees and making them more vulnerable to environmental stresses. Fortunately, the Asian longhorned beetle has not been found in central Ohio, highlighting the importance of maintaining strict quarantine zones and monitoring programs. Preventing its spread is crucial to protecting the region’s sugar maples (as well as several additional native genera) and the ecosystems and industries they support.

Russell Tree Experts offers a range of tree services to help preserve your sugar maple trees, including health assessments to identify stress factors, pest and disease management to help mitigate threats, and soil care programs to improve root resilience. With expert pruning, deep-root fertilization, and a detailed plan, we can attempt to mitigate these challenges.

Cabling for Safer and Longer Living Trees

By Harry Carter
ISA Certified Arborist®
November 26, 2024​

As an ISA Certified Arborist® and avid tree climber, I find myself in many different trees and looking down over elegant landscapes, playgrounds and houses. I work in many trees requested to be removed by their owners due to concerns regarding potential tree failure and property damage. Although some of these trees may have defects such as poor branching habits, cracks, codominant stems, and more, there are tree preservation solutions that can work to keep them upright, healthy, and stable! Proper tree care including tree cabling can go a long way toward maintaining your big, green giant!

Trees are such a beneficial part of your property whether it’s the shade the canopies can provide to your home or the aesthetics of the wind blowing through their leaves. Unfortunately like everything else, these beautiful organisms can have their problems, especially as they mature and grow larger. These giants need some help to stick around just like me and you. Defects left unattended such as included bark or wounds can create weakened unions in your tree. Luckily, there are solutions to help keep your canopy stable! Cabling the tree creates strength from above to protect the tree and provide it with a long-term health plan to keep it together. Paired with a good pruning regimen and tree wellness prescription, we can help to keep the tree happy and healthy. Russell Tree Experts offers two types of cable systems that each have their own supportive benefits! 

Tree Candidates for Cabling

You might ask yourself “Why would my tree require cables?” Though trees are strong and beautiful, sometimes they are imperfect and grow in funky, different ways to reach sunlight more or to grow away from a structure, often resulting in poor branching habits or defects such as cracked stems, codominant stems, or included bark. Codominant stems are two similarly sized stems growing away from each other, causing a v-shaped crotch that is prone to splitting. Included bark is bark trapped and growing between two branches or unions. This bark acts as a wedge and makes the crotch more prone to splitting.

Other trees that would benefit from cabling are trees damaged from a storm, impacted by an insect or disease, or that have been pruned improperly away from a utility line. These scenarios often leave behind defects and/or wounds, leaving the tree in a weakened, vulnerable state. Wounds take time to compartmentalize (compartmentalization is how trees heal) and sometimes the tree doesn’t have the resources to close the wound quick enough before decay starts to creep into the heartwood of the tree. Cabling can indirectly assist trees in compartmentalization by supporting particular limbs and giving the tree a better chance of compartmentalizing over the affected area before failure. Limb failure can be the end of it for a tree and potentially damage targets below such as turf, concrete, cars, or structures. Supporting these works of art nature created is an essential part of tree preservation and in protecting your property.

What is Tree Cabling?

Tree cabling is the installation of hardware in a tree to provide supplemental support to weak sections at risk of failure. This will limit movement of branches and help support loads. This is especially beneficial during adverse weather conditions such as heavy rainstorms, harsh wind events, and blizzards. There are two general cabling options: Static and dynamic. Both options have their advantages and proper use cases.

Static Cable

Static cable

A static cable is an extra high strength, galvanized steel cable. Russell Tree Experts commonly uses a 5/16 inch cable with a minimum breaking strength of 11,200 pounds, but other sizes exist. This provides low to minimal stretch or movement. A static cable is an ideal choice for a tree containing moderate to severe damage such as a tear, split or crack. Using an analogy of a broken bone, this is similar to using a splint to prevent the limb from moving in a harmful way. With a static cable, the arborist drills a hole through the stem, terminates the cable using a wedge grip device, and traverses the canopy to the other side to drill a second hole and terminate the system using a come along to tension the cable to make the support more rigid. Although this method of cabling is intrusive, it is much stronger than dynamic cable and will allow less movement. Sometimes this is necessary in order for a damaged tree to stay together.

Dynamic Cable

Dynamic cable

The second option is a dynamic cable. As the name suggests, a dynamic cable allows the tree to sway with the wind and work together to stay upright. A dynamic cable can be seen as a preventative option to help keep the tree together before a split occurs. This is beneficial for trees with poor branching habits or codominant stems. One of the benefits to a dynamic cabling system is allowing reaction wood to strengthen over time, thus making the tree healthier overall. Reaction wood is wood that has formed due to stresses like leaning or bending in order to offer additional strength and support. It is less intrusive to the tree and does not require any drilling. Dynamic cabling is also beneficial for a union with minor damage that is at risk of separating from the rest of the tree. This is an aid to help the tree compartmentalize and work toward creating good structure. Continuing on with the broken bone analogy, this would be similar to using a sling that allows for a little more movement than a splint. 

This cable system is a hollow braid rope that is much softer and does not require the arborist to drill into the tree. The dynamic cable is similar to a static cable in that it must be terminated, but the arborist makes a loop and splices the rope together to make a loop on the limb. Afterwards, the arborist traverses the canopy to make another loop and hand tightens the line to achieve the proper support the tree needs.

Improper Cabling

If a cable is installed correctly, it shouldn’t cause any damage or girdle the tree. A static cable arguably harms the tree during the drilling process, but it should only be performed if the end result is a net positive towards a tree’s health through adding additional support. In the case of a dynamic cable, girdling can occur when a cable loop is wrapped extremely tight around a stem, choking it out and restricting resources to the upper portion of the canopy above the cable. This can happen when a cable has not been inspected/adjusted for multiple years and the tree continues to grow. As a result, the bark and even the cambium layer can be damaged. 

An example of a girdled dynamic cable. ISA Board Certified Master Arborist® Jacob Nau does not approve.

Maintenance

After tree work occurs on a tree, the tree will react and adapt to the treatment slowly over time. Trees continue to grow and sometimes cables need to be adjusted to prevent girdling or to ensure correct placement in the upper 2/3 of the canopy from the union in question to work effectively. The International Society of Arboriculture recommends having cables inspected every 1 to 3 years. All cables should be inspected by a qualified arborist to check the tension and structure of the cable. Wildlife, weather, and UV degradation all play roles in the breakdown of a cable and should be considered by an arborist during an inspection. 

If you suspect that your tree may benefit from cabling, the next step would be to have an ISA Certified Arborist® inspect your tree(s) and provide a second opinion. There is a chance that cabling may be recommended alongside other services such as pruning or bracing. The arborist should have a strong recommendation as to which cable would best support your tree. 

Unfortunately, not all trees can be saved by cabling and in some cases, may require removal for safety purposes. With the proper tree candidate, tree cabling can be a good investment for both your tree and property. The science and art of tree preservation is very rewarding to the arborist as well as the manager of the tree.

The Persian Parrotia

By Walter Reins
ISA Certified Arborist®
November 19, 2024​

A Persian parrotia tree (Parrotia persica)

For a variety of reasons, there are certain trees that never seem to get the attention and use they deserve in our Ohio landscapes. The Persian parrotia is one of those trees. The landscape industry tends to rely heavily on a narrow variety of tree species and the Persian parrotia is often overlooked when considering planting options for the landscape. Let’s shed some light on this beautiful, adaptable, and underutilized option.

The Persian parrotia (Parrotia persica), also sometimes known as the Persian ironwood, is a deciduous tree native to a small range of temperate forests in the Middle East. It can grow up to around 30 feet in height with a mature width of 15 to 30 feet. The crown’s shape is generally round or ovular and you may encounter trees grown with either single or multiple stems. The mature size of this tree alone makes it a noteworthy species as this medium size at maturity is often hard to come by and is typically satisfied with trees like river birch or linden. The former often has major health issues with central Ohio’s urban soils. Parrotias tend to be tolerant of less than ideal soil conditions once established, making them a good choice for residential, commercial, and municipal landscapes. Consideration should still be given to location on any property with regard to overhead wires as a 30 foot tree may still be tall enough to interfere with these utilities.

Fall color of Persian parrotia. Note the ~4 different colors of its leaves!

In addition to a desirable size as an accent or shade tree in the landscape, parrotias feature attractive dark green foliage with a gentle serration along the leaf margin. Avid gardeners and tree enthusiasts may find that parrotia foliage resembles that of witch hazel and fothergilla. This is because all three of these species belong to the witch-hazel family (Hamamelidaceae). Fall color is among the best you can find, with blends of yellows, oranges, pinks, and reds that almost seem to glow at the peak of fall foliage season. After the leaves drop, the tree continues to provide winter interest with a beautifully smooth and mottled bark, not unlike the mature bark of crape myrtle or lacebark pine. Flowering in central Ohio occurs in late winter and is not particularly showy. Parrotias are cold hardy to zone 4 (5a), making it a great match for central Ohio winter temperatures.

When planting a parrotia, the selected site should receive full sun to partial shade. Even though the species is tolerant of a variety of soil conditions, including soil pH and somewhat poor soil structure, the site should be well drained and not prone to standing water. With proper location to accommodate its future mature size, correct planting methods, and aftercare, parrotias can be healthy and beautiful additions to an Ohio landscape for several or more decades. Best of all, they are readily found at Ohio plant nurseries and garden centers, making them a tree species that you shouldn’t have to go too far to find! Happy planting!

Firewood Cutting and Safety Tips!

By Mitch Lippencott
ISA Certified Arborist®
October 31, 2024

Fall is the time for football, leaf-peeping, pumpkin spice everything, and if you're like me, SO! MUCH! FIREWOOD! to process!!! In my twenty years of heating my home almost exclusively with firewood, I have learned a lot of tricks that inevitably came with learning from my mistakes. The following is a list of safety reminders and veteran advice for processing and burning wood in your own home. 

GETTING STARTED

When getting started, have a professional inspect and clean your chimney, stove, and/or fireplace annually. For heavier users like me, a second cleaning may be needed mid-winter. NEVER burn until recommended repairs are completed.

Keep fire extinguishers charged and easily accessible. Know how to operate one! Use appropriately aged hardwood species. For example, conifers should never be burned indoors. Never burn poison ivy or wood with vines you can't identify, even outdoors. Wood must be cut or split and sit long enough to allow moisture content to drop. This will typically take a minimum of 6 months. Wood with conks or mushrooms have sat too long.

Add an appropriately sized venting chimney cap to keep animals out (ask me how I know) and to protect against water damage. Water-loving tree species (ex: willow, cottonwood, and sycamore) are not dangerous to burn, but do not produce enough heat to warrant the effort.

CUTTING LOGS

Before cutting any logs, measure your stove’s opening to determine the size of your chainsaw cuts. Cuts that are too short wastes effort and time. You also don’t want to deal with the frustration of having an oversized piece of firewood that won’t fit through the door no matter how hard you try to force it or no matter how many times you rotate it. Ask me how I know… If you care about your back and chainsaw chain, you can cut your firewood on stacked logs or palettes for better work positioning. I strongly advise using a modern chainsaw with all safety features in place. Below is a video we’ve made on chainsaw maintenance and safety!

When using a chainsaw, I recommend staying safe and wearing personal protective equipment (PPE) such as ankle-high boots, chainsaw pants or chaps, hearing protection, and eye protection. If you want to complete the arborist look, you can also wear a helmet and hi-vis t-shirt too!  Cut out and discard any imperfections in the wood such as knots, bends, or flaws. These will be hard to split and may not be worth your time and energy.

SPLITTING LOGS (BY HAND) 

Splitting logs can be physically strenuous labor complete with bends, lifts, and cardiovascular stress. Be honest about your fitness and pace yourself! On the flip side, pre-cut and pre-split wood can be purchased relatively easily. It's far cheaper than a heart attack! When splitting logs, always wear ear and eye protection. Split logs on a large, flat stump or trunk section in an open space. Use a splitting maul, not an axe, and various metal splitting wedges. Again, make life easy and don't worry about waste - if a log is difficult to split, set it aside, and knock out easier pieces.

One important detail to consider about firewood once you have your split logs is to not move it! Firewood can contain insects and disease that could spread and harm another tree population. One harmful example is how emerald ash borer was first detected in the US around 2002 and wiped out, with no exaggeration, millions of ash trees across North America. The general accepted theory as to how emerald ash borer ended up in the US was through wood in a shipping crate that arrived from China. All of this to say, the exact distance varies based on county, state, and country, but the general recommendation is to burn wood within 10 miles of where it was purchased or from where the wood was split. For more information, DontMoveFirewood.org is a good resource! (not sponsored, just want to spread the message!)

STACKING

Stacking can surprisingly be another physically strenuous task, especially if you rush or try to stack too many logs at a time. Please pace yourself accordingly! When choosing a location, select a space elevated from the bare ground that can also be protected from rain and other weather. Leave a gap large enough to walk through between your woodpile and structures to make logs more accessible. More importantly, this will provide a buffer zone for insects, rodents, and wood decaying organisms between the stack and your house, shed, etc.

When stacking, place the flat side down. Round sides can roll, making the entire stack unstable. Build up corners and outside edges first - gaps in the middle can be filled as needed with less precision. Orient wedge-shaped logs inwards. Shifts or slides will fall harmlessly to the center instead of the whole stack toppling over.

BURNING

Before burning, have an evacuation plan ready that includes calling 9-1-1 in the event of an emergency. When it comes time to burn your firewood,  build up heat little by little. You can first ignite paper and work your way up to cardboard, then kindling, and eventually small logs. Cardboard doesn't burn hot enough to ignite full-sized logs. Burn as hot as possible to avoid buildup in the chimney. Remove ashes to a metal container daily. Wood ashes can increase a soil’s pH, so I would not recommend adding them to a mulch or compost bed unless you know that the pH level is below its optimal range for the trees or plants. Regularly inspect the interior and exterior of the room containing the chimney/stove.

Whether you're a veteran or a newbie, cutting and burning firewood is a physically demanding process with life and property threatening consequences. While the process should be respected with the proper safety procedures, it does not need to be intimidating. For those curious, Russell Tree Experts does not produce or sell firewood, but we do offer local, log delivery for you to process yourself! Safe and happy splitting my friends, those blisters will callus soon enough!

When Do I Call an Arborist?

By Mike McKee
ISA Certified Arborist®
October 3, 2024​

Russell Tree Experts has 20+ ISA Certified Arborists® and 3 ISA Board Certified Master Arborists®!

First of all, what is an arborist? An arborist is a professional that has studied and practices the proper care of urban trees and shrubs. They use a combination of science and skills learned both in the classroom and in the field to perform their daily tasks. Arborists have learned to identify many trees and shrubs along with their preferred growing sites and conditions. They are trained to identify and treat many pests and diseases as well. An arborist can take their commitment to the next level by earning the International Society of Arboriculture (ISA) Certified Arborist® credential, accredited by the ANSI National Accreditation Board (ANAB) for meeting ISA’s standards of training and knowledge in arboriculture.

With this being said, why call an arborist? Unfortunately, many of our calls come when it’s too late for the tree after it has already succumbed to some type of insect, disease, construction damage, and more. Some trees were also planted in the wrong place to begin with, or simply not planted correctly. The following are some examples of the best instances to call an arborist.

A mature tree being protected with fencing for an upcoming home renovation project.

The best time to call an arborist is before starting your project. Whether you are clearing a lot to build a new house, planting a new landscape around your house, or simply planting a tree anywhere, it is always beneficial to have a plan. One such plan may include how to save trees from damage that you want to maintain on your new lot. This requires a lot of planning before, during, and after this process. Planting the wrong tree in the wrong spot is often a problem we deal with in many situations. Many people don't account for the mature size of that river birch they planted just off the corner of the house. Structural pruning at an early age can help trees adapt to the site, even if they were planted in the wrong place. They may not realize that the red maple they planted does not like central Ohio soils. Many trees we deal with are not suited for our soils and require additional plant healthcare just to maintain their health. This can be avoided with proper planning and choices. The list goes on and on. Sometimes just a simple discussion or email can avoid a lot of issues down the road.

Sometimes a visit to a client’s property can be discouraging when arriving on site and seeing the results of preventable construction damage or improper planning that could have been avoided with a properly timed consultation. I once had a contractor tell me that he had never killed a tree. That contractor had apparently never visited a site he worked at 4 to 5 years later to see the results from the construction and damage. Some construction damage can be apparent within the first year, but oftentimes it may take 4 to 5 years before the total impact is realized.

A tree with chlorotic leaves, indicating a potential pH problem or nutrient deficiency that could slowly lead to the decline and death of the tree if left untreated.

When I arrive on a property with trees planted too closely together, planted in the wrong site conditions, and/or planted incorrectly, these inadequate conditions sadden me for the health of the trees. As an arborist, we are trained to see the future impact of plant selections, as well as how they will fit into their site at maturity. Trees planted too close together can often result in stunted growth due to resource competition such as water, sunlight, and space. Unideal site conditions for a tree can lead to numerous, future problems such as leaf scorch and chlorosis just to name a few. An improperly planted tree can result in stem-girdling roots and root rot. A simple consultation in the beginning can avoid a lot of issues down the road. 

My third, most challenging visit is to a recently purchased property. One of the best times to consult with an arborist is prior to purchasing an existing property with mature trees. We often find major problems that could be taken care of before the purchase by the seller or used in the negotiation of the purchase price. Most home inspectors are not trained to identify tree issues. A simple consultation could save you a lot of money on your new home purchase. A recent example is with our Media Production Coordinator (Enrique) who had a pre-purchase inspection by one of our Regional Managers (Mitch) who caught lecanium scale on a crabapple tree and boxwood leafminer on numerous boxwood shrubs that were missed by the home inspector. He was able to bring this to the attention of the previous homeowner who offered to take care of the plant healthcare services prior to closing. In the end, he saved a few hundred dollars by attaining a pre-purchase inspection instead of paying for plant healthcare services.

Another trend that I have noticed lately is insurance companies telling homeowners that they must eliminate all overhang of their structure or their insurance policy will be dropped. Some insurance agents are using Google Earth images to make many of these decisions and not visiting the property in-person to more accurately assess the tree’s risk. This practice could lead to pruning practices that could severely degrade the health of your trees. A property owner that is proactively caring for their trees should not be subjected to this practice. If this trend continues, it will be our job as arborists to help convince insurance companies not to require this practice, especially when it is not appropriate. If you receive such a request from your insurance company, this would be another opportune time to call an arborist.

In closing, the goal of this article is to help people to understand the best time to call an ISA Certified Arborist®. The scenarios mentioned in the article are from recent visits to our client’s properties and are a recurring problem. As an arborist, we are disappointed when we have to tell people to remove a tree that could have been preserved if the proper steps had been taken at the beginning of a project. Tree removal is a part of our business, but preserving trees for future generations is our passion! I hope this helps.

Day in the Life of a Tree Wellness Technician!

By Alex Miller

Green spaces are known to have an endless list of positive effects on mental and physical health, including but not limited to reducing stress, reducing blood pressure, strengthening memory retention, increasing productivity, increasing concentration, increasing creativity, and lowering the symptoms of dementia. This makes being a plant healthcare technician a rewarding profession centered around the essential task of maintaining and enhancing the health of trees and shrubs in the urban landscape! However, it is not without its challenges. Each day is a blend of technical skills, environmental awareness, and client interaction which makes everyday both unique and fulfilling.

One of our plant healthcare trucks!

My day typically begins early, often before sunrise, as I prepare for a day of diverse tasks. The morning routine involves reviewing the day’s schedule, which might include site visits to commercial properties, residential gardens, or public parks. Each location has its own set of plant health issues, so preparation is key. I check for any special instructions or updates related to the plants I will be treating, ensuring that all necessary equipment and supplies are loaded into the truck. Often, I am aware of the issues I am treating, but not always. If I can, upon arriving at the site I try to meet with the client, if for nothing else, to let them know who’s walking around their property. Then my role will shift into diagnostic mode or straight into treatment. If I am doing an inspection, this involves carefully inspecting plants for signs of distress, looking for telltale signs of pests, diseases, or nutrient deficiencies. Detailed observations are crucial. For example, yellowing leaves might indicate a nutrient imbalance, while holes in leaves could suggest an insect infestation. I take lots of notes on these observations and sometimes collect samples for further analysis.

A significant part of my day involves applying treatments. This could mean spraying pesticides, administering fertilizers, or implementing soil amendments. Each treatment requires precision to ensure that it targets the problem effectively while minimizing impact on the surrounding environment. I follow a lot of safety protocols, wearing protective gear and adhering to regulations regarding chemical use. Often, I will simply report my findings and allow the regional manager who is more familiar with the property to engage in consultations with clients. This involves explaining findings, recommending best practices for plant care, and discussing potential improvements to enhance plant health in the future. As my workday progresses, I am constantly logging data; documenting treatments I’ve applied, the observations I’ve made, and the outcomes I’ve observed. This helps track the progress of each plant and plan future interventions.

Root zone invigoration using an air excavation device!

An often-overlooked aspect of working in various outdoor settings is dealing with the occasional mess left behind by others. For instance, it is quite a relief when I encounter a site where pet waste, such as dog poop, has already been picked up. It not only improves my working conditions, but also ensures that I can focus on plant health without any distractions. This small but significant detail can make a substantial difference in my day’s workflow as dragging a hose through a backyard without hitting any landmines can sometimes be a challenging task. It is a simple pleasure that certainly enhances the overall experience of the job. In addition, it is incredibly helpful when clients are able to prepare for my arrival by moving bird feeders, yard art, or furniture out of the work zone. This thoughtful preparation allows me to focus on the task at hand and leads to a smoother and more efficient workflow.

Vertical mulching a tree suffering from soil compaction!

My day typically ends with a review of the completed tasks and preparation for the following day. I may plan out my next set of site visits and ensure all necessary tools and supplies are working and ready. There’s also a period of reflection on the day’s work, assessing what went well, and what could be improved. However, not every day is perfect, and there are challenges such as inclement weather or unexpected complications with plant health issues that may lead to delays. This can of course be frustrating for clients because some interventions may have a very narrow window of effectivity and may have to take priority of certain tasks that have a much wider range of time to be effective. Communication here is the key to ensuring tasks are getting done in their appropriate time frame and clients are satisfied with the work they are receiving. One of the more gratifying aspects of my job is the opportunity to visit sites year-to-year, or sometimes even a few times a year, and witness the positive outcomes of my interventions. There is something deeply rewarding about seeing a plant bounce back from the brink of disease or pest damage and seeing it full of life and vigor; especially after you have put in the effort to nurse it back to health.

In summary, a day in the life of a plant healthcare technician is a dynamic blend of technical expertise, hands-on problem solving, and client interaction. It involves diagnosing and treating plant health issues, applying treatments, and offering valuable advice. Amidst the challenges, small comforts, like avoiding the unpleasantness of dog poop, enhance the work experience, making the role both manageable and uplifting by ensuring that plants thrive and contribute positively to humans and to their environments.

How to Prepare Your Trees for Severe Storms

By Chris Gill
ISA Certified Arborist® OH-6416A
April 3, 2025

The word “storm” can take on many different meanings: Thunderstorms, blizzards, ice storms, tornadoes, hurricanes, or one of our crew leaders Storm Wellman! Jokes aside, all types of storm events can wreak havoc on properties, causing significant damage to homes, landscapes, and personal property. Preventing storm damage is crucial for safeguarding your property and minimizing costly repairs. By taking proactive steps you can reduce the impact of severe weather. Regular maintenance and preparation are key to ensuring that your property remains protected when storms occur. In this article, we will explore practical tips to help protect your property against the destructive forces of nature.

WHAT IS "STORM DAMAGE"?

Storm damage occurs when a tree or limbs from a tree fall and damage valued property. This can range from a tree limb falling on your gutter to a large tree falling onto your home. Storm damage results in millions of dollars in property loss every year. 

IS IT POSSIBLE TO PREVENT STORM DAMAGE?

While it is not always possible to eliminate storm damage, steps can be taken to reduce its impact. However, extreme storms may still cause damage despite preventive efforts. See below for useful tips to help you identify at-risk trees and limbs as well commonly employed interventions to mitigate these risks for the future. 

HOW TO IDENTIFY STORM DAMAGE RISKS 

The key to reducing potential storm damage is identifying the hazards. The following are a few simple ways to try and identify potential hazards.

1.    Look for hazardous dead limbs close to your house or other valued property

Dead limbs near a house.

2.    Try to identify declining trees on your property by looking for the following:

• A large number of dead limbs in the canopy of the tree

• The existence of conks or mushrooms which are the fruiting bodies of decay on the trunk of the tree

• In general, a tree that appears unhealthy (missing leaves, loose bark, etc.)

An example of co-dominant stems with multiple brace rods installed.

3.    Locate high risk co-dominant stems

• These are tight “V” type unions 

• May appear as multiple stems originating from one point in the trunk.

HOW TO MITIGATE HAZARDS

Mitigating the hazards within your trees can be done in many ways. At Russell Tree Experts, we can identify general and more noticeable hazards on your property during a tree inspection such as our free anytime quote or optional firm time quote by one of our 20+ ISA Certified Arborists®. Another option to consider is a tree risk assessment containing a thoroughly written report on a suspected hazardous tree. In this scenario, an ISA Certified Arborist® with a TRAQ (Tree Risk Assessment Qualification) will employ various tools and tests from head-to-toe of your tree to assess the overall risk rating of your tree. Once hazards are identified either though a property inspection or tree risk assessment, a full mitigation plan can be put together. This plan may include, but is not limited to, tree pruning, tree removal, brace rod installation, cabling, and lightning protection to make your property safer and more resilient to storms. 

IN SUMMARY

Don’t be scared - be prepared. A well-maintained tree with regular pruning and care will be stronger and more storm-resistant. Proactively identifying hazards and putting together a mitigation plan can help save money as well as reduce headaches when storm events occur. In the event of severe storm damage caused by a tree, Russell Tree Experts provides 24/7 emergency tree services with quick mobilization.

Fall Webworm: An In-Depth Exploration

By Mike Wilson
ISA Certified Arborist®
September 12, 2024​

As a regional manager, I have been hearing many concerns from homeowners about fall webworm over the last few weeks and have seen even more in landscapes throughout central Ohio. Fall webworm (Hyphantria cunea) is a species of moth known for its distinctive and conspicuous webs, which are commonly found on a wide variety of trees across North America. While not considered a major threat, fall webworm can cause significant defoliation in late summer and early fall, leading to reduced vigor and unsightly trees.

Life Cycle of the Fall Webworm

The life cycle of fall webworm is a fascinating process that begins with the emergence of adult moths in late spring or early summer. The adult moths, characterized by their white wings often dotted with black spots, are nocturnal and are seldom seen during the day. After mating, the female moth lays her eggs on the underside of leaves. These eggs are small, white, and laid in clusters, often numbering several hundred.

Within a week or two, the eggs hatch into larvae, which are the most destructive stage of the fall webworm life cycle. The caterpillars are initially light green or yellow with two rows of black spots along their bodies. As they mature, they develop long, silky hairs. The larvae immediately begin to feed on the leaves of the host tree, creating a communal web that serves as both a shelter and a feeding ground. As the larvae grow, the web expands to cover more of the tree's branches. This feeding occurs from late spring to mid-summer. By late August, they typically stop feeding.

The larvae go through several instars (or developmental stages) over the course of four to six weeks. Once they reach maturity, they leave the webbing to pupate in the soil or under loose bark, where they remain until the following spring.

Habitat and Distribution

Young fall webworm insects are highly adaptable caterpillars that feed on a wide variety of plants, including more than 100 species of deciduous trees. Some of their preferred hosts include hickory, walnut, cherry, and persimmon trees.

The webs of the fall webworm are commonly found in late summer and early fall, which is how the species earned its name. These webs can cover entire branches and, in severe infestations, can even envelop small trees entirely.

Ecological Impact

While fall webworm is a pest and nuisance, its overall impact on the urban forest is generally minimal. Most healthy trees can withstand the defoliation caused by these caterpillars, and the damage is typically more cosmetic than lethal. The webs themselves, though unsightly, do not cause direct harm to the tree. The unsightly webs can diminish the aesthetic value of ornamental trees, leading to concerns among tree managers.

Management and Control

Controlling populations of fall webworm can be challenging due to the species' high reproductive rate and wide host range. However, several management strategies can help reduce their impact.

1. Mechanical Control: One of the simplest methods is physically removing the webs from affected trees. This can be done by pruning infested branches or tearing open the webs to expose the caterpillars to predators.

2. Biological Control: Natural predators and parasitoids can help keep fall webworm populations in check. Birds, spiders, and wasps are all natural enemies of fall webworm. In some cases, introducing or encouraging these predators can be an effective control measure.

3. Chemical Control: In severe infestations, insecticides may be used to reduce fall webworm populations. We generally only recommend this if the infestation is extreme or if the tree is of high aesthetic value.

4. Cultural Control: Maintaining healthy trees through proper watering, fertilization, and pruning can help them better withstand defoliation. Additionally, removing fallen leaves and other debris from around the base of trees can reduce overwintering sites for pupae.

Conclusion

In conclusion, although the presence of fall webworm can be unsightly and concerning, they are generally not a serious threat to the overall health of trees. We generally do not recommend treatment of this pest unless populations are excessive, or if a young tree is infested to the point where serious defoliation is a concern.

How to Mulch a Tree Ring with CRISP Edges!

By Enrique Arayata
ISA Certified Arborist® OH-7252A
August 6, 2024

In this article (and video below), we will be going over how to make a tree mulch ring with crisp edges! First, what is a tree mulch ring? In general, it is a circular area of organic mulch around the trunk of your tree. Sometimes the perimeter will be outlined with stone or plastic landscape edging. The benefits of creating a tree mulch ring is that if done properly, it will aid in maintaining the health of your tree and promote increased growth and vigor. We will also be going over common mistakes to be cautious of.

VIDEOS: HOW TO CREATE A TREE MULCH RING

Benefits of a Tree Mulch Ring

More Nutrients: Organic mulch contains a lot of essential nutrients like nitrogen, phosphorus, and potassium that will slowly break down and decompose for the tree to absorb. Examples of organic mulch are mulches made from wood chips, compost, or leaves. Examples of inorganic mulches that would not provide the benefit of increased nutrients are anything made of stones or synthetic materials like plastic or fabric.

Water Retention: Mulch is a natural insulator that will keep the soil warmer in the winter and cooler in the summer compared to the surrounding, ambient temperature. Mulch also retains water more effectively than grass or topsoil. Evaporation is slowed down and more water is available for the tree. This also means that less tree watering may be needed depending on the weather and season. Instead of watering every 1 to 2 days, a deep soaking once or twice per week could be completed with similar or improved results. Erosion is also minimized as mulch will lessen the impact of water droplets hitting the ground and washing away the soil.

Outcompeting Other Plants: Mulch will reduce competition of nutrients, water, and oxygen for the tree from grass, weeds, invasive plants, and more. This results in the tree having more resources to absorb to keep it growing as healthy as possible!

Minimizing Trunk Damage: A mulch ring will minimize or even eliminate any risk for trunk damage from lawn mowers or string trimmers. Someone may not be intentionally trying to damage a tree’s roots or trunk, but accidents happen when trying to mow or trim those last, stubborn blades of grass. If there’s mulch instead of grass near the trunk, then there will be no reason to bring a lawn mower or string trimmer within a close enough distance for accidental damage to occur. 

Soil Decompaction: Soil compaction is bad for a tree because it minimizes gas exchange and water infiltration. A tree benefits from soil decompaction and root zone invigoration if the soil is compacted when digging up the topsoil and is replaced with porous mulch. Peo de ple are also less likely to step on mulch compared to grass which will aid in minimizing soil compaction and keeping it porous for adequate gas exchange and water infiltration. 

Final product of a properly mulched tree ring!

Reduced Maintenance: Although there is an upfront time commitment with installing a tree mulch ring as well as some annual maintenance with re-edging the lines and adding mulch, less tree maintenance will be needed in the future. A tree mulch ring means less grass to mow and less weeds popping up. Revisiting the benefit of increased water retention, this means that less tree watering will be required with certain exceptions like newly planted trees and drought-like weather conditions. A properly installed tree mulch ring and a consistent watering schedule can also minimize the risk of stem girdling roots, soil compaction, drought stress, and some nutrient deficiencies. This makes for a healthier tree and lessened chance for problems that would require tree work services like fertilization, root collar excavation, root zone invigoration, or worse, tree removal.

Aesthetics: Subjectively speaking, tree mulch rings are aesthetically pleasing and can boost curb appeal! It conveys to passersby that you care about your trees and property. You can even make your neighbor Jim from three doors down envious of your lawn! If you start to notice other neighbors creating a mulch ring around their tree after creating yours, you can take pride and credit for being a trendsetter.

Stem girdling roots circling around the trunk of a tree. This is a common symptom a tree mulched or planted too deeply.

Correcting an Improperly Planted Tree: This doesn’t apply to every tree. However, if you are wanting to mulch a tree that just so happens to be planted improperly, this is a great double positive to fix the imperfection while also gaining the aforementioned benefits of tree mulching. Signs of an improperly planted tree are stem girdling roots, mulch volcanoes, and the lack of a visible root flare.

Now let’s move on with how to create a tree mulch ring and avoid some common mistakes!

How to Create a Tree Mulch Ring 

The ISA Arborists’ Certification Study Guide recommends a mulching depth of 2 to 4 inches and a radius of anywhere from 3 feet up to the canopy drip line of a tree.

1. Determine the size of your mulch ring! In general, aim for a mulch ring with a diameter anywhere between 6 feet wide or up to the canopy drip line for a medium-to-large sized tree. The latter is not always achievable however due to obstacles like nearby trees, plants, concrete, and more. As long as the mulch ring is at least 6 feet in diameter, it should suffice! In terms of mulch depth, 2 to 4 inches is recommended, but I like sticking closer to 2 inches deep.

2. Outline your circle and make sure the tree is centered. There are multiple, effective methods of outlining the mulch ring circle. Below are a few popular ways. One might be more effective than the other depending on your tree, such as if there’s a central leader or any low hanging limbs.

1. Method 1 requires a tool like a shovel or edger and some type of long, ovular, band like a piece of rope, tie down strap, belt, or exercise band. Place the tree trunk inside one end of the band and the edging tool on the other end of the band. Set the distance of the band to the desired radius of the mulch ring. Go around the tree in a circle and make a 2 to 4 inch deep cut into the ground until you have a fully outlined circle.

2. Method 2 requires string and a can of spray paint. Cut the string to the desired radius of your mulch ring. Leave some margin on the string so you can tie the tree trunk and spray paint can together and maintain the desired radius. On one end, tie the string gently and securely to the tree trunk and on the other end, tie the string to the spray paint can. An easy knot I recommend would be the bowline knot! Walk around the tree while applying a visible layer of spray paint to create a circular, painted outline. 

3. Method 3 requires a long garden hose and measuring device. Lay down the garden hose in a circle around the tree to create an outline the size of your desired mulch ring. Use the measuring device to check if the tree is centered in the circle by checking for the same radius at various locations between the trunk and the hose.

4. Method 4 requires a measuring device and an edging tool. Measure your desired radius from the trunk of the tree to the edge of the mulch ring and mark the spot by digging 2 to 4 inches into the soil with your edging tool. Move your shovel away from the mark and repeat this process along the circumference of the tree until your circle is fully outlined. 

3. Dig up the top 2 to 4 inches of topsoil within the circular outline! Be careful of any fine, fibrous tree roots. If any are present, consider using an air blower or your hands to gently remove the soil near it. If there’s any grass or weeds remaining after the top 2 to 4 inches of topsoil are removed, consider pulling them out to minimize the chance of weeds or grass growing out above the mulch. Check for a level surface and a well-defined edge and make touch-ups if needed.

4. Dampen the soil to a darker shade of brown and avoid pooling of any water. This could be considered optional on different guides for how to create a tree mulch ring, but I recommend this as a quick, low effort way to add moisture back into the soil. This is especially helpful if you are doing this in the middle of summer with any exposed roots. Avoid placing down landscape fabric between the soil and mulch. This is a common practice of the past that is slowly being phased out because studies have shown this to not be noticeably more effective at blocking weeds, because the openings can clog up with organic matter and minimize air exchange and drainage, and because the decomposed nutrients from the mulch will be blocked from improving your soil and making nutrients more available for your tree. If weeds are a concern, an optional step could be to apply a weed preventer like Preen before applying mulch.

An incorrect method of applying mulch commonly known as a mulch volcano.

5. Evenly apply your mulch! Depending on the specific diameter and depth of your hole, anywhere from 1 to 4 bags could be used. Be cautious of compacting the mulch. You can lightly tamp the soil with your hands to help level the surface, but keep the mulch porous to maximize gas exchange and water infiltration. Do not cover the root flare (also known as the trunk flare) of the tree. This may be a commonly seen occurrence, but that does not mean it’s the correct way to mulch a tree. This is known as a mulch volcano and is bad for the tree! They are detrimental to a tree’s health because they encourage unwanted disease and decay and because the needed oxygen-carbon dioxide exchange for healthy growth is minimized. Keep it simple by applying a level layer of mulch. If you are concerned about water runoff, a tiny, wall-like berm could be created around the perimeter of the mulch ring and formed by hand to encourage water to remain inside the mulch.

6. Touch up the circumference of the mulch ring to make that edge look nice and crisp! You can use a tool like the sharp end of a shovel, an edger, a string trimmer, or a bed redefiner. Avoid stepping on the edge or using a heavy piece of equipment as the edge could cave in and break.

7. Water the mulch! Ideally, it is best to water the tree slowly and deeply using a watering bucket or a drip irrigation device, but you can also use a garden hose on the mist setting and apply it evenly for a couple of minutes to get the mulch damp and moist. Avoid pooling any water and do not get the trunk or leaves excessively soaked for an extended period of time because an environment for disease or decay could be created.

8. Voila, you’re finished! Time to take a step back, enjoy it, take a few pictures, show your friends and family, or whatever else you’d like to do! You might have also created a messy work zone that you may need to clean up!

In terms of future maintenance, you may annually need to redefine the edge to keep it looking crisp and you may need to add a minimal amount of mulch as it decomposes and thins out. To preserve your edge line, avoid mowing directly up to the edge and use a string trimmer to cut the grass 1-3 inches closest to the edge. You can also add stone around the perimeter to make it stand out even more, but this is not necessary in regards to your tree’s health.

Spotted Lanternfly: They Are Here!

August 1, 2024​

In early 2022, I sent out a message warning people to keep an eye out for the spotted lanternfly as it was on the move from our neighboring state of Pennsylvania. Now today in 2024, there are multiple confirmed populations in Franklin County, Ohio. Linked below is a map with confirmed populations:

As a review, the spotted lanternfly (SLF) is an invasive insect that feeds on various plant species, with its primary host being tree of heaven (Ailanthus altissima), but has been seen feeding on over 70 species of plants.

SLF are not harmful to humans as they cannot bite or sting, but they are large in their adult form and look intimidating.

Spotted lanternfly insect are sap suckers and feed on the sap through a tiny, straw-like mouth part. While feeding, they excrete honeydew which has been known to resemble a light rain in forested parts of infested areas. SLF is a plant stressor that, combined with other stressors, can cause significant damage to the host plant. SLF alone may not necessarily kill a tree; it has only been known to kill grapevines, tree of heavens, and black walnut saplings directly.

We need to slow the spread of SLF by checking vehicles and any outdoor equipment for egg deposits. If they are present, they need to be destroyed and not moved across quarantine lines. Eggs are laid in the fall from September to December and will hatch in the spring from April to June. They lay their eggs on trees, decks, houses, outdoor equipment, and cars, and are protected by a mud-like covering, making the egg masses difficult to spot.

Adults begin to emerge in July and remain active until a hard freeze.

When they start hatching, they will look like little black insects with white spots, and they will not turn red until about mid-summer. Watch out for the combination of honeydew/black sooty mold/wasp swarms around your trees, because it could be an indicator of an invasion.

Management options

Contact insecticides can be used by spraying either the nymphs or the adults from May through October. Be cautious of spraying actively blooming plants to minimize the risk of killing beneficial insects. Systemic insecticides can be used to control and kill SLF adults from May through September. Unfortunately, due to SLF being nimble and fast travelers, just because you treat your property or plant material once, doesn’t mean they won’t come back.

Please be diligent about stopping the spread of this invasive pest. When traveling and vacationing this summer, please be diligent in inspecting your vehicles, camping equipment, and basically anything that is exposed and stationary for more than a couple of hours, especially in known outbreak areas.

Some Mites Like It Hot... Ready or Not!

By Krista Harris

July 25, 2024​

As the average temperatures rise, hungry spider mites thrive! These tiny leaf suckers love hot and dry weather and are currently causing many of our beloved foundation shrubs to look sickly and even lose their leaves entirely.

Spider mites on a burning bush

Spider mite damage on burning bush (Euomymus alatus) and on boxwood (Buxus sp.) is common in the summer months. These typically dependably green shrubs will begin to take on a yellow or bronze cast when infested, and, upon closer inspection, a distinct stippling or scratched appearance of the leaves will become apparent. This characteristic pattern is caused by feeding of the mites on the undersides of the plant’s leaves. Many generations of this tiny sucker can occur per summer. A complete generation can take less than a week during 90°F temperatures and without significant rainfall. That’s a lot of babies at 100 eggs per female!

The twospotted spider mite is the species that afflicts the burning bush. These mites will also feed on many other species when available including viburnum, roses, edible plants, perennials and houseplants. In full sun conditions (especially near hardscape like driveways or brick walls) you may see their webbing binding the leaves and even tiny mites moving within the web. This species of mite overwinters as adults in leaf litter and in soil. It's important to clean up and bag any fallen leaves in the fall so that you can reduce the population of these pests before they wake up next spring.

The boxwood spider mite can only feed on boxwood species. This makes it a “host specific” species of spider mite and will not cause damage to any other plants in your landscape. This mite also differs from the twospotted spider mite in that it creates no webs, it feeds on the upper surface of the leaf as well as the bottom surface and it overwinters as eggs on the boxwood plant.

If you want to check your plants for these "pepper sized" pests or suspect you may have a growing spider mite issue, the best way is to firmly smack the twig over a white piece of paper. Look closely and you may see tiny mites crawling on the paper.

As a preventative measure, it is a great idea to give both your burning bushes and boxwoods a heavy spray with your hose nozzle. Do this twice a week in hot, dry weather (over 85°F). Concentrate on the undersides of the leaves especially to attempt to dislodge adults and eggs.

Keeping your plants watered during the summer also really helps to curb serious infestations. If plants are stressed for water, they will be much more likely to become overrun with spider mites and also insect pests like scale, aphids and lacebug.

Deep Root Irrigation: Another way to water!

By TJ Nagel
ISA Board Certified Master Arborist®
July 18, 2024​

Every day over the last couple of weeks I have observed newly planted trees in parks, along streets, and in front yards dry up and lose all their leaves because they are not receiving adequate water. As the weather continues to heat up in central Ohio, this is the time of year to pay special attention to your newly planted trees (and shrubs) to ensure they do not dry out. All trees need water to healthily grow, photosynthesize, and be more resistant to pests and disease. However, newly planted trees (trees planted within the last 3 growing seasons) need extra watering help throughout this time of year because they have limited root systems and less access to moisture. Whether your new trees are deciduous, evergreen, big, small, or listed as a drought tolerant species, it must receive supplemental water this time of year.  

As a quick review, remember that watering is the single most important maintenance factor in the care of the newly planted trees. Traditionally, tree watering should be performed regularly, slowly, deeply and in the area with active feeder roots. For more detailed information on general watering practices check out my article and video on watering HERE! 

Today, I’d like to introduce a new tree watering service we are providing called Deep Root Irrigation (DRI).  DRI is intended to efficiently deliver water to tree roots that need special assistance getting adequate hydration. 

How Does Deep Root Irrigation Work?

With DRI, we use an irrigation lance to penetrate the surface of the soil and inject water six to eight inches deep into the root zone of the tree. Using the lance beneath the surface of the soil helps to bypass turf, groundcover, or weed roots and delivers the water directly to the root zone of the tree.

Additionally, the water comes out of the lance at about 200 psi and splits into four separate streams that help to break up compacted soil and add valuable pore space into the soil profile for future root growth.

Since the water is being injected directly into the root zone of the tree with no chance of run off, the water can be applied to the tree quickly as opposed to the longer, deeper soaking that is required with traditional tree watering that starts above the soil surface. With DRI we can thoroughly apply the recommended 10 gallons of water to a new planted 2 inch dbh (diameter at breast height) balled-and-burlapped tree in 2 to 3 minutes. The amount of recommended water for a tree will vary depending on the particular tree’s size, level of establishment, and planting site.

What Trees Benefit From Deep Root Irrigation?

While tree watering is essential for ALL trees, certain trees will benefit from deep root irrigation more than others such as:

• Newly planted trees in landscapes whose owners are away during the hot or dry seasons. A 2 week gap in watering is all it takes for a tree to dry out while it’s owners are enjoying vacation

• Newly planted trees that are not close to a watering source (park trees, street trees or trees inaccessible by hose)

• Established trees in restricted root zones (ex: parking lots or sidewalk cut outs)

• Trees that recently experienced soil compaction or root disturbance events

• Established trees that have recently received a root zone invigoration

• Trees experiencing stress from insect infestation or disease

• Over mature trees in the beginnings of decline

• Established trees during extreme periods of drought

How Often is Deep Root Irrigation Needed?

There is not a one size fits all answer to this question. Watering is essential to newly planted trees during most of the growing season (May through October). In general, a newly planted 2 inch dbh balled-and-burlapped tree should receive roughly 10 gallons of water once every 7 to 10 days. If you have newly planted trees that you regularly care for, but plan to be away for a short time on vacation during the growing season, DRI is likely to only be needed while you are away. If you have a large old tree that is in the beginnings of decline, a thorough DRI once a month during the summer months will go a long way to maintaining health and vigor. Every situation is different.
