Right Tree, Right Place!

Much of the tree work our arboriculture division at Russell Trees Experts performs is a direct result of trees and shrubs being planted in inappropriate locations.

When we prune trees to clear a house, roof, or utilities, it's often because a large tree was planted too close, or a smaller tree should have been used. When we shear shrubs to stay below windows or to not encroach on walkways, a smaller, narrower shrub would not have needed maintenance. When we repeat micronutrient fertilizations or fungicides, it's usually to support a tree that doesn't belong in its environment. In short, we make wrong trees fit in wrong spaces.

The unfortunate fact is most trees and shrubs need a specific set of conditions to thrive - they can't just go anywhere. While figuratively forcing square trees in round holes is good for our business, the savvy gardener will not pick out a tree they 'like' and plant it in a spot where they think it 'will look nice'. Instead, they will study the conditions of their site, then choose the tree that best fits those conditions.

So how can you, the savvy gardener, 'study' your planting site? It's more than looking out the window once. Measuring is a good idea, but still not enough. Instead, examine your area from multiple vantage points, during multiple weather conditions, and multiple times of day.

Does rainwater pool anywhere? Where does the sun hit, and for how long?  Which direction does the wind come from? Where would privacy be preferred? These, and many more questions should be incorporated into the plan.

While this seems cumbersome, the process can be broken down into five important factors: size, water, soil, exposure, and goals.

1) Size

Yes, plants can be pruned to keep them smaller, but most don't want to be! Severe pruning and shearing can cause stress, which in turn, makes plants less capable of defending themselves against diseases and insects; especially near a house or patio. Research plant sizes and don't get greedy - if a plant gets too big for your space, it's out of contention.

2) Water

As the global climate continues to change, Ohio is experiencing warmer, wetter winters and springs. Few plants can tolerate both wet and dry conditions. So if your area is wet most of the year, only water-loving plants should remain in the candidate-pool. Forcing dry-footed plants to wet soils will likely leach away vital nutrients and cause fungal infections. Conversely, heavy drinkers in dry soils will likely need continuous watering, which is time-consuming, expensive, and environmentally careless.

3) Soil

Soils vary greatly by location, but in general, central Ohio soils have a heavy clay texture with poor drainage, and a neutral pH (neither acidic, nor alkaline). Undisturbed soils tend be more loamy and acidic. New builds and urban areas tend to be more compacted and alkaline. Plants in soils not matching their needs can suffer from fungal infections, nutrient deficiencies, and instability due to poor root growth.

4) Exposure

While sun and wind are obvious factors, deer-resistance, salt tolerance, limited root space, planned or recent construction, and known insect pests or pathogens are other common exposures in our region.      

5) Goals

I will discuss this more thoroughly in a future article because this is the most fun part - this is where all of your research and observation pay off and your plant starts to work for you! Privacy, traffic noise reduction, food production, bird watching, and a created, desired aesthetic are all examples of good planting goals. Luckily, there is a plant for every size and for every site, so be diligent and find exactly what you need. Scott Zanon's excellent guide Landscaping With Trees in the Midwest lists trees for a variety of situations, including photos, plant sizes, and recommended cultivars.

~~

Pairing the correct plant to the correct location may take time and research, but it is the best path to a long-lasting, low-maintenance garden. When planting your next tree, thoroughly observe your site before heading to the nursery, then limit your search to the trees that match those conditions. Just don't get too carried away - we still have a business to run over here! ;-)

Fungicides in Full Effect!

By TJ Nagel
Board Certified Master Arborist®
March 27, 2024

Plant diseases love spring! As temperatures warm and tender new growth emerges, conditions are ideal for fungal pathogens to settle in and take up residence in our favorite trees. It is now when many plants are most susceptible AND treatable for fungal diseases, such as Dothistroma needle cast of Austrian pine, apple scab of flowering crabapple, Rhizosphaera needle cast of blue spruce, rust diseases on hawthorn and pear, and many others. So, rest easy as you see our tree wellness crews all over town arresting pathogenic perpetrators. 

For this article, I want to focus on apple scab because it may be the most aesthetically devastating disease of ornamental trees and it is one of the most common diseases we see daily out in the field. 

What is the disease and what does it do?

Apple scab is caused by the pathogen Venturia inaequalis.  It is a common disease targeting the rose family of plants which includes crabapple, apple, pear, hawthorn, mountain ash, cotoneaster and pyracantha.

Apple scab produces lesions on leaves, flowers, fruit and on young succulent shoots.  When infected areas are numerous, leaves can become curled and distorted and severe infections can lead to complete defoliation of trees and shrubs.

Several years of early leaf loss generally results in poor growth, reduced bloom and increased susceptibility to winter injury and insect predation.

How does the disease work?

Apple scab overwinters in fallen diseased leaves and in the soil. Disease development is favored by wet weather and cool temperatures that generally occur in central Ohio in the spring and early summer. Fungal spores are moved from the ground and carried to trees by raindrop splash and wind where they make their way to leaves, flowers, and fruit.  

During wet periods, newly emerging crabapple leaves are extremely susceptible to infection. The longer the leaves remain wet, the more significant the infection can be. 10-20 days after initial infection, new spores are released which infect new leaves. Repeated infections can continue through the summer until environmental conditions become too hot and dry for the pathogen.

What can be done to protect my crabapples?

For most crabapple trees, fungicides must be applied preventatively to successfully manage apple scab. Fungicide sprays should begin when the first green leaves are emerging with additional sprays being applied in roughly two-week intervals.  The number of fungicide applications needed can vary with weather conditions but generally, we recommend three separate applications.

Other cultural practices that can increase the effectiveness of fungicide applications when managing apple scab are:

1. Raking up and destroying infected fallen leaves to reduce locations where the apple scab pathogen can overwinter

2. Space crabapple trees generously to increase air circulation around trees

3. Prune out crossing limbs, vigorous upright sprouts, and suckers to increase airflow and sunlight penetration into the canopy (this can help foliage dry faster after rain or dew)

4. Avoid overhead irrigation, if plants need watering, apply water directly to the root zone. (Check out this article on best tree watering practices)

Additionally, much breeding and selection work has been performed within the nursery industry to introduce scab-resistant crabapples into the landscape. A short list of some of the most scab-resistant cultivars include:

1. ‘Coralburst’,

2. ‘Donald Wyman’

3. ‘Prairifire’

4. ‘Purple Prince’

5. ‘Red Jewel’

6. ‘Royal Raindrops’

7. ‘Sugar Tyme.’  

Also, selecting a tree that is not a member of the Rose family would be a guaranteed way to avoid apple scab.

Other common fungal diseases of trees that can be managed using fungicides include Oak Wilt, Dutch Elm Disease, Powdery Mildew, Black Knot, Anthracnose, and Verticillium wilt.  

Remember, application timing is important and most fungal diseases of trees and shrubs are treated preventively. Treatments are far less likely to be effective when applied after the disease(s) has shown up. Tree disease diagnosis and treatment recommendations should be made by a professional arborist. Definitive disease identification may even require sending samples to a plant pathology lab. Russell Tree Experts will provide this service if needed or recommended.

If you have questions about fungal diseases of trees on your property, give us a call or request a quote online and we will send an ISA certified arborist to help!

How and When to Stake a Tree

By Walter Reins
March 20, 2024

“Spare the rod, spoil the child” — This is how I like to explain the staking of trees when someone asks about it. Sometimes the quote works, and other times they look at me funny. While it doesn’t do much to explain how to stake a tree, it’s actually a great way to think about why you may or may not want to stake the tree in the first place. Stick with me and I’ll explain.

For starters, I’m not condoning corporal punishment. Maybe you’re familiar with this somewhat outdated expression. To put it in different words, it could mean “Without discipline, a child doesn’t receive the guidance to grow up strong and self-sufficient.” That sounds better, doesn’t it?! Don’t make the mistake of equating the “rod” to the stake, it’s actually the opposite. The rod in this case represents “discipline” or "hard love.” In other words, not staking the tree if you don’t have to. If that doesn’t make sense yet, it will in a couple of paragraphs.

There are a few situations where staking a tree is beneficial or even crucial to its success. But for the majority of newly planted trees, it’s often not necessary. Let’s start with reasons to stake.

When Staking a Tree is a Good Idea

1. An existing or newly planted tree that is “loose” at its base due to wind or improper handling when planted. Trees with trunks that can move around in the soil, even a little bit, are at a greater risk of further damage, lean, or complete failure (uprooting/falling over). Temporary and sometimes long-term support may be necessary to stabilize the tree for its own health and also safety.

2. Newly-planted LARGE trees. These trees often have a much larger canopy-to-rootball ratio, and as a result, are at greater risk of shifting or blowing over from high winds after being planted. They also tend to take longer to re-establish a strong, supportive root system.

3. An existing tree that is exhibiting a lean due to being located in an area with frequent high winds, or a newly planted tree in this same area.

4. Same as number 3 but substitute high wind with frequently wet soil.

5. A newly planted tree being placed on a steep grade or significantly sloped terrain. 
   
   Note: The above list does NOT say to “stake all newly planted trees, period.” Let’s revisit the expression at the top of the page to understand why. 
   

Why Staking a Tree is Often Not Necessary

Trees respond to their environments in some pretty fascinating ways. One of those is by changing the amount and quality of tissue that is grown in response to physical stressors (wind, gravity, lean, proverbial rods, etc.) We can call this geotropism (change in response to gravity) or thigmomorphogenesis (change in response to any mechanical or environmental stimulus). Jeopardy, here we come! When we plant a new balled and burlapped tree, many of (most of) the tree’s original root system was lost when it was dug out of the ground. In the case of containerized trees that have all of their root system still intact, that root system is concentrated into a very small space (within the container) and isn’t spreading out into the surrounding soil, at least not at first. In either case, research has shown that trees will often develop a stronger root system, in the long run and under normal conditions initially, when left unstaked and made to withstand these forces. The jostling and moving about that occurs with a newly planted tree in light to moderate winds, or the forces of gravity placed on a tree that has to overcome a slightly sloped terrain, will actually stimulate growth of the root system, much the same way our muscles will grow in response to first being stressed in a workout and technically damaged, but then recovering bigger and stronger than before. To further build on that analogy, that same response can be impacted by other factors, just like in people, like overloading (damaging high winds for a tree/a person trying to lift too much in the gym) or lack of proper nutrition (which impedes proper healing and growth, whether you’re a tree or a person). Under normal conditions, a tree will strengthen its root system and eventually be able to withstand greater forces exerted on its ever-growing canopy.

We’ve discussed when a tree should be staked, and when it shouldn’t. Now let’s talk about how to properly stake a tree when it’s deemed necessary. For the purpose of this article, I’m going to refer to two different types of support as “staking”. This includes actual staking, but also guying. When staking a tree, the materials used and where/how they are installed are very important.

The Stake

For smaller applications, wooden stakes or metal posts may be driven into the ground around the tree, just outside of the root ball (1-2’ form the trunk) or up to a few feet away if conditions require it (space restrictions can sometimes dictate stake placement). Stakes can commonly be 5-6’ in length and driven 1-2’ into the soil, depending on the structure of the soil and how easily it may loosen over time. They can be driven into the ground upright or at a slight angle away from the tree to compensate for the slight pulling forces, towards the tree, that they’ll be subjected to. Use a pole/stake pounder or a sledge hammer to drive the stakes into the ground. It might help to employ a second person for this - best to let them hold the stake. Like trying to swat a fly on someone’s head, it is always better to be the one swinging and not the one being swung at! The number of stakes or posts around a tree can vary, depending on the environment and reasons for staking. A tree subjected to frequent winds always coming from the same direction may simply need one stake upwind from the tree to prevent it from leaning or blowing over in the direction of the wind. A tree in the center of an open backyard, subject to wind from all directions, would do better with 3 stakes, placed in a triangle pattern, to support in all directions.

For larger applications, guying a tree with metal ground anchors may be a better option. A guy wire typically runs from a strong anchor point on the tree down to an anchor inserted in the ground. These are augur-type anchors that turn into the ground and provide an attachment point for wire running from the anchor to the tree. Turnbuckles can be used in these situations to achieve the proper tension on the wires if they’re supporting a tree of significant height and/or spread. This application is rarely something to be undertaken by a homeowner, and is usually performed by a landscape company as part of the initial installation of the trees. However, a homeowner may choose to implement this setup if adding support to an existing established tree that is starting to exhibit a lean due to winds, a damaged root system, or saturated ground (Caution: If you have any doubt as to the stability of a substantially sized tree that appears unstable, do not attempt to remedy it yourself. Call a professional tree care company and have the tree assessed immediately). 

The Wire or Strap

There are a number of materials that can be used to connect the tree to the stakes, but no matter what it is, one rule should always be followed - it shouldn’t damage, cut into, or compromise the tree’s branches or bark in any way. Wire remains a cheap and effective material to use, but it’s crucial that it not be directly wrapped around the tree. This will cut into the bark and possibly girdle the stem where it makes contact. Instead, short sections of old garden hose can be cut and used, with the wire running through them, to provide a soft and wide surface to make contact with the trunk of the tree. Straps or rope, if used instead, should be wide enough that they do not cut into the bark. Thin-barked trees such as Red Maples are extremely easy to damage if improperly staked. There are of course many store-bought, application-specific options to choose from that can work wonderfully and provide the right support. Whatever material you are using, the tension between stake and tree does NOT need to be extreme, and should instead be appropriate for the environment. Just enough to prevent excessive movement is usually appropriate. Strong winds or a tree with a larger canopy will call for more tension. Imagine Hippocrates planting this tree and, “First, do no harm.”

A few more points

There are a few more points worthy of mention. If you determined that a tree needed staking, and after having successfully staked said tree, consider the following: 

• Check the tree regularly. Every couple of weeks, check to see if the stakes have shifted or loosened in the ground. Check the portion of the support wire or straps that wrap around the tree for any signs of rubbing or wear that could potentially compromise the bark if left as is. Adjustments in tension or placement of support may be necessary.

• Remove the stakes after a year. Generally, one full year of root growth and settling of the soil is sufficient to anchor the tree in place and provide adequate support, under normal conditions. Leaving stakes for longer than this can adversely affect the tree’s ability to adapt to its environment.

• Fertilize the tree for the first several growing seasons. A growing tree will use all the nutrition you can throw at it (responsibly, left-over Timbits don’t count!). Fertilizing a new tree encourages root and shoot development by providing essential nutrients often lacking in our urban landscape soils. A properly planted, staked as-needed, and well-fed tree is on its way to providing many years of benefit to the landscape.

HOW-TO GUIDE

A Note about Evergreens…

There’s one more application of staking that you’re perhaps wondering about, and curious why I have mentioned it or discussed how to do it - the staking of evergreens with a diagonal wooden stake strapped against the trunk. I’m mentioning it, but not recommending it. This is a very common way for evergreens to be staked, typically when installed by a landscape company, and a very common way to cause long term problems if forgotten about. In the 25 years I’ve been working in the green industries, I’ve seen countless examples of these stakes having been left in place, forgotten about as the tree put on new growth and concealed the stake and support materials. Out of sight, out of mind. This often leads to a girdling of the main stem (trunk) at the location where the strap or wire was placed, years after planting, and only discovered when the top half of the tree suddenly and “mysteriously” starts to die. If you absolutely must stake a tree in this manner, use natural twine, not any synthetic material to attach the wooden stake to the tree. This will break down after 1-2 years and is much less likely to girdle the main stem of the tree if forgotten about.

Remember, the staking of a tree is unnecessary more often than not. When you or a professional deem it a good idea, proper stake installation with appropriate materials will ensure that the stake benefits the tree and causes no long term harm. Please note that Russell Tree Experts does not offer the planting or staking of trees, but is always happy to provide professional advice for all things tree and shrub related.

Spring: A Great Time to Fertilize

By Chris Gill
March 7, 2024

Dear Reader,

Spring is a great time to fertilize trees. As the soil begins to warm up, feeder roots become active and begin to look for nutrients in the soil. A general Spring fertilization provides trees with a boost of macronutrients (typically nitrogen, phosphorus, and potassium) which are essential to trees as they enter the challenges of a new growing season and require energy to develop new leaves, branches, and roots. Spring fertilization can also benefit trees recovering from the winter stresses of cold temperatures, desiccating winds, and potential exposure to de-icing products around tree roots. 

At Russell Tree Experts, we fertilize trees through a technique called deep-root fertilization. We perform deep-root fertilization by using a lance to inject liquid fertilizer under pressure deep into the feeder root system in a soluble form that is easy for the tree to take up. This is superior to a traditional surface application where a granular fertilizer is spread over the root system of a tree but still requires time for the product to break down and work itself into the soil. Deep-root fertilization allows nutrients to pass by the competitive roots of turf, weeds, and other ground covers to maximize uptake for the tree. The process of deep root fertilization also helps to loosen up compacted soil around the tree to promote better root growth while also allowing water and oxygen to more easily reach the roots. Compacted soil is a common problem in urban landscapes and can reduce a tree’s ability to access nutrients.

STEP 1: Fertilization

In the spring or fall the soil around the tree will be fertilized with a custom selection of the following: Nitrogen (N), Phosphorus (P), Potassium (K), Iron (Fe), Manganese (Mn), and liquid compost - all essential nutrients for healthy soil and root systems. The goal is to provide the tree with the best soil chemistry possible.

STEP 2: Metabolic Processes

The tree acquires carbon, hydrogen, and oxygen from the atmosphere and from water. Using light energy from the sun (photosynthesis), these are combined to produce glucose. Other essential nutrients are gathered from the soil. The tree uses glucose and essential nutrients for growth, reproduction, and pest/disease resistance.

STEP 3: Evapotranspiration

Through this process the tree is able to move nutrients from the soil, up the trunk, and into the outer canopy, carrying them dissolved in water to be used as needed. This process continues throughout the growing season.

STEP 4: Reduced Nutrient Levels

In urban soils macro and micronutrients can be depleted for several reasons, limiting metabolic processes. Fertilization helps maintain nutrient availability to trees by supplying needed elements that have been used by the tree or leached out of the soil. [BACK TO STEP 1]

Trees that are showing dieback in the canopy, poor leaf color, stunted growth, or low vigor are all great candidates for fertilization. When putting together a fertilization plan, it is important to also consider tree type and location. Most trees benefit from a general fertilization, but many tree species may require more specific nutrients. Some of these nutrients can be lacking in urban and highly developed environments. For example, many woodland species that grow naturally in low-lying areas (ex: river birch, pin oak, and red maple) often require the addition of manganese to a fertilization program for long-term health and vigor when planted in a residential neighborhood. The specific nutrient for which a tree is deficient may not always be obvious, especially in a young or newly planted tree, but can be determined easily through soil and tissue testing. Russell Tree Experts can provide these testing services as needed.

Trees in native areas are less likely to require fertilization. This is due to the less disturbed nature of the soil and to the natural breakdown of leaves, sticks, and other organic matter continually providing nutrients to the soil or a “natural fertilization.” Trees in urban or highly developed areas are less likely to experience “natural fertilization” due to interference from hardscapes and through regular landscape maintenance practices including raking out yards and landscape beds. 

Soil quality is the key to good tree health and longevity and Spring fertilization is a great way to start the soil improvement process. There are various considerations that are made when selecting a fertilizer for your trees including the type of tree and the location of the tree in your landscape. Consulting with one of our certified arborists can help determine the specific nutritional needs of your trees and get the process started!

Tree Bracing 101

Dear Reader,

Trees adorn our landscapes, offering shade, beauty, and a connection to nature. However, ensuring their structural integrity and stability is vital for their longevity. Common tree preservation services that you may be familiar with are tree pruning and mulching. Other uncommon services could be cabling or trunk injections depending on the specific tree. However, throughout my 4+ years of working at Russell Tree Experts, one service that I have not heard of up until this year is tree bracing! Let's delve into the world of tree bracing to understand the process and benefits!

What is Tree Bracing?

Tree bracing? I couldn’t initially picture what this meant when first hearing it. Let’s first break down tree bracing into two words. Tree. Bracing. Tree: A woody, perennial plant typically having a single stem. I know what that is. Brace: To make (something) stronger or firmer, or to prepare for something difficult or unpleasant. So would it be a solid guess that tree bracing is the process of making a tree stronger? Yes! That’s exactly what it is!

Tree bracing is a tree preservation service to reduce the risk of two or more stems from splitting apart or to fasten a split or cracked union together, thus improving the overall structure of your tree. This is achieved through the installation of brace rods to prevent select tree unions from spreading or twisting apart or to prevent a split or cracked union from worsening.

This sounds great! Let’s start bracing every single tree to improve their overall structure! Well, not so fast. Only certain trees will stand to benefit from tree bracing. Just like fertilizing trees with manganese or iron to treat a manganese or iron deficiency, this service is only recommended for trees that need it, otherwise there would be either no noticeable effect or even a decrease in structural rigidity. Just like with pruning, which involves removing (or “wounding”) the tree’s crown of undesired parts, bracing is a semi-invasive procedure that involves installing large threaded steel rods into the trunk of the tree, so we only want to install brace rods when the net result is positive and beneficial. 

What Trees Should Be Braced?

So what trees should receive tree bracing? Well, as mentioned earlier, trees with a split or cracked union could benefit from brace rod installation. A split or cracked union should be easy to spot, especially in the winter in the case for deciduous trees as there is little to no foliage. A limb can split or crack due to various reasons like included bark (bark that is partially or fully embedded into the tree’s wood), improper pruning, disease, and storm damage from adverse weather like lightning, heavy winds, rainstorms, and thick layers of ice just to name a few. A split or cracked union can also occur from structural defects like large, long, horizontally growing limbs and codominant stems. If the limb is large and long and growing more horizontal rather than vertical, there could be a lot of weight-related stress near the union that could cause it to split if the limb is not supported properly or if end-weight reduction pruning does not occur. Codominant stems are two similarly sized stems originating from the same point of the tree and growing in the same, general direction. They can be characterized as having a tight “V” shape near the union or by both of the limbs competing to be the central leader of the whole structure. This is not ideal for a tree’s structure as they are prone to splitting during adverse weather conditions. In scenarios where removal of the branch or tree is not viable or preferred, tree bracing serves as a beneficial solution or alternative.

What Are the Benefits to Tree Bracing?

Tree bracing can be beneficial for a tree as they can minimize movement, ensuring the splits or cracks do not occur or worsen, especially during strong weather. A tree with poor structure or a split or cracked union may not want to be removed by the owner as it is a specimen tree (a tree chosen as a point of focus in a landscape) that provides aesthetics, shade, real estate value, or more. For some trees, it may also be unnecessary to remove them simply because of one or two weak, treatable unions that could even be healed over time. Tree bracing aims to improve the tree’s structure at a choice union and to give its owner more peace of mind that a union or limb has a decreased chance of failing, which would potentially end the tree’s life, or to keep it from falling onto something like a house, car, driveway, or anything else near the tree.

The Tree Bracing Process

Here at Russell Tree Experts, we use the ANSI A300 Tree Support System Best Management Practices to help guide us! With that said, before tree bracing begins, we typically prune the tree's crown to reduce weight and then install one or more cables in the crown to support the suspect union(s) from above. Once these initial steps are complete, we install a specified size and quantity of brace rods in your tree in accordance with the ANSI A300 Tree Support System Best Management Practices. The size and quantity is determined by factors such as the tree’s diameter below the union, number of limbs or unions being cared for, and whether or not there is or is not a split or crack present. To install the brace rods, holes are drilled straight through the tree near the union. The threaded brace rods are then fully inserted and will have excess rod on both ends. The brace rods are then secured with one or more washers, a lock washer, and a nut on both ends. The connections are then tightened as firmly as possible. Afterwards, the excess length of threaded rod is cut off close to the nuts and subsequently peened off to prevent any movement of the nuts. And voila! The end result is a tree with increased structural integrity and a reduced chance of failing! 

I talked with my coworker Jacob, our Training & Development Manager and an ISA certified arborist, read through the ANSI A300 Tree Support System Best Management Practices, and looked at other resources online to see if it was an acceptable practice to drill holes through a tree to install brace rods. After considering a variety of sources, the general consensus is that the overall impact is minor because almost all of the drilled wounds are filled with threaded steel rod (except a 1/32'' gap), allowing the tree to compartmentalize the wounds rapidly, and that tree bracing should be done on trees that have a bigger concern to worry about, such as two codominant stems or a split union.

Professional assessment is imperative to determine the necessity of bracing for a tree. Signs such as co-dominant stems or split or cracked unions should prompt owners to get an opinion from an ISA certified arborist. After researching, observing, recording, and photographing various trees being braced, I felt empowered and motivated to share my newfound knowledge on this not-so-commonly heard of tree preservation service! The main purpose of this Arbor Ed article is to educate and share my findings, but Russell Tree Experts does provide tree bracing services should you want or need it! Our regional managers are all ISA certified arborists and can provide a free inspection and quote! Below are some videos about tree bracing!

Root for your Roots!

A tree is only as healthy as its roots. Luckily, Russell Tree Experts offers a variety of root-health services! The powerhouse of our root-health services is the air spade. This tool, when attached to a powerful air compressor, is capable of removing soil without damaging tree roots. (Full disclosure and fun fact: air spading is my very favorite type of tree care to perform!)

Root Collar Excavation

“Say NO to Girdling Roots!”

The most common root-health service is root collar excavation. In this procedure, our technician begins at the tree's trunk and removes soil approximately a foot outwards to reveal the root system closest to the tree. From here, roots that are squeezing the trunk or each other can be selectively removed, thus improving the passage of water and nutrients from the roots to the leaves. Once the soil near the trunk is removed, additional improvements can be made such as removing twine, burlap, or other nursery products left during planting, or correcting the soil depth of trees planted too deep. In my experience, this is the single most beneficial process to long-term tree health. Maples and sweetgums are especially prone to girdling roots. Signs of trunk girdling in other trees include lack of flare at the base (which indicates the tree is planted too deep), flat spots in the otherwise round trunk, early fall color and leaf drop, and excessive stress during summer drought. Root collar excavations should be performed in winter when trees are dormant, but when the ground is not frozen. 

In limited quantities, roots can also be exposed and pruned to prevent damage to patios, driveways, or underground utilities. This method of root removal is far less damaging to tree health than traditional shovel/backhoe techniques. An ISA Certified Arborist® should always be consulted before this type of work is performed because excessive root removal can cause instability and rapid tree death. Air spade trenching and root removal can be performed year-round except in the case of some trees that may be highly stressed or experiencing severe drought conditions.

Even when a tree is planted at the proper depth, has plenty of soil space, and with no girdling, the trunk can still benefit from root-health services. We offer three related, but progressively more intensive options to treat the entire root zone and not just the area around the trunk.

Vertical Mulching

Vertical Mulching

The first is vertical mulching, in which the technician removes soil in small bursts radiating outward from the trunk and extending the entire drip-line of the tree. The small but 8-12 inch deep cavities are then replaced with a porous and nutrient-rich compost blend. The result is a looser, more aerated soil structure for new roots and beneficial microorganisms to expand into. This service can be provided almost year-round (frozen ground/drought excluded) and is my go-to for mature trees on undisturbed sites that are beginning to lack vigor.

Radial Trenching

Radial Trenching

One step up, radial trenching is a similar procedure, but instead of small bursts, the soil is removed in continuous lines radiating outward the length of the canopy. I prefer this technique for new builds and areas with recent compaction, urban sites, and situations where old trees are beginning to decline. This is another almost year-round service.

Root zone Invigoration

The most extensive of entire root zone services we offer is root zone invigoration. In this technique, we use the air spade to remove all the grass, soil, or competing plants sitting on top of the tree's root system. We then correct any girdling and planting depth problems. Finally, we replace the entire space with our compost blend. This is a big, messy, expensive procedure but often the best solution when a valued small to medium-sized tree is being damaged by mowers, vandalism, or when there is an especially dense or aggressive plant growing above the root zone. I prefer this service to occur during winter dormancy, but in extreme cases, it can be performed any time roots are too restricted to function properly.

It’s easy to forget about your trees while they're sitting leafless in winter - but this can be the most beneficial time to give them attention. Caring for your tree's roots is often more beneficial than pruning, spraying fungicides, or almost any other plant health care service.

Tree Work in the Winter?

Dear Reader,

“Can we get this work scheduled before winter kicks in?” “Do you complete tree work during the winter?” These are questions that I am often asked as the hibernal or winter soltice has arrived. In many cases, winter is the only time we can complete certain projects. This is due to the fact that many diseases and insects are not active, wildlife regulations are not in effect, visibility is increased, and the impact on landscapes is lessened due to winter’s colder conditions. Winter can be the perfect time for tree work.

One example of projects that must be completed during the winter is anything that falls under federal bat tree regulations. This typically includes public property projects where large trees need to be removed or the removal of any tree that could be a nesting site for bats. These regulations are intended to protect the Indiana Bat and the Northern Long-eared Bat, which are both currently endangered species. The importance of bats in our ecosystem is a story in itself. Bats typically overwinter in caves but move out to their nesting sites as early as April, therefore removal of possible nesting sites is regulated from March 31 through October 1. This is the main reason that the majority of our clearing operations and trail creation projects are completed during the winter months.

Winter is also also an opportune time for tree pruning to minimize the risk of insect and disease issues. For oak trees and elm trees, oak wilt and Dutch elm disease respectively are two devastating diseases that are be transmitted by insects (and root grafts) attracted to fresh pruning cuts. (Learn more here!) These insects are typically not active during the winter months, thus making approximately October 15th to March 31st the preferred time to prune oak and elm trees. If pruning cuts are required outside of this time window due to reasons such as storm damage, we highly recommend painting the cuts to minimize the risk of attracting the insects that can spread these diseases. Other trees that can benefit from winter pruning is the Rosaceae family which includes apples, pears, plums, and other fruit-bearing trees. The pathogens that infect many of these trees with diseases such as fire blight and black knot are typically not active during the winter months. Black knot is also much easier to see and prune out when the leaves are not present on our plum trees. Sanitation between cuts and proper disposal of these branches is imperative to slow down the spread of this disease.

Another reason for performing tree work during the winter months is the minimization of turf impact. Winter typically provides an absence of perennial and annual plants that are often planted under trees. Clients also tend to store their yard art, furniture, and other items that could be damaged during pruning and removal operations. This allows for our crews to be more efficient as less time is spent preparing the drop zone and moving items to a safe location prior to beginning any tree work. Thirdly, the winter months tend to be colder which provides a harder, sturdier ground that is more resilient to damage from limbs or equipment. As always, we do place mats on the ground if turf impact is a concern regardless of the time of year. Therefore, winter pruning becomes much more productive since there are fewer items that could be damaged otherwise.

Certain job sites such as golf courses, public parks, and street tree pruning, just to name a few, are performed during the winter months as there tends to be less pedestrians, allowing for better focus, less interference, minimized risk, and overall a more efficient and safe work zone.

As you can see, there are many reasons for scheduling a visit from your ISA certified regional manager this winter. With the absence of leaves on the trees, it is much easier for the trained eye to identify structural issues. Some structural issues may require a cable or even brace rods to secure your favorite tree in your landscape. Winter is also a great time to observe decay, fungi, or other pathogens that may not be visible during the summer when leaves are abundant and present. It is also the best time to observe cavities throughout the tree that may not be noticed while leaves are present. Dead, diseased, and broken branches are also much more visible when the leaves are not present in the winter months. Our arborists are trained to be able to identify the difference between dead and live branches even during the winter months. This time also allows the arborist to make quick decisions on improving the structure of the tree while pruning in the most efficient time of the year. Every day is a good day for tree care!

10 Boxwood Alternatives

Dear Reader,

My introduction into the horticultural world was working at a small retail nursery in the early 2000s. Back then, when a customer would ask for an easy to grow, low maintenance, no brainer plant, boxwood is what we would often recommend. Fast forward twenty years and today boxwood have to contend with boxwood leaf miner, boxwood psyllid, spider mites, volutella stem canker, winterburn, boxwood blight and most recently, a new disease known as boxwood dieback. Historically, Boxwood have been appreciated in the landscape because they are evergreen, deer proof, compact, easy to manipulate and respond well to pruning/shearing. But they are no longer the maintenance free, easy to grow plants they once were. 2023 was a particularly bad year for boxwood in central Ohio and every arborist, landscaper and plant person I know was overwhelmed with calls from desperate clients willing to try anything to restore their boxwood to how they once looked. Many of the boxwood installations I observed this year are beyond preservation. Others will likely recover over the next two to three growing seasons but may look a little rough along the way. Much of the damage that occurred to boxwood this year is a result of the cold weather event we had just before the holiday season of 2022, where temperatures changed from 40 degrees Fahrenheit into the negatives in less than 12 hours. There is no topical spray or any professional service that can be offered to combat this sort of environmental event. And many of the boxwood that were able to survive the initial cold temperatures succumbed later to disease spreading pathogens seeking a stressed and vulnerable host. Even under normal weather conditions, most boxwood require regular applications of insecticides and dormant oils to protect them from insect pests that have taken advantage of their abundance. The best management strategy for the prevention of disease and insect pests on our plants is to use plants that do not get those diseases and insect pests. So as you are wrapping up your Fall landscape plantings or making plans for next Spring, consider something new for your hedges, accent plants and foundation plantings. Here are 10 suggestions for plants to consider with similar characteristics to boxwood.

1. Blue Holly

Blue holly (Ilex x meserveae) is a hybrid between the cold hardy Asian prostrate holly (Ilex rugosa) and English holly (Ilex aquifolium). It is one of my personal favorite evergreen shrubs and has lustrous dark green/blue leaves and dark red berries on female plants that ultimately feed the robins and mockingbirds around late winter to early spring. Individual plants form a shrubby upright to pyramidal habit and can grow 8 to 12 feet in height by 6 to 8 feet in width. Blue holly (Ilex x meserveae) can easily be pruned into hedges and can be kept at any height or width with minimal, annual pruning. They are cold hardy to -20 degrees Fahrenheit and adaptable to both full sun or partial shade. Several cultivated varieties of this hybrid exist with my personal favorites being Blue Princess and Blue Prince.

NOTE:  Holly plants require a male pollinator to achieve fruit. Make sure to include at least one male plant (like Blue Prince), and possibly more depending on the size of your Holly plantings to improve fruiting.

Negatives: Blue holly (Ilex x meserveae) can have significant leaf burn when temperatures drop below -10 degrees Fahrenheit (although established plants recover quickly in the Spring). They are susceptible to phytophthora (root rot) in poorly drained sites and deer browsing during the winter when snow persists for days at a time.

2. Privet

Privet (Ligustrum spp.) is a densely branched shrub with dark green to yellowish green leaves that can easily be manipulated into rounded plants and hedges. Privet (Ligustrum spp.) is fast growing and adaptable to a wide range of soils and growing conditions; I’ve observed many well kept privet hedges that would give boxwood a run for its money during the spring or summer. The foliage persists late into the fall often turning purple but is not evergreen. There are no serious disease or insect problems and oftentimes plants seem to thrive with neglect. Several different species and many different cultivars exist for a range of size, texture and leaf color.

Negatives: Privet (Ligustrum spp.) is not native to central Ohio and can easily spread by seed into native areas and out compete native species. They are also not evergreen.

3. Wintercreeper euonymus

Until recently I have always considered this species of euonymus to be best used as a ground cover or climber on a tree or trellis. More and more though, I’m seeing it in the landscape pruned into a very small and cute hedge or sculpted into 1 to 2 feet tall and wide mounds looking very similar to boxwood. Euonymus in general is fast growing and adaptable from full sun, to full shade, and to just about any landscape situation that isn’t a swamp. Leaves are evergreen most winters (leaf drop can occur when temps drop below -20 F) and there are dozens of cultivated varieties for leaf size and color. I’m partial to the green and white variegated cultivar ‘Emerald Gaiety.’

Negatives: Wintercreeper euonymus (Euonymus fortunei) is not native and can easily naturalize and take over unmanaged native areas. They can be susceptible to euonymus scale and difficult to treat successfully once a population is established.

4. Spirea

There are several species and dozens of different cultivars of spirea that mimic the compact and rounded habit of boxwood. They can be grown as separate plants, planted in masses or managed as a hedge. Spirea can grow in most landscape situations and will perform well in any soil that is not excessively wet. Spirea are easy to grow, have little insect or disease problems, respond well to pruning and shearing, and are cold hardy and adaptable to full sun and partial shade. Spirea are deciduous but even without leaves, the stems and twigs are so dense that the structure of the plant still provides texture and interest in the winter landscape.

Negatives: Spirea are not evergreen. They can get powdery mildew but it has little impact on the overall health of the plant. Spirea may also be somewhat overused in the landscape but for good reason - it is almost impossible to kill.

5. Japanese HollY

Japanese holly (Ilex crenata) is another compact evergreen shrub with a rounded habit and dark green foliage through the growing season and through the winter. They can grow 3 to 5 feet in height and width, although I have observed larger plants in arboreta. Japanese holly (Ilex crenata) is cold hardy to - 20 degrees Fahrenheit and adaptable to both full sun or partial shade. They respond well to pruning/shearing and can be used in hedges, foundation plantings, or in masses. Several different cultivars are available for different sizes, colors, and superior cold hardiness.

Negatives: Japanese holly (Ilex crenata) is slow growing and not tolerant of high pH soils. They are a preferred host to spider mites during extended periods of drought. Japanese holly (Ilex crenata) is not well known in Ohio and could be difficult to source. I would avoid using the upright cultivar ‘Sky pencil’ unless in a warmer protected spot with exceptionally well drained soil.

6. Globe arborvitae

Globe arborvitae (Thuja occidentalis ‘Globosa’ or ‘Little Gem’) is a compact and rounded form of our native eastern arborvitae. Its leaves are bright green in the spring and summer but turn more bronze or yellowish green during the winter months. Globosa arborvitae is a dwarf form and matures to only 5 to 6 feet tall and wide. They are very adaptable to different soil types and respond well to pruning and shearing. Globosa arborvitae can be used as a specimen plant or accent plant as well as in hedges or foundation plantings. Little gem arborvitae has essentially the same habit as globosa arborvitae but are smaller, maturing to a height of about only 3 feet tall. Either cultivar will perform well from full sun to partial shade (but they should have at least a half day of sunlight).

Negatives: Deer will eat arborvitae to bare wood when hungry. They are also a preferred host to bagworm and spider mites.

7. Yew

Yew (Taxus spp.) is a hardy and easy to grow evergreen shrub. I use them primarily for screening in the parts of my garden that receive less sun, but they can be easily manipulated and sculpted into tight hedges, mazes, and formal shapes in the same fashion that we often treat boxwood. Yew are very adaptable and urban tolerant and can withstand almost any amount of pruning. They will grow well in sun and shade and have few disease or pest problems. If they are used as an alternative to boxwood, I recommend the cultivars ‘Runyan’ or ‘Densiformis’.

Negatives: Yew are susceptible to deer browsing

8. Japanese Plum Yew 

Japanese plum yew (Cephalotaxus harringtonia) is similar to yew, but with longer and glossier needles. I have planted this in more than one rural location and my experience so far is that deer will not touch them. Japanese plum yew (Cephalotaxus harringtonia) should be considered by anyone that likes yew but has given up because of continual deer damage. There are several different cultivars selected for a range of different sizes and habits but ‘Duke Gardens’ is the cultivar I recommend for central Ohio gardens and for anyone wishing to experiment with using Japanese plum yew (Cephalotaxus harringtonia) to replace boxwood. This cultivar matures to approximately 2 to 3 feet in height, approximately 3 to 4 feet in width and is cold hardy to - 20 degree fahrenheit.  There are no serious pest or disease problems.

Negatives: Straight species is not cold hardy in true zone 5 winters (winters that reach -20 F). I observed significant winterburn in the plants in my garden from the cold snap we had just before the holiday season of 2022.

9. Inkberry 

This is one of the boxwood alternatives that I think has the most potential. Inkberry (Ilex glabra) is native to the east coastal plains of the US and is a compact evergreen shrub with lustrous, dark green leaves during the growing season. Foliage can bronze somewhat during the winter months. Without pruning, inkberry (Ilex glabra) can reach heights of 6 to 8 feet tall with a width of 8 to 10 feet wide. Female plants can produce a small, pea-sized black berry (hence the name inkberry) that is edible to birds. Inkberry (Ilex glabra) performs well from full sun to full shade (foliage density is better with at least 5 to 6 hours of sunlight) and is cold hardy to - 20 degrees fahrenheit; although I have observed winterburn in exposed plants during winters with temperatures that have dropped below zero for extended periods of time. Inkberry (Ilex glabra) responds quite well to heavy pruning or shearing and has strong regenerative growth in established plants. They can easily be used as individual specimen plants or in hedges. I recommend using the cultivars ‘Cape Cod’ or ‘Compacta’ if available. These selections maintain a more rounded and compact habit with less pruning.

Negatives: Inkberry (Ilex glabra) is not tolerant of excessively high pH soils and plants can lose lower leaves and become quite leggy if not well managed. I have observed significant deer browsing during periods of extended snow cover in landscapes with a high deer population.

10. Canadian Hemlock

Canadian hemlock (Tsuga canadensis) is one of my favorite evergreen trees. It is a native and graceful evergreen tree with glossy dark green needles that also responds well to aggressive pruning. When my wife and I moved into our current home in 2008, we planted 36 Canadian hemlock (Tsuga canadensis) on 5 foot centers around the perimeter of our front and side yards. We keep these plants sculpted into a tight 6 feet tall by 3 feet wide pyramidal shaped hedge which we prune once a year in the late spring, approximately a month after new growth has pushed out. This could make an excellent replacement for a tall boxwood hedge.

Negatives: Canadian hemlock (Tsuga canadensis) is susceptible to deer browsing during the winter months with extended periods of snow. They are a preferred host to spruce spider mites when under stress. Canadian hemlock (Tsuga canadensis) also have poor tolerance to drought.

These 10 plants are just the beginning of the conversation regarding boxwood alternatives. There are dozens of other cultivated varieties of chamaecyparis, juniper, spruce, pine, fir, leucothoe, etc that could fulfill the same niche in many of our gardens. I believe there is a perfect substitute out there for every plant. The perfect substitute for your needs will depend on your individual situation and landscape.

Why Are We "Buckeyes?"

Dear Reader,

As I sat in my family room on Friday night making buckeye necklaces for friends and family before The Ohio State University football team faced off against Penn State, I began to wonder why anyone would call themselves the “Buckeyes?”I like to think a team prefers to have a name that intimidates or even scares an opponent, but not us. Many throughout central Ohio consider themselves “Buckeyes” even if they didn’t attend The Ohio State University. However, what does it mean to be a buckeye and why is the identity of Columbus based around this unique nut from a tree? Well, there is actually quite a bit of history surrounding the Ohio buckeye tree (Aesculus glabra) in our beautiful state and the story of how it was adopted by our university may not be well known.  

[Illustration by Kenny Greer, Russell Tree Experts]

The Ohio Buckeye has palmately compound leaves, usually comprising of five (occasionally seven) leaflets. The leaves are bright green in the spring and summer, turning to yellow and gold in the fall, creating a stunning display of autumn colors. In the spring, the Ohio Buckeye produces clusters of small, tubular, greenish-yellow flowers. These flowers are a valuable nectar source for pollinators, including bees and butterflies. The most iconic feature of this tree is the nut, the name of which is thought to be derived from its resemblance to the eye of a deer or “Buck-eye.” These nuts are encased in a spiky, leathery husk that splits open in the fall to reveal the glossy, dark brown nut. While they might resemble true chestnuts, it's important to note that buckeye nuts are not edible and can be toxic if ingested.

[Illustration by Kenny Greer, Russell Tree Experts]

Early settlers used these nuts to craft buttons and the trees themselves became valuable for their wood and ornamental qualities. It didn't take long for the buckeye tree to become an integral part of American culture. The first recorded use of the term Buckeye was in 1788 to refer to a settler. Colonel Ebenezer Sproat, who happened to be large in both size and character, was aptly named Hetuck (the Indian word for buckeye) by local natives. He proudly carried the Buckeye nickname for the rest of his life and the label gradually spread to his companions and other local settlers. By the 1830s, writers were commonly referring to locals as “Buckeyes.” The Buckeye nickname became even more commonplace during the 1840 presidential campaign when Ohioan William Henry Harrison was running for president. His supporters wore buckeye-shaped wooden tokens as a sign of their allegiance, and the nickname stuck. Some even believed that carrying a buckeye nut could bring good luck similar to a rabbit’s foot or a four-leaf clover.  The buckeye continued to resonate with Ohioans and became the state tree in 1953.

The Buckeye & The Ohio State University

Learn more about the history of Brutus Buckeye
[Illustration by Kenny Greer, Russell Tree Experts]

In the early 1950s, The Ohio State University held a contest to select a new mascot. A student named Dick Doan, who was a cartoonist for the university's student newspaper, suggested the buckeye as a potential symbol because of its significance to Ohio. Prior to this, The Ohio State University hadn’t solidified any formal name. In 1950, The Ohio State officially adopted the name "Buckeyes" and became associated with the university's athletic teams and more. It wasn’t until 1965 that two students, Ray Bourhis and Sally Huber, formalized this tree nut as the official mascot that has been an iconic figure for Ohio State ever since. During this period, schools were known to bring live animal mascots to stadiums and the idea of corralling a live buck didn’t seem like the brightest idea. Instead, they delved back into our state’s historical roots and opted for the simple buckeye nut. An unnamed papier-mâché mascot inspired by the buckeye nut entered Ohio Stadium on October 30th, 1965 during a football game against Minnesota. Shortly afterwards, OSU held a contest to pick a name for the mascot which ultimately led to who we know today as Brutus Buckeye, responsible for the daunting task of rallying fans and encouraging our athletics teams!

Buckeye Grove (pictured above) at The Ohio State University, located just south of Ohio Stadium, is filled with various buckeye trees!

Today, the buckeye is a well-known symbol of The Ohio State University and the buckeye leaf logo is recognized across the country, particularly in the realm of college sports. The buckeye tree and the nuts it produces are closely associated with the state of Ohio and have become a source of pride for OSU and its fans. So next time you’re cheering on our Buckeyes, feel free to quiz those around you to see who really knows why our beloved university chose a toxic nut as a lasting symbol.

How to Plant a Balled-and-Burlapped Tree!

Dear Reader,

TJ Nagel and Mike McKee standing in front of a newly planted ginkgo tree.

My friend and colleague Mike McKee (an ISA certified arborist at Russell Tree Experts) and I were discussing recently how rarely we see a properly planted landscape tree. Every day we are out and about talking with folks who have stressed trees that are planted too deep, or that are being girdled by landscape materials or trees that are simply planted in the wrong location. Much of the tree preservation and tree removal work that we perform is a result of trees that were improperly planted. 

Russell Tree Experts does not offer tree planting services but Mike and I decided it would be valuable to write this article and make a how-to video on what we believe is the best way to plant a balled-and-burlapped tree (although much of the video can apply to trees growing in containers as well). The goal of this article and video is to empower everyone to be able to plant a tree correctly and to be able to recognize what a properly planted tree is supposed to look like. 

The following is a checklist of essential steps that should be followed when installing (or having installed by a contractor) a new balled-and-burlapped tree.

 1. Plant the Right Tree

There is a tree out there for every landscape situation. It is important that you choose wisely when you are selecting a tree for your situation. If planting in a low site that regularly experiences flooding or standing water you might consider a bald cypress, willow or sycamore, something that is water loving/tolerant. If planting in an excessively dry area you may consider a ginkgo or some type of elm. If you are planting under overhead utilities, planting a smaller statured tree such as a redbud, will likely help to avoid conflict between the lines and tree in the future. Planting the right tree in the right location is the most important step. You may follow the rest of this checklist flawlessly but if you select the wrong tree, it was all in vain. If you are uncertain of what the right tree is for your situation, it’s worth hiring an arborist for a consultation and I know a few good ones.

 2. Plant at the Right Time

Fall is for planting. Early Spring is pretty good too. Planting a new tree during either of these times while the tree is in or approaching a dormant state will improve survivability by avoiding a lot of the initial stresses trees experience during the growing season like heat and drought.

3. Tree Pruning

If a tree could only be pruned once in its life, pruning at planting is the time to do so. The overall goal of pruning at planting is to improve the structure of the canopy, to remove crossing and broken limbs, or to reduce/remove upright limbs that might be competing to be the central dominant leader. Note: It is equally important not to over prune a newly planted tree, as having the appropriate amount of leaf area in the canopy next season is essential to maintaining good health and vigor. 

 4. Locate the Tree’s Trunk Flare/Buttress Roots

The trunk flare will be found low on the main stem and should be the portion of the tree that gets wider just before ground level. Locating the trunk flare is essential for determining the depth of the hole you are about to dig for the tree.  

Two examples of root flare, which is where the trunk and roots of a tree meet.

5. Begin Digging!

Dig a hole that is 1.5 - 2 times the diameter of your root ball to allow loose soil to be backfilled around the rootball, which will be easy for new roots to penetrate. Do not dig the hole any deeper than the distance between the bottom of the root ball and the trunk flare. It is important that the trunk flare is at or slightly above grade once it has been placed in the planting hole. If the trunk flare is below grade, the tree will be planted too deep and will be more prone to stem girdling roots, reduced vigor, and will become more vulnerable to pests and disease. Important Note: Many balled-and-burlapped trees are already too deep within their own root ball. Do not assume that the top of the root ball is the trunk flare. My experience is that more often than not, I have to remove a few inches of soil from above the trunk flare at the time of planting. This can be seen in the video as well. Linked down below is my fellow coworker Chris Gill’s Arbor Ed article on stem girdling roots.

6. Stabilize the root balL

Stabilize the root ball in the hole. After the tree is standing upright in the hole, verify that it is positioned correctly (centered and upright) and add soil around the bottom six to eight inches of the root ball. Tamp the newly added soil to stabilize the root ball and tree while adjustments to the root ball are made. 

 7. Remove the twine, Top 1/3 of Burlap, and Top 1/3 of Wire Cage

Remove the twine around the trunk, remove the top third of the burlap and remove the top third (approximately) of the wire cage. The purpose of removing these materials is to prevent damage to the trunk and buttress roots as they grow over time. Removing the twine, burlap and wire cage is the subject of much debate amongst landscape contractors, tree producers, and arborists. In an effort to be brief, our recommendation to remove the top third of the wire cage, the exposed burlap (approximately the top third), and the twine is a balance between ensuring root ball stability/new tree survivability and planning for the long term health of the tree over the next hundred years. There may be some instances, like planting new evergreen trees in exposed/windy sites where it may be acceptable to leave the entire wire cage, burlap and twine intact for one full growing season before returning to remove it later.

8. Verify Tree’s PositioninG AND BEGIN BACKFILLING

Verify again that the tree is still positioned correctly. Mix a small amount of compost into the existing soil and begin backfilling the remaining portions of the hole with this mix. Lightly tamp the soil to remove air pockets but be careful not to overly compact soil as pore space is needed for water and oxygen.

Adding compost or a soil amendment to the existing soil is one way to attempt to improve soil structure and nutrient availability. Not every newly planted tree requires soil amendment. If you are planting in a native area where the soils have not been disturbed previously, you likely can backfill with just the existing soil that came from the planting site. 

9. Mulch around the tree

Apply a 1-to-2 inch tall mulch ring around the trunk of the tree that extends out to the canopy drip line.

Mulch correctly around the tree. Once the tree has been planted with the trunk flare just above ground level, it is time to add one to two inches of mulch. It is important that mulch is not over applied or mounded around the main stem. It should be applied evenly around the main stem with a small berm on the outside edge that directs water toward the tree. I generally recommend pine bark or hardwood mulch although I’ve started using pine needle mulch around trees and shrubs that like a more acidic soil. Mulch does a great job of retaining moisture around newly planted trees in addition to reducing competition from weeds, regulating soil temperatures, reducing soil compaction and adding nutrients to the soil. Linked below is my fellow coworker Lindsey Rice’s Arbor Ed article on how to mulch around a tree.

10. Water YOUR TREE

Watering a newly planted tree correctly is as important as selecting the right tree. Watering is the single most important maintenance factor in the establishment and success of planting a new tree. The best way to water a tree is slowly and deeply so that water is trickling down into the root ball of the tree and not washing away into the lawn. A newly planted balled-and-burlapped tree should be watered at the time of planting and then once a week until temperatures are consistently below freezing. Watering in this same fashion should resume when the tree breaks dormancy and leafs out the following Spring. It generally takes 2 - 3 growing seasons before a balled-and-burlapped tree is established and can fend for its own water.   Establishment could take longer with larger trees. For more information on watering, see my previous Arbor Ed article and video on how to water a tree linked down below.

11. Protect YOUR TRee!

Ginkgo biloba with deer protection.

Protect your tree from mechanical damage. This step may not be necessary for every newly planted tree. If you live in an urban area without deer and have large generous planting beds free of turf, you can likely skip this step. When planting in rural areas, I often recommend using some sort of deer protection to protect the trunk of trees until they have surpassed eight to ten inches in diameter. I like to use a 4 foot tall wire fencing cut into a 7 - 8 foot length and then wrapped around the tree. In addition to protecting the trunk, the fencing also makes it more difficult for deer to feed on lower limbs. Trunk guards or corrugated drain pipe can also work to protect tree trunks, but they must be removed before the heat and humidity of the summer. I also recommend trunk protection for folks that have trees in areas where turf is tightly managed with large and fast moving mowers and string trimmers.

12. ENJOY!

Your new tree is now planted! Enjoy it! If there are any tags on the tree, you can remove them now if you have not done so already. I hope you enjoyed this article and the video below. Please reach out if you have any questions, happy planting!

The Year of the Ugly Boxwood

Dear Reader, 

My good friend and arborist colleague Cat Baumgartner wrote the below article for the Inniswood Garden Society’s quarterly member newsletter (known as The Image). As soon as I read it, I knew that I wanted to share it with all our readers. Cat does a thorough job of describing the most serious problems we have had with boxwood this year and she explains them well and in simple terms. She has generously agreed to let us republish it.

The Year of The
Ugly Boxwood

by cat Baumgartner, Oakland Nursery

I don’t have a simple answer. Or there are multiple answers, and your boxwood might have one, or several of the problems at once.

I’ll go over the likely suspects for this year- including winter damage, or ‘winter burn’, Boxwood Leafminer, Volutella Blight, and THE Boxwood Blight.

I’ll start with winter burn. Boxwood store a lot of their energy in their leaves through the winter. When we get extreme cold and wind in the winter, the leaves will lose more moisture. If the ground is frozen or dry (or worse, both), the leaves lose moisture faster than the roots can replace it, and we get the ‘burn’, where they turn a straw color and die, staying attached to the stem. It wasn’t noticeable until early spring, because evergreens have a delayed reaction to stress. It’s why we can cut down trees for Christmas and they don’t immediately turn brown, often lasting months. We did have greater than normal rainfall last year, but the three months leading up to late December were on the dry side. So, the ground was dry leading up to the extreme cold event that hit in late December creating a Double Whammy. There was a lot more winter burn this spring than I’ve seen in decades. It looks like straw-colored sections in the shrubs, often in a random pattern.

Next, there are different blights out there that can affect boxwood. ‘Blight’ is a general term for a plant disease, typically caused by a type of fungus. Most of them are less common and less damaging than the blight striking fear in the hearts of gardeners that is Calonectria pseudonaviculata, called simply “Boxwood Blight”. There have been some isolated cases in the Greater Columbus area. The main symptom though is defoliation. You’ll have green leaves, then they’ll start looking funny, and rapidly progress and fall off the stem. In a matter of weeks, you can go from a healthy-looking plant to one with sections with completely naked stems. Definitive identification requires lab testing. Other blights can show similar symptoms, but since some are more treatable, confirming which type of blight your boxwood might have is recommended before removing plants. If you do have “Boxwood Blight,” replanting with more boxwood is not recommended, so confirmation of what kind of blight you have will also tell you what you can plant in that spot. Most of the damage we’ve been seeing is NOT “Boxwood Blight.”

Volutella Blight or Pseudonectria Canker (Pseudonectria buxi) can be damaging but is not necessarily a death sentence often just affecting individual stems and not whole portions of the plant. Symptoms can be seen if the stem is sliced into, showing dark brown streaking just under the bark. Most twigs infected with Volutella blight will turn straw colored and die. In most cases dead stems from Volutella canker can be easily pruned out and the remaining portions of the boxwood will fill in slowly over time. 

This year we also had frost damage in May. If leaf buds are still tight, frost is not a problem. If the new leaves have emerged, but have ‘hardened off’, it is also not a problem. But if the new growth is timed so that it is new, fresh and tender, and then we have a late freeze, the new growth is damaged, turns that sad straw color, and is aesthetically at least, a problem. A healthy shrub can put out another round of growth, and it is not a long-term problem. Trimming off the burnt new growth is all that needs doing.

Boxwood Leafminer, an insect pest, is an ongoing problem. The damage from leaf miner is more generalized, an ‘all-over’ bad look rather than the chunky sections dying back. The adults lay eggs in the new growth in mid-spring, and as the larval stage hatches and begins to feed on the interior tissues, the leaves start looking bad, often having a blistered or bubbled effect, usually easier to see from the bottom of the leaf.   

Preventative sprays can thwart adult leafminers from laying eggs in the new growth, but need to be applied as you see the new growth. Systemics applied in the Fall or Spring can also provide control but know that boxwoods are insect pollinated. 

If you don’t have Boxwood blight, you have two options. Cut out the dead branches and let the plants regrow which may take three years or more to totally restore, in good condition, or replace the plants.

A Final Note…

Since Cat wrote her article, we have had several boxwood shrubs test positive for yet another disease, Colletotrichum theobromicola (also referred to as boxwood dieback). This is a new disease for central Ohio and symptoms look similar to other blight diseases with the random dieback of twigs and straw-colored foliage. However, in addition to twig dieback, the pathogen also causes leaf spots that appear white in the center surrounded by dark brown margins as well as a bright black discoloration just beneath the bark along the twigs. The jury is still out on the best way to attempt to manage this disease but for now, good cultural practices such as removing symptomatic plants and sterilizing pruning tools between pruning different plants are the best-known strategies. Fungicides might also be helpful, but efficacy has not been determined. Laboratory testing should be used to confirm boxwood dieback because it can easily be misdiagnosed as other blight diseases.

As we continue to have more problems in the landscape with boxwood, it may be time to consider alternative plants that can achieve a similar function. Stay tuned for my boxwood replacement article later this Fall.

Anatomical Upgrades for Your Trees!

When you think of anatomy, what comes to mind? I think of humans specifically, and learning about the wonderful bone and organ systems in our body in middle school science class. You may think about the anatomy of various animals and how there is an abundance of variety depending on where you are in the world, but how often do we consider the anatomy of trees?

Surely trees are just trees, right? They grow without us even considering how or why they may grow in the ways that they do. We may be blissfully unaware of their anatomy or structure until we are confronted by the reality of a winter ice storm or a summer thunderstorm. Oftentimes, we may find trees with less-than-desirable structure having taken damage after these events, or worse, having caused property damage along with their own demise!

Two examples of trees with codominant stems

You may be asking yourself, what does poor tree anatomy look like? The answer to that question deserves its own article, however a majority of tree structural problems can be narrowed down to codominance, and that is what I want to address in this article. Codominance is when a tree has two or more similarly-sized trunks emerging from the same location and forming a distinct “V” shaped union. There are varying reasons as to why a tree may be codominant, and some species have natural habits that lend themselves to becoming codominant. 

Visual representation of codominance by Jacob Nau

To give you a visual representation of codominance, bring your elbows together in front of your chest, with your palms facing you. Now, spread your wrists apart, keeping your elbows together to form a distinctive V shape. Opening up your fingers you can picture the crown of a tree. Seems like an awkward, weak position to be in, right? Now, imagine adding the weight of tree branches, leaves, rain and 15-50 mph wind gusts, etc. (trees can go through a lot!), while you strain to keep your elbows together, and you can begin to imagine why a codominant union (V-shaped union) in a tree is not anatomically advantageous.

So what can be done to fix, or even prevent, codominant structure in a tree? The answer to this question largely depends on the age of the tree. If your tree is young and generally under the age of approximately 20 years, then a structural pruning plan can be performed to help guide the tree out of its codominance over the next 5-10 years. 

However, if your tree is large and mature, there are a number of services that can be used to help support your tree's anatomy. Those services include:

End-Weight Reductions

• Reduce the length of long, lateral branches in the tree’s crown to reduce the weight and levering effect on the codominant union below. Typically performed before or with a cabling support system.

Cabling Support System

• Install a single, or multiple, static steel cable(s), or dynamic rope cable(s) in the tree’s crown to support the codominant union below.

Through-Brace Support System

• Install a system of steel threaded rods into the codominant union to strengthen that area of the trunk. This is usually performed in-tandem with a cabling support system.

Propping Support System

• Install a single, or multiple, semi-permanent wood prop(s) to support a lower, large lateral limb to ease the strain on a codominant union. This is a more unique way to support the tree's anatomy, specifically for low, long, and lateral limbs that are difficult to support with a cabling system.

All of the services listed above, including the young-tree structural pruning, are services we perform at Russell Tree Experts. I highly encourage you to look out your window and consider your tree's anatomy! Can they be supported? Is it time for an anatomical upgrade? If so, give our local office a call at (614) 895-7000 and we will happily connect you with one of our Regional Managers to assist you in determining the best course of action for your trees!

3 Knots for Your Backyard!

What uses come to mind when you think of knot-tying? Putting up a rope swing, securing a load in a truck bed, or installing a makeshift fence around the garden perhaps?

Rope handling and knot-tying may be overlooked by many today as an antiquated skill lost to history. When questioned, most people may only think about knot-tying and rope handling as a badge that is to be awarded to young Boy or Girl Scouts. 

Or, if you are an avid history aficionado like myself, knot-tying may even conjure up images in your mind of the seafaring sixteenth and seventeenth centuries. The age of sail was one of the pinnacles of human technology with navigating the oceans on massive wooden ships. Skilled crews used miles of rigging consisting of ropes and knots to help steer the large vessel.

The rigging for a British ship-of-the-line.

All of these scenarios are just a brief glimpse into how interwoven human history is with knot-tying and the use of rope. Some historians even believe that knot-tying and rope handling is a technology older than the wheel. It is a relationship as old as recorded history itself! 

In a world full of technological advancements and mechanical wonders, you won’t be able to find a replacement for good knot know-how and rope handling. Just think of some of the industries we wouldn’t have without them: rope access, technical rescue, arboriculture, commercial trucking and shipping, commercial fishing, performing arts, the list goes on and on!

Let’s take a look at three knots that you may find useful in your own backyard or around the house. I will let the videos speak for themselves on how to tie the knot, but I will include some common uses down below!

Figure Eight Stopper Knot

The figure eight stopper knot is a relatively easy knot to tie and functions as the name implies. Tying this knot on the end of a rope may prevent it from slipping out of your hand or falling out of your reach. The figure eight knot is the building block of a whole range of more knots relating to or requiring the figure eight knot!

Tying a number of these knots about a foot apart from each other on an anchored rope will give your kids a simple way to climb a rope. Using a short section of 2x6 wood with two equally spaced holes, two equally-long pieces of rope, and two figure eight stopper knots, you can have yourself an affordable rope swing!

But how do we anchor our rope swing?

Bowline Knot

This particular knot forms a secured loop at the end of a rope that can be used to attach the rope to a suitable anchor. Commonly referred to as the “king of knots”, this knot is also the building block of a whole family of bowline-related knots. It may be more difficult to tie than our figure eight stopper knot, but this is a very appropriate knot to use for anchoring our rope swing as well as anchoring a rope to a truck bed or trailer when you are trying to secure a load,

Chain Sinnet (Daisy Chain)

This knot is used primarily for shortening or storing a longer rope and having quick access to all of its length, without the hassle of coiling or tangled, unwanted knots! I use this knot extensively to store longer extension cords in my garage so that I can plug them in and then transport them to where I need them on my property without having to deal with a tangled, jumbled up mess.

BONUS Knot: Slipknot

If you have mastered the chain sinnet, then you may have learned a fourth knot without even realizing it! The chain sinnet is started by tying a Slipknot. We have our arborists first learn this knot when they begin working at Russell Tree Experts. It is an easy, quick knot to learn and allows you to add a loop anywhere along the rope. To retain the loop in the rope, be sure to clip a carabiner or some sort of equipment to the loop. We use this knot daily to send equipment into a tree’s crown. You may find a use for it such as when adjusting the height of a hammock!

I hope this article has inspired you to look into how tying knots can improve your day-to-day activities around the house. Cheers to the craft of knot-tying!

Magnolia Scale: They're Back!

By Mike McKee
ISA Certified Arborist®
June 20, 2024​

Hello! We have decided to revisit the topic of magnolia scale and add more information to this previously published article as we are in the middle of a larger magnolia scale infestation compared to last year (2023).

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Please note: This article was originally published on 8/9/2023 and was revised and republished on 6/20/2024.

Is your magnolia tree turning black? Is it attracting ants, flies, bees and wasps? Is there a sticky substance covering the leaves and everything under the plant? If you look closely, you will also see white blotches on the twigs throughout the tree.

This is an invasion of magnolia scale like we have not seen in several years. They happen to thrive in warm summers with abundant moisture. The population is building and is very apparent this year.

The insect overwinters on twigs and is inconspicuous to the untrained eye until it starts feeding and producing honeydew. Honeydew is the very sweet, sticky substance secreted by the insect that in turn coats the leaves and anything under the plant. This is what attracts other insects to the plant. Eventually the insect covers itself with a waxy coating that protects it while feeding. These are the white blotches we are now seeing on the plants starting early summer through August.

Nymphs emerging from a recently plucked adult Magnolia Scale

The juvenile stage of magnolia scale emerges from these waxy coatings (the adults) in mid to late August through September as crawlers. This is when scale are most vulnerable to insecticides and we attempt to control their population. We typically recommend 2 to 3 topical insecticide sprays during this period spaced a couple weeks apart for the best control of the insect due to the extended emergence. During seasons with larger infestations, it is unlikely that insecticide sprays will completely eliminate this insect. The overall goal of plant healthcare is to keep the population at a threshold that minimizes damage and maintains aesthetics of the host tree.

If the tree’s owner is concerned about the population of magnolia scale before the appropriate window for insecticide applications is open, there are a few DIY options that can be done. First, the insects can be scrubbed off from branches and leaves in June and July. This is when the adults are visible before the hatch begins. You could also prune out heavily infested Interior branches to help reduce numbers. Be sure to completely dispose of any pruned branches as the insect will still hatch. Spraying the trees with a medium pressure garden hose can also eliminate some insects as well as reduce the honeydew on the plants.

The insects feed by sucking sap out of the tree. If left untreated the scale population can grow to levels that will cause decline and eventual death in your tree.

Another issue with Magnolia scale is the occurrence of sooty mold which is a byproduct of the honeydew produced by the scale. It is a black fungal growth which is what most people notice first. Although this generally does not harm the tree, it is very unsightly.

In closing, if you have a magnolia in the landscape, give us a call and we will dispatch a certified arborist to your property to come out and complete an evaluation of the tree and make recommendations for the best management strategy. Timing is everything.

How to Plant a Tree

Dear Reader,

Today I would like to discuss step-by-step how Board Certified Master Arborist TJ Nagel plants a tree! He very kindly planted a kwanzan cherry tree for me at my house that was donated by him, Cindy, one of our office managers, and Mark, our fleet manager! At the bottom of this article is a YouTube video where you can visually follow along!

THE STEPS

1. First, pick out a tree! TJ and I went to Oakland Nursery and selected a kwanzan cherry tree. To help in the planting process, we brought mushroom compost, mulch, a trowel, a shovel, and a pickaxe. Mushroom compost will help enrich the soil. Mulch will help with water retention, temperature regulation, protection from lawn mowers, and curb appeal. A trowel, a shovel, and a pickaxe will help in the digging process.

2. Choose a tree planting site! We chose in front a picture window in the front yard for viewing pleasure and as it was a few feet away from any obstructions such as my neighbor’s driveway, the sidewalk, my front porch steps, and nearby plants. We also knew that we were not planting directly on top of any pipes or water lines.

3. Dig your hole! The hole should be slightly wider but just a few inches shallower than the size of the tree’s pot. You will want a couple extra inches around the circumference of the root ball to pack in compost and dirt. We also like to plant most trees a few inches above the surrounding ground level as the tree could settle over the next couple of years, which is why the hole can be a few inches shallower than the depth of the root ball.

4. Take the tree out from the pot and cut 4 straight lines across the root ball. This will break up and loosen both the dirt and roots which will help minimize the risk of stem girdling roots. Optionally, you can also clean up and remove any small or entangled surface roots.

5. Test fit your tree and check if the hole’s depth is adequate. As mentioned earlier, you will want a few extra inches of space around the circumference of the tree and you will want the tree to sit a few inches above the surrounding ground level. Make adjustments to your hole if needed.

6. Mix up the mushroom compost with the existing, dug up soil with an approximate 1:1 ratio to help enrich the soil and promote growth. You can break up any chunks of dirt to obtain a fine, well blended mixture. If a few grass blades end up in the mixture, it is okay as it will decompose and help enrich the soil with nutrients. As long as there is no significant sod or roots on the surface, there should be no significant risk of weeds. To further minimize the risk of weeds and for aesthetic purposes, we will be placing mulch over top of the soil.

7. Place your tree in the the hole and fill it with your blended soil mixture! Be sure to keep your tree straight and upright while filling in your hole. You will want to lightly compact the soil mixture so that way the tree is stable during windy weather and does not lean or fall over.

8. Water the soil!

9. Apply a couple inches of mulch on top of the soil! Keep the trunk exposed and not covered with soil and also avoid creating a mulch volcano in order to minimize the risk of stem girdling roots. We shaped a small, subtle and almost unnoticeable moat around the perimeter of the elevated soil level to help water flow and soak towards the trunk.

10. Water the mulch!

11. And voila, your tree is now planted! Or in this case, this beautiful kwanzan cherry tree is now planted! If there are any tags on the tree, you can remove them now if you have not done so already. Optionally, TJ also made a few minor pruning cuts but this is not always necessary.

The first year is vital for a newly planted tree’s survival so make sure that it does not lean over, that it does not get chewed on or rubbed by any animals like deer, and that it gets properly watered, which can be once to twice per week depending on the season, your local climate, and the way the tree is packaged. You can optionally use a tree trunk guard or posts to help protect your tree and keep it straight but it may not be necessary depending on where you live.

I personally would like to give the hugest shoutout to TJ, Cindy, and Mark for donating and planting this tree. Earlier this year, my sister passed away and she loves kwanzan cherry trees. She loves their spring colors, has posters and images of them in her room and on her phone, and uses the Japanese cherry blossom scent for all her Bath & Body Works products. This sentiment is incredibly touching and meaningful and I cannot be more appreciative.

As mentioned earlier, linked down below is a step-by-step YouTube video you can follow along with as well as a few related tree planting articles! Hopefully you found this article educational and entertaining!

How to Mulch Around a Tree

Dear Readers,

Mulching is an important aspect of tree maintenance that is both functional and decorative, adding to your tree’s lifespan and helping it look its best. The main benefits of tree mulching are that it deters weeds, improves soil quality, protects trees from lawnmower damage, insulates soil from extreme temperatures, and retains moisture during hot weather. Today, I would like to talk about some tips and tricks on how to properly mulch a tree. At the top of this article is an instructional video hosted by ISA Certified Arborist Lindsey Rice that can be used to follow along while mulching your own tree!

Example of a properly mulched tree

To mulch a tree, you will need organic wood chip mulch, a shovel, a rake, and personal protective equipment such as safety glasses, gloves, and boots. A wheelbarrow or air spade may potentially be needed depending on the situation. The best time to mulch a tree is in the fall or spring. Many trees are incorrectly mulched when the mulch is too high or when it covers the root collar of the tree, which is where the trunk and roots meet. The mulch only needs to be 1 to 2 inches deep and the root collar should be completely exposed in order to properly receive oxygen. This will help prevent girdling roots, which are roots that wrap around the trunk in search of oxygen. This can suffocate a tree and add unnecessary stress. If your tree has girdling roots or a mulch volcano, you will need to resolve these issues prior to mulching.

Example of a “mulch volcano”

Example of girdling roots

If there are no girdling roots, the first step is to pull out any weeds surrounding the base of the tree. Then, you may begin applying mulch in a wide and evenly spread area. For younger trees, it is ideal to mulch all the way out to the canopy drip line, which is where the majority of a tree’s roots extend, but you may have to compromise depending on your landscape.

Example of a canopy drip line

For older trees, this is not as important. You should still see similar results when bringing the mulch out about 3 to 5 feet from the base. You can use a rake, shovel, or your hands to evenly distribute the mulch. The mulch only has to be about 1 to 2 inches deep at most, so make sure you avoid mounding, Leave about 2 to 3 inches of space between the mulch and the root collar in order for the tree to properly receive oxygen and to prevent girdling roots. This will also help prevent any moisture issues, which can lead to disease and rotting. Afterwards, you are all set!

For maintenance, water your mulch whenever it looks dry. Ohio can have inconsistent weather, so there is no need to water it on a scheduled basis. Also, only add mulch whenever it is looking sparse and below that 1 to 2 inch needed depth. Make sure you break up, turn over, and mix in the old mulch to prolong the mulch’s lifespan, prevent any clumping, and to allow maximum movement of oxygen and water. If there are any questions, please feel free to leave them in the comments section below and be sure to watch ISA Certified Arborist Lindsey Rice’s video for a visual guide on this topic! Good luck on your next mulching project!

How to Verify a Certified Arborist Credential

Recently, it was brought to my attention that there are some people performing tree work in the area claiming to be “certified arborists” when in fact, they are not. So… how can you tell if someone is telling the truth? One way is to ask for a business card or ask for their ISA Certified Arborist® credential number which will be in the following format: [state abbreviation] – [four digits] [letter]. Here is an example of a business card (mine!) with the credential number explicitly listed:

The best way to verify this credential number is to search on the ISA Certified Arborist® database. Simply go to treesaregood.org, click the “Find an Arborist” section then choose “Verify a Credential.” From there, enter the credential certification number and submit the request to see if the credential is in fact genuine.

Over my time working at Russell Tree Experts, I’ve sadly heard countless stories of “door knockers” coming by a person’s home and ruining their beloved tree. It’s a very sad occurrence in our industry and we hope through education these stories can lessen.

Improper tree work not only can cause irreparable damage to the tree or property, but there is also potential for spreading disease to nearby trees and affecting others’ landscapes. Tree care can also be very dangerous work, for both the property owner and the person doing the work. We highly recommend hiring an ISA Certified professional (even if it’s not us!) with the proper equipment, knowledge, and experience to perform your challenging tree work. The health of our environment relies on proper care for our trees so we may enjoy their countless benefits from improving air quality to providing homes for wildlife and beyond!

We’re very proud to have 19 ISA Certified Arborists® on our staff! Feel free to double-check their credentials at treesaregood.org! :)
