Seventeen years ago near this season I was starting my second year as an arborist in training. A few months more into the year and I would be applying to the ISA to sit for the Certified Arborist examination, which thankfully I would pass. At this point in my career, I was fortunate to be working under a foreman who was (and is) passionate about trees, so as I learned primarily about climbing and pruning, I was also being taught about CODIT, tree identification, and common tree pests and diseases.
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.
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! :)

Lecanium Scale (Part Two)
Lecanium Scale (Part One)
If “Lecanium” is a new word for you, consider yourself lucky, or at worst, blissfully ignorant. If you have experienced species of this genus in your landscape you may know how devastating, unsightly, and generally… uncomfortable this insect can be. If you have ever stood under a tree covered in a scale population which is actively feeding and digesting you will know why the word “uncomfortable” came to mind. In this installment I will briefly describe Lecanium scale and its life cycle. In the next installment, I will share an unusual finding from last season, and stand out on a limb to make a forecast for this season.
♥ Happy Valentine's Day! ♥
Don’t you miss handing out Valentine’s Day cards at school? Did you make the shoe box and hope to get a card from that special someone? We’re feeling a little nostalgic this year so we decided to create some tree-inspired mini Valentine’s Day cards. You may not be in grade school anymore but take a moment and feel like a kid again by printing our Valentine’s Day cards below and give ‘em to your special someone!
Where’s the Fruit?
As an arborist, I often feel like I need to double as a detective. Trees, obviously, cannot tell us verbally how they are "feeling" or why they are behaving in a certain way. We have to look for clues as to what is possibly going on with them. When I am asked why a tree is performing poorly, oftentimes I need to swap out my helmet for a Sherlock Holmes cap and start digging around, asking questions of the tree's caretaker and standing back to observe the environment in which the tree exists.
Planting Trees for a Purpose
I think we all can agree that our TREE FOR A TREE® program is an awesome idea for replacing the trees that we remove, but as I set in the office watching nature happen outside my window, I started thinking of other reasons to plant trees. Trees provide countless benefits to our environment as well as providing food and shelter for a number of living organisms. Anytime that I am walking through a property I cannot help but notice the birds enjoying all that the trees are providing for them. I decided to write about planting trees that provide shelter and food for birds throughout the year.
Understanding Conifers
Understanding conifers should begin with a few simple definitions to clarify and classify. A conifer is a plant that bears its seeds in cones. When we hear the word cone, we likely think of pine and spruce trees, two types of coniferous trees that are widely found throughout Central Ohio and beyond. Their cones are obvious when they fall and scatter on the ground surrounding the tree. But did you know that yews (Taxus) and junipers are also conifers?
Putting the Year to Sleep
Today the light begins to increase again; days begin to lengthen. For the last 6 months or so each day has lost a minute or two of daylight, growing shorter as this part of the world approached the darkest day of the year. Earlier this week I was reading the musings of Henry David Thoreau once again, and came across a passage about the wonders of a milkweed seed, how each seed is carefully packed within its “light chest” attached to silk streamers, to be released when the time is right. Thoreau ends the thought with a quiet reflection on the faith of a milkweed plant which “matures its seeds” despite the prophecies of some men that the world would end.
How do you become a Certified Arborist?
Have you ever wanted to become a Certified Arborist? The first step is developing an interest in trees: species, habits, ideal growing conditions, diseases, pests, structure, life cycle. An inquisitive mind is a great asset for any arborist. Any question about trees is a good question! Now that your curiosity is piqued, the next step in developing your arboreal skills is finding the answers!
Free Trees! (Update: ALL GONE!)
5000 Trees Planted in One Day!
Last Friday all of our employees took the day off from their normal duties and came together to plant 5,000 trees at Pickerington Ponds Metro Park for our TREE FOR A TREE® program! The initial idea of this program was simple, plant a tree for every tree that we remove — Flash forward almost 3 years and we are very happy to see this program continue to grow as we have now planted over 12,000 trees at 16 different sites in central Ohio.
Leave Those Leaves!
Of all of our seasons, I’ve heard more people proclaim their love of fall than any of the others. It marks an end to the uncomfortable heat of summer and traditionally represents a time when we reap the gifts of the harvest and prepare for winter. And for several weeks, our trees also gift us with a wonderful display of color. Everyone has a favorite - the brilliant orange of our native sugar maples, the rich yellow of the non-native maidenhair tree (Ginkgo), the reds, purples, and browns of oaks.
What's Going on with My Oak? Part 2
Earlier this year, we shared an article that highlighted two issues that were tied to recent weather patterns and had many homeowners concerned about their oak trees - one was an insect (Oak Shothole Leafminer) and another was a fungal pathogen (Oak Anthracnose). Combined, they made for unsightly leaves that were riddled with holes and brown patches. Fortunately, both issues were more of an aesthetic concern than anything else, and neither of them required treatment or had any lasting effects on the overall health of the trees. In fact, they are both likely to occur each year to some degree and should not be reason for concern.
