I'm fortunate to have a partner that loves trees as much as I do. When I met Annette working in the nursery industry twenty-ish years ago I just thought she was cute, she made me laugh and I admired the way she helped people and animals. Over the years, Annette and I have worked together in various gardens, we have spoken together at gardening events, cared for the same clients and we have both become professional arborists. We share a passion for the outdoors, seeing new trees in new places and collecting new plants for our garden when we discover them. In short, she gets me.
Through her gardening and consulting business, Annette has always proudly promoted responsible tree care and the work that Russell Tree Experts performs. When an opportunity came up this Spring to hire a seasonal Tree Wellness technician, I (somewhat jokingly) suggested that she apply and see things from the other side. She got the position and we got to work together once again! Over the last four months our dinner chats and evening conversations have been filled with observations, debate and education. Listening to her learn the industry was nostalgic and reminded of why I got into the tree care industry. Annette is back to running her own business again but she will always be a part of Russell Tree Experts. Here are a few things she wanted every client to know - written in her own words.
1. Mulch Madness!
Don't smother your plants. In no less than 90% of the yards I visited, mulch was overdone—especially around the base of trees and shrubs. While mulch has its benefits, piling it too high can actually harm your plants.
Here's why: the root flare—the area where the trunk meets the roots—needs air and water to function properly. When mulch is too thick or pressed against the base, roots may grow upward into the mulch in search of oxygen and moisture. This can prevent them from accessing nutrients in the soil, leading to common problems like chlorosis (yellowing leaves), less vigor. Please don't forget this is important
with shrubs as well.
A visual tip: If a tree looks like a telephone pole going into the ground, it's a sign the root flare is buried—and that's worth checking.

2. Not All Fertilizers Are Created Equal
One thing that stood out to me was the quality of the fertilizer used by RTE. Unlike synthetic fertilizers that are heavy in quick-release nitrogen (which can cause fast, weak growth that attracts pests), RTE uses their own naturally composted blend. This organic fertilizer acts more like a soil conditioner—enriching the soil with beneficial microbes, improving its structure, and helping roots absorb nutrients more efficiently. It's a smarter, long-term approach to plant health.

3. A Culture That Cares (About Plants and People)
Even after moving on from the role, I still think about how impressed I am with RTE's company culture. From top leadership and gifted mechanics to the crews in the field, the commitment to doing things right was clear.
Each week, the team holds mandatory "tailgate meetings" focused on safety, plant science, the latest climbing techniques and equipment care—something I haven't seen elsewhere in my 35 years of working in horticulture. I'm not in the habit of suggesting to someone to switch companies if they are already happy with the relationship they have with their current tree company, but my third tip is that I am even more confident referring RTE after working on the inside to homeowners or someone who wants a cool career in tree work than I already was as an observer. It is important to choose a tree company who cares about safety and determining the best method of care for the health and vigor of your trees. I'm also grateful to have a platform on which to share my observations.
And yes, I was genuinely proud to drive around in that beautifully wrapped truck with the crabapple blossoms and have so many opportunities to speak with many of you.
