Commerce City Tree Programs
Trees are a significant part of Commerce City’s urban environment, providing beauty, shade, and ambiance. Click here for more information about the city of Commerce City’s tree programs.
Emerald Ash Borer
Property owners are generally responsible for managing and treating the ash trees on their own property. Check out the Ross Tree EAB Handbook to understand your treatment options.
Tri-Level Fertilization Program
Ross Tree started its popular Tri-Level Fertilization Program in 2024. We use proprietary feeding formulations to help trees flourish in Denver’s arid climate and poor soils. The program has three feedings per year rather than two.
Commerce City Tree Services
We work in the order that usually serves a tree best: health first, then pruning, then removal.
Plant Health Care
Our arborists diagnose pests, disease, and soil problems, then treat them. That includes emerald ash borer treatment, systemic injections, and deep root feeding.
Tree Pruning
Standards-based pruning removes deadwood, reduces risk, and keeps the tree’s structure sound without over-cutting it.
Tree Removal
When a tree is dead, hazardous, or too far gone to save, we remove it, including large trees near homes. We handle street closure permitting when a job needs it.

Commerce City Frequently Asked Questions
Who is responsible for the tree between the sidewalk and the street?
In Commerce City, trees in the public right-of-way are generally managed by the city. Check with Commerce City’s forestry or public works staff before pruning or removing one, and call us if you want an arborist’s opinion on its health first.
Should I treat or remove my ash tree?
Emerald ash borer is present across the Denver metro area. Ash trees that still have a mostly full canopy can usually be saved with treatment. Trees that have already lost much of their canopy are usually better removed. Our arborist can tell you which applies on a complimentary visit. The Ross Tree EAB Handbook explains your options.
Are you licensed and insured?
Yes. Ross Tree is licensed, insured, and BBB A+ rated, with two ISA-certified arborists on staff. Our guide on how to choose a tree service lists what to check with any company.

Leading Innovator in Tree Insect Control
Ross Tree is the first tree company to offer systemic insecticide treatments for tree borers, beetles, aphids, and scales in the late 1990s. Trunk injections ensure that only the tree gets the product, not the surrounding environment. However, spraying is sometimes warranted for insect infestations that need immediate treatment.
Summer Tree Care Tips
Summer is an excellent time to get your trees ready to withstand Denver’s unpredictable weather. Ross Tree recommends deep rooting feeding at least two times during the growing season. Proper tree pruning forms a dominant leader and thins out the crown to withstand mechanical breakage from snow and wind.
