Keep Informed About Trees
Ross Tree believes in educating its customers about tree and plant healthcare. Our general manager, an ISA-certified arborist, has over 30 video blogs on YouTube. Homeowners use the Ross Tree Insect Calendar to identify pests munching on their yard trees. We have posted over 80 blogs about trees on our website since 2019. Ross Tree sends out a quarterly email newsletter to its customers.
Golden Tree Programs
Trees are a significant part of Golden’s urban environment, providing beauty, shade, and ambiance. The Golden Forestry Department plants and maintains the trees in city parks, public right-of-ways, and other public spaces. Click here for more information about the Golden’s tree programs.
Emerald Ash Borer
As of August 2025, Golden has no Emerald Ash Borer (EAB) official confirmations, but it has been detected in nearby communities like Lakewood, Arvada, and Denver. Hence, it poses a current and future threat to Golden’s Ash trees. The time to act is now because Ash have no immunity to the EAB. 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.
Golden 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.

Golden Frequently Asked Questions
Who is responsible for the tree between the sidewalk and the street?
In Golden, trees in the public right-of-way are generally managed by the city. Check with Golden’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?
As of August 2025, Golden has no official emerald ash borer confirmations, but the beetle has been detected in nearby communities like Lakewood, Arvada, and Denver. 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?

Dutch Elm Disease Discovered Again
In Denver, about a hundred years ago, the City and homeowners planted approximately 100,000 American Elms, making them and the Silver Maple the most favored and numerous shade trees. The disease first appeared in Colorado in 1948 and then died out. However, it reappeared in 1968 and killed most American elms in the City, but not all of them. The disease reappeared in 2023.
Elm Leaf Pests Handbook
Elms growing in Denver need additional attention. Golden has Elm leave pests that feed on elm leaves, causing them to dry up and die. Heavily infested trees are unsightly with brown and skeletonized leaves. Repeated injuries weaken trees and make them prone to branch dieback and wind injury.
