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.
Parker Tree Programs
The tree resources and open space areas have been significant in defining the beauty of Parker. The Town takes great pride in the ability to offer this amenity to citizens. Click here for more information about the city of Parker’s tree programs.
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.
Parker 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.

Parker Frequently Asked Questions
Who is responsible for the tree between the sidewalk and the street?
In Parker, trees in the public right-of-way are generally managed by the town. Check with Parker’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.

Tree Risk Assessment
An experienced ISA-certified arborist with sound technical knowledge and experience can provide tree risk assessments for problem trees to prevent injuries and property damage. Tree risk assessments should not assume every tree defect is a hazard but consider the potential for harm from tree failure. Their job is to quantify and explain the risk so decision-makers can balance safety with the tree’s value.
Large Tree Service Job Handbook
For over 30 years, Ross Tree has been the go-to tree service company for complicated large tree removal jobs. Removing trees next to homes, garages, and fence structures requires specialized skills and equipment. If the work is near a busy street, permits may be needed for a full or partial street closure.
