INTEGRITY IN ACTION
Highlands Ranch Plant Healthcare Company
Serving Highlands Ranch since 1978.
Ross Tree Company, a long-standing name in Highlands Ranch tree care since 1978, has undergone a significant evolution, transitioning from a general tree service business to a specialized plant healthcare company. Our shift represents a fundamental change in philosophy to proactive health and prevention rather than reactive tree services like pruning and removal. We are a licensed tree company with a strong relationship with the Highlands Ranch Forester Office, with a reputation for handling complex tree jobs, street closure permitting, and pioneering systemic injections to control tree insects. We strongly embrace standards-based pruning practices, which save our customers money in the long term. Why not call a licensed, insured, trusted tree and plant healthcare company with an A+ BBB rating? For convenience, we accept all major credit cards.

Emerald Ash Borer
Unfortunately, the dreaded Emerald Ash Borer (EAB) arrived in Arvada in 2020, and the beetle continues to spread throughout the City. Untreated trees are starting to show signs of EAB damage and will most likely require removal. Arvada’s forester expects all property owners to manage and treat their Ash yard trees. Check out the Ross Tree EAB Handbook to understand your treatment options.
Tri-Level Fertilization Program
Ross Tree’s 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.
What To Do After Planting A New Tree?
Wondering what to do after planting a new tree? Below are some tips after the tree is in the ground. Trees beautify our neighborhoods, improve air and water quality, enhance property values, and lower utility costs. The following newly planted tree care tips will keep them healthy.
Evergreen Tree Care
Evergreen trees and shrubs are an excellent option for any yard because they need less maintenance than many leafed trees, provide color all year long, give privacy, and are hardy. However, coniferous trees require different care than deciduous varieties.
Ross Tree is a locally owned and licensed Denver tree company that has been in business since 1978. We offer proactive tree pruning, tree insect control, and plant health care services. Why not call a licensed, insured, trusted tree company with an A+ BBB rating?
