INTEGRITY IN ACTION
Broomfield Plant Healthcare Company
Serving Broomfield since 1978.
Ross Tree Company, a long-standing name in Broomfield 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 Broomfield 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.

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.
Broomfield Tree Programs
The City has 160 species of trees growing in Broomfield’s parks, greenbelts, and open spaces. Trees are a significant part of Broomfield’s urban environment, providing beauty, shade, and ambiance. Click here for more information about the City of Broomfield’s tree programs.
Emerald Ash Borer
Unfortunately, the dreaded Emerald Ash Borer (EAB) arrived in Broomfield in 2019, 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. Broomfield’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.

Large Job Expertise
Ross Tree Company has the staff, equipment, and expertise to remove Broomfield’s largest trees. We are known for our ability to handle jobs next to busy streets and to pull road closure permits efficiently

Tree Insect Control
Ross Tree, a leading innovator in tree insect control, recommends systemic tree injections to control tree insects. Using systemics ensures that only the tree gets the product, not the surrounding environment. Click here for more information about the use of systemics to control tree pests.
