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

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.
Greenwood Village Tree Programs
Trees are a significant part of Greenwood Village’s urban environment, providing beauty, shade, and ambiance. The Greenwood Village Forestry Department plants and maintains the trees located in city parks, public right-of-ways, and other public spaces.

Emerald Ash Borer
Unfortunately, the dreaded Emerald Ash Borer (EAB) arrived in Greenwood Village in 2023, and the beetle continues to spread throughout the City. Pretty soon, untreated trees will start to show signs of EAB damage and will most likely require removal. Greenwood Village’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.

Tree Compartmentalization
Trees are among Earth’s most successful life forms and have been around 370 million years. Lifeforms that successfully have ways to content with harm, rot, and disease. Trees form specialized tissues that respond to injury or infections by compartmentalization (CODIT), which walls off the contagion from healthy tissue over long periods.

Finding a Charlie Brown Christmas Tree
How many times has your family watched Charlie Brown’s Christmas Special? Most likely, the answer is a lot, which means your Christmas tree selection narrows quickly to “We want a Charlie Brown Christmas tree.” Fortunately, the Malik brothers ran the Bonzi Nursery, specializing in Christmas trees native to Colorado. Native, fresh-cut Christmas trees include Concolor Fir, Douglas Fir, Scotch Pine, White Pine, Lodgepole Pine, and Spruces.
