Centennial Tree Programs

Trees are a significant part of Centennial’s urban environment, providing beauty, shade, and ambiance. Click here for more information about the City of Centennial’s tree programs.

Emerald Ash Borer

Unfortunately, the dreaded Emerald Ash Borer (EAB) arrived in Centennial in 2024, 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. Centennial’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.

Appointment Date

About timing: we can’t guarantee a specific time — our arborist is usually out after 10am, and the day’s route isn’t set until that morning. The good news: you don’t need to be home for the visit. If you’d prefer, we can have him call you when he’s on his way.

When hiring a tree service company, homeowners should consider quality, safety, licensing, and reputation.
