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’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.

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.
