Tree & Shrub Disease Treatment in Westminster & Denver Metro
Protect Your Landscape. Preserve Your Investment.
Trees and shrubs are among the most valuable features of your property — but they’re also vulnerable to Colorado’s unique climate, soil conditions, and invasive pests. From fungal infections to insect infestations, plant diseases can spread quickly and cause lasting damage if left untreated.
At Stonecreek Tree, Turf & Landscape, our arborist-led team provides
diagnosis and treatment programs that safeguard your trees and shrubs. With over 25 years of experience in Colorado’s Front Range, we know how to identify issues early and apply effective solutions that restore health and prevent future outbreaks.
Common Tree & Shrub Issues in Colorado
Emerald Ash Borer (EAB)
A destructive insect that targets ash trees, often leading to total loss if not addressed.
Chlorosis
A nutrient deficiency that turns leaves yellow and weakens overall growth.
Fungal Diseases
Powdery mildew, blight, and root rot are common in our region’s fluctuating weather.
Aphids, Borers, and Mites
Tiny insects that sap nutrients and spread secondary infections.
Environmental Stress
Drought, freeze damage, and poor soil health that make plants more susceptible to disease.
