Tree Care by Species
Common Denver area trees and how to make them thrive. When and where to look for symptoms, trimming guidelines and estimates if needed. We developed a series of pages that address the basics of tree care by tree species.
Aspens – While more drought tolerant, aspen trees need water especially in west facing or windy locations.
Ash – Ash trees are allowed to grow too big in Denver. The city forester of Denver lists it as one of three most common hazard trees in Denver. The predicted emergence of the emerald ash borer, which is different from the Colorado ash borer, will kill most ash trees in the city. What you need to know about ash tree trimming.
Pine – Since they grow all year long, pines need water consistently. Too little water equals a tree prone to pine beetles.
Cottonwood and Maple are common to Denver and make up the other two species, besides ash trees, that are common hazard trees in Denver.
