Emerald Ash Borer University

As Arborists in Denver, Mountain High Tree staff members attend and participate in many ongoing education programs so that we’re on the cusp of what is going on in the tree service industry.

One of the biggest tree service topics today is the arrival of the Emerald Ash Borer in Boulder, Colorado in 2013. This devastating pest affects all types of Ash trees, and once it has infested a tree, the tree will perish. Ash trees do not have any resistance and must be protected, so the best course of action is prevention. If you have Ash trees in your Denver landscape, contact Mountain High Tree and we can come out and determine if your tree is in danger. We don’t recommend treatments for all trees, as the Ash Borer has not yet been found in Denver, but as the years go by, we will likely see the need to protect many Denver trees with tree trunk injection and soil treatments.
