We simply can’t stress enough how important it is for Denver residents to take action when it comes to identifying, treating and/or replacing their ash trees as soon as possible. Ultimately, if you have an ash tree, emerald ash borer (EAB) prevention plans depend on how much you value your ash tree. If you’d prefer the safest option with the least hassle, replacement is your best bet. For those determined to hang on to their ash trees, ongoing treatment options also exist. 

The one option you shouldn’t consider, however, is treating or replacing your ash tree yourself if you’re not a licensed tree professional. There are many tree professionals that are licensed by the Office of the City Forester who can lend you a hand.

Reputable tree professionals typically provide a variety of services, ranging from tree evaluations, treatment options, structural management, wood mulch/chip resources and waste disposal. But before you hire someone to specifically treat your ash tree, make sure to ask if he or she has a Colorado State Department of Agriculture pesticide applicator’s license.
