Removing and Replacing Your Ash Tree

One of the four recommended treatment options for a tree infected with emerald ash borer (EAB) is to remove the tree and replace it with another species that can grow well in Colorado. Though the EAB has yet to be found and confirmed in the Denver Metro Area, the removal and replacement option is both cost-effective and convenient for homeowners.

Step one is removal of the ash tree and step two is replacement. While it sounds easy enough, hiring a tree professional will make this process significantly easier. When searching for a tree professional, this list of Certified Smart Ashes approved by the Denver City Forester is a great place to begin your search. There are many tree professionals that are licensed by the Office of the City Forester who can lend a hand.

We connected with the wise folks at Denver Parks & Rec to ask for their recommendations for tree replacements. We asked for suggestions for species that will easily thrive in our local climate when provided adequate care. Drumroll, please…
