The emerald ash borer is spreading across the Front Range. Here’s how to protect your trees

A tiny, green insect that bores under the bark of ash trees is spreading in Colorado.  The emerald ash borer has been making its way around the Front Range for the last decade. It damages ash trees and often kills them. And this year it’s been spotted in Denver.  Ash trees make up about one in every six trees in the urban forests along the Front Range. So what can we do to protect ash trees and even fight back against this pest? Karim Gharbi is a horticulture specialist with the Colorado State University Extension who’s been on our show before. Karim joined Erin O’Toole to talk about the emerald ash borer and give a more specific idea of what this so-called “green menace” looks like. CSU Extension offers guidance on fall and winter watering to keep ash trees strong. If you’re looking for an arborist, Trees are Good offers suggestions.  For more info on Front Range pests, listen to In The NoCo conversations about Japanese beetles and miller moths.  Sign up for the In The NoCo newsletter: Visit KUNC.orgQuestions?
