Ash Tree and the Emerald Ash Borer #389073
Asked March 17, 2017, 2:25 PM EDT
I live outside of Morrison (SE) in unincorporated Jefferson County and have a mature Green Ash about 80" around the trunk at 4.5' in height. I was wondering if I should be concerned about the Emerald Ash Borer yet and if I should treat my tree this spring. I understand the Emerald Ash Borer has been contained to the Boulder County area, but I'm wondering if there is a great potential that it could infest my tree too. I've used a concentrated product with Imidacloprid in it over the past couple years and wonder if it's a good option for prevention or if it's even necessary at this time. Thanks.
