Ash Tree

Asked January 6, 2015, 5:27 PM EST

I have three ash trees next to each other and they seemed healthy last summer. Today I noticed one tree has the bark coming off and has signs of bug trails. Is there anything I can do to save the trees or is it to late?

Hello,

I am the Agriculture Agent in Pendleton County. It is highly likely that the damage you are seeing to your ash trees is from the EAB - Emerald Ash Borer. The borer is an invasive species that has been present in the state for a few years now and has had a dramatic impact on the health and population of our ash trees.

You can find images of typical ash borer damage at the following link, http://pest.ca.uky.edu/EXT/EAB/eab%20field%20guide.pdf

Unfortunately if you are noticing a decline in overall health, it is most likely too late to save the trees if it is indeed the EAB. There are prevention chemicals on the market for application prior to the arrival of the EAB. You can find a decision making tool here: http://extension.entm.purdue.edu/EAB/pdf/NABB_DecisionGuide.pdf to determine if your tree is able to/worth saving.

Please contact me should you have any further questions.
