Issues with ash trees this year (not ash borer)
I have an ash tree that has several major branches without leaves this year. I have also noticed others in my neighborhood having the same issue. I have consulted with a tree service and they said it is not related to the emerald ash borer insects, but they have seen this issue with ash trees all over the Denver metro area. Can you provide some insight on the cause and the likelihood of the tree surviving? I would also appreciate any recommendations on how to save the tree.
I have attached pictures of the tree.
Thank you in advance!
