I noticed this summer that a 2 out of 3 of my elm trees, right next to the wood shed ironically, lost there leaves in July. I was haying the farm this summer and saw some elms down there 3 miles from my house also lost there leaves, Bronz leaves were all over the ground, we had a drought, but I can't see that hurting the trees. I did see a wood pecker on the trees that lost there leaves, and the bark is laying all over the ground,, and the trees look a different color on the bark, could this be Dutch elm disease that caused this to happen? Wood pecker eating the beetle? I dident cut them down yet, I'll see if they leaf out next spring, if they don't I'll cut them down for firewood. I'm not crying over them, my favorite hardwood tree is the sugar maple, and hemlock, and white pine for evergreens. Lol.
