Norway Maple Issue
We have two Norway Maples in our front yard, have noticed that they have a lot of leaves that seem to be dying at the edges and falling off (completely brown) and are curious if this is related to our wet summer or perhaps something else? This doesn't look like a normal 'turning brown in the fall" as some leaves are perfectly healthy and others, scattered about the tree seem to be dying. We drive around our neighborhood and saw other Norway Maples with similar problems. Any ideas as to the cause?

It is very difficult to say what is wrong with your trees without seeing it. It is quite possible that the wet weather this year has led to some anthracnose or some other leaf spot. It is also possible that it could be something more serious like verticillium wilt. I will give you a couple of links to look at and read. If you think it is something more serious you could consider contacting a certified arborist to come and take a look. They would be able to diagnose the problem and offer a solution. https://ask.extension.org/expert/questions/365931 . http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/verticillium-wilt/ .
