I have a large Red Oak tree. This spring we notice that the leaves were deformed, with most leaves rounded off unevenly, missing their characteristic points. This is all the way up the tree. This fall we are noticing that parts of the leaves have turned a dark brown, some falling off. The rest of the leaf is a nice green (too early for autumn leaf dying). Also, a few leaves have tiny light brown spots. These symptoms do not appear on our other Oak trees (Pin Oak and Burr Oak). I can send photos but this posting has not place to attach them. Thanks for your help.
