The following image shows leaves from a tree with Oak Wilt.
Here is a photo of leaves from a Live Oak tree that has Oak Wilt.
These were leaves that Chris Dolan brought to our quarterly meeting back in March 2007. I dared to take them home and scan them in. So far, our trees are fine. IF YOUR LIVE OAK TREE LEAVES HAVE THESE RED VEINS, GET THEM TREATED ASAP!!!

From what I understand the best time to trim oak trees is in the dead heat of summer. Second best is dead cold of winter (at least what little we have of it) Trimming during other seasons leaves cuts susceptible to the beetle that carries the disease.

What Type of Oak are these leaves from? Never seen them . My Trees have leaves drying up around the edges and turning Brown while the rest of the leaf is still green..
