Do I have oak wilt?
Oak wilt effects all species of oak trees but does not cross into other non-oak species.  Though other trees have diseases with similar wilt names.  Oak wilt like all wilting diseases are fungal diseases that affect the living tissue of the plant.  Though it may seem like a simple thing to diagnose this disease has different characteristics on each kind of tree.  In most cases though the end result is very similar.  This fast spreading disease causes quick leaf drop.  Often an entire tree is observed to loose most of its leaves in the matter of days. 

Some pictures are added below to show you some of the different symptoms of oak wilt in different species of oak trees.  You will notice some leaves turn brown completely and others the veins of the leaves turn a red color.  The far right picture is most often the case in trees in the state of Texas.
