We have a oak tree with it's leaves drying up. This started happening mid summer. It still has a couple of branches that are green and the suckers on the lower trunk. How do I know if it is drought, wilt or blight? Can you tell me someone that can come look at this tree for me? We live by Albert Lea MN.
