I have a red maple (omaha nebraska) that is 2 1/2 about 15 feet tall, beautiful. Currently its top leaves are turning sickly yellow, and they are falling off. What is the problem. I think I may have watered too much. It sits in clay soil, and we have gotten alot of rain, in addition to my extra watering. (Im dumb). What can I do to revive this tree, or is it something else.
