We have a Deborah maple that we planted a few years ago. Last year mid summer all the leaves dried and shriveled up but did not fall off. In September it looked like the tree was growing new buds. I thought it was all due to the extreme heat we had last summer. Now this spring there is no sign if life from the tree. The bark near the bottom of the tree is splitting as well any idea if this tree would be dead. I do have pictures.
