We have a Forest Pansy redbud that we planted about 5-6 years ago. It has been a beautiful tree. It bloomed this spring. Then when it was time for the leaves to come out one side of the tree is beautiful. The leaves on the other side were at first small and sparse. No they have all turned brown and died.

We have examined the tree for signs of damage or insects and don't see anything to account for what has happened.

Any suggestions as to what is going on? It would be a shame to lose the entire tree.
