problem with my redbud
My @4 year old redbud, 11 ft. tall, has been doing beautifully
despite the inordinate amount of rain we have been getting this summer, south of Pittsburgh, PA. However tonight I noticed all of the leaves on only one branch are either totally wilted or dead and curled! The leaves on all of the other branches are healthy. There are some insect holes but not too many. I could not find any insects, either, or any damage to the branch itself. Any ideas?
