Hello, I am new to this posting, and site. I have planted 6 FPRs in the front yard, about 6 years ago, this spring they all were about 10 ft tall and healthy. I had my nephew visit this April 2017, and stripped the lower limbs of all the redbuds as they were just coming out. It now looks like it is dying, but limbs still seem alive. What is the damage? Death or perhaps next year revival?
