I planted a couple of butterfly bushes last year and they were beautiful. But this spring one looks dead with no leaves and the other looks like it's dead, except it has a few leaves scattered all over. I did not prune them. Should I prune them now, and if so, how much? Is one dead and one not? I live in Kansas, Zone 6. Am I just expecting too much too soon? They are the Black Knight.
