How to prune the Ms. Ruby Butterfly Bush?
I have a proven winners Ms. Ruby Butterfly Bush and I planted it last spring and it has done very well. I was getting ready to prune it and wondered if anyone has experience with the Ms. Ruby?
The Proven Winner's site says this: "Prune in late winter or early spring. In Northern states, this plant will die back to the ground though the roots are hardy."
So the question I have is should I cut it back to the ground or leave some of the main branches in tact?
