butterfly bush looks like it's dying
For at least 6 years now I've had a butterfly bush that has done very well. This year we had spring-like weather very early (mid-March) and so most of my perennials are already growing again. The butterfly bush, however, looks like it is really struggling - unless it just didn't really get started yet. The stems seem brittle and break or split off easily. There is some new growth from what was still there over the winter but the leaves seems dry and brittle. I'm hoping that it is just too early yet for new growth? Otherwise, I'm afraid it might be on the way out. I do prune it back pretty hard during every winter. We had a bad ice storm in fall and I know that many of the big branches were either damaged or broke off from the weight. Any thoughts?
