Problems with Baptisia
This past weekend I hard pruned both my Baptisia to about 15 inches, as I have read some others have done. I had never done this before, but last year they both spent most of the summer laying down and smothering their neighbors. Now today I noticed that some of the leaves have sooty black spots on them (think mildew on fabric), so I cut those branches back to the ground. So I guess my questions are: Did I do something wrong? What should I do now? I hope I haven't done any permanent damage. I've lost quite a few plants to rabbit damage already this year, an early infestation of leaf miners has caused my columbines to lose their leaves even earlier than usual, and many of my annuals are still looking iffy thanks to a late frost right after Mother's Day. Seems it's going to be one of those years where I wonder why I even bother.
