I've had some leaf curling, but this is crazy! I think I treated these with the Ortho Bug-B-Gone to get rid of any unseen critters, but I'm not sure. I have 2 Rum Runners that are doing this in my yard. The buds are blackening and dropping off before bloom! The thrips problems I have with Celia and Double Peach never caused any blackening on the buds that would drop, but that's what's happening to my Rum Runners. Any ideas??
