Thanks, @mamuang. Some sort of disease was definitely an issue for me last year and my best guess was cherry leaf spot, so I may use the Immunox again. I’m sorry to need clarification; when referencing times according to bloom, is that just flower bloom? I’m not sure I had many flowers last year. I did have a few and even had a fruit start then die, but I wondered if you meant leafing out or if bloom strictly means flowers.
I had to look up canker. Don’t think I’ve seen it (yet!) but did come across a neat podcast interview with Dr. Bob Bors, who worked on the romance series bushes. It talks about their history, name, and a bit of pruning advice. I do wonder if I’m just a bit too south/ humid here in northern va. We get cold out here and I’m probably 6b-ish but maybe the humidity fostered the fungal disease last year. Not sure.
Thanks again, everyone.
