I'm just finishing up my seed order and am struggling with how much to order of Rudbeckia. I have mainly grown Indian Summer, Prairie Sun, and Cherokee Sunset the last few years. They look fabulous in the field but are iffy when I cut them. Some last a long time in the vase and some poop out at random. So needless to say I'm frustrated. I don't want to sell anything to a customer that might be wilted by the time they get home.
I researched this past season to see what I'm doing wrong but I still feel unclear about what is the best post-harvest care. Can you lend me some hints on what works for you? Or is this just a common occurance for you as well?
