Optimum time to take a cutting?
To my delight, I've just discovered three different OGRs (I think they're OGRs... I'll post their pics to try to identify when I can figure out how to do it) in an obscure corner of our school courtyard. My plan is to take cuttings and try to root them, but I'd like to do it at the most optimum time for success. I believe I read somewhere that canes that have already bloomed are the best bet. The things are about to explode into bloom, so I'm trying to be patient. At what stage are the chances of success the best?
