I have a plant that I've been trying to get seed from. The plant has set some pods on it, 5 or 6 this year, but the stems dry up and die before the pods can mature. Should I just consider this plant infertile and move on or is there something I can do to help it along? I have a photo but I lost the name, could be anything I know but It grows really well for me and flowers for a long time.
