Re: Aroid breeding problems

It is called "Cross incompatibility".  It doesn't occur in all aroids, but a few
species.  Pollination with mix pollen might help in some case.  Delay
pollination (pollinate toward the end of anthesis time just before the stigma
surface no longer sticky) might worth a try.
