I have a patch of false indigo in my front garden. It has been established for several years now. There are probably at least a dozen stalks and it is about 3-4 feet tall. It is currently getting too thick where it is and is starting to choke out our rhododendron bush. (plus the garden symmetry is lop-sided) I would like to divide it up into two patches. I read that false indigo doesn't do well with transplanting, though. Should I try transplanting some and take my chances? Should I just keep the seed pods and plant the seeds in another area of the garden? Is there a better time of year to transplant or thin? (I don't want to completely kill the patch we do have. Thanks for your help and advice.
