This time of year, my tuberous sundews are all in full growth and looking good. But I wonder, can they be too crowded? Obviously, most all plants are eventually susceptible to overcrowding, but when is it too much for tuberous 'dews? My pot of D. gigantea has six or seven large stems growing from the same square inch of soil - would it be better to give them each a little room? My other varieties are similarly crowded. I'm guessing it's better to repot during dormancy, and I'm in no hurry, but should I start planning to part them out?
