What's up with my phaeums?
I have a couple of phaeums (I think -- they're called Samobor) that are looking stunted this year. I know people say geraniums should be planted in full sun, but these 2 have been in part shade, getting mostly filtered afternoon sun, since I got them, about 3-4 years ago, and they've always grown and bloomed well. Last summer, though, was pretty dry and I noticed by the end of the summer, their leaves were beginning to die back. Same thing happened with a couple of hostas in the same bed -- leaves died back before summer was over. This spring, they're showing some new growth, but it's rather sparse. (And those hostas never came back at all -- it's like they completely disappeared.) Are these supposed to be divided? Or is something else possibly wrong with them?
