I have some overgrown lilies and need to thin and transplant them. They've hardly bloomed this year. I've never
fertilized them and they've been there for at least 20 years. I know, I'm not a good plant mom. :-( When should I do the thinning, transplanting and fertilizing? And, notice in the photo that many of them look like someone sat on them. Could this happen on its own, or did someone trample them down?
