splitting lilies in spring
I planted three asiatic lilies about three years ago, now there are about 20 or 25 in a 2 by 2 foot area. They are way to close to look nice or grow well. Can I split them in the spring, or will it stunt their growth/make them bloom later. If I can split them with no repercussions, how do I do it? Any info would be great, thanks.
