What time of year is best for dividing daylily clumps? We have been having an early spring and my daylilies are already 2 - 3 inches high. I was out today looking at them and some of them are getting really big clumps. Maybe 20 - 25 fans in some of them. Should I divide them now, or wait until the leaves are bigger? We will probably still have more freezing weather and snow this year. It's just so much easier to see the clumps now when they are small instead of waiting until everything is grown. But I don't want to kill everything because it is the wrong time.
