I still don't know the best time to move daylilies. I did experiment this year and moved some in Jan., Feb., and March. I don't recall having moved any daylilies that early in the season before. They are all doing fine, even with the late freeze we had in March after I moved them. My least favorite time is during the peak heat of summer, it is very hard on the plants and harder on me. My favorite time is early fall, and if we have many more winters like this year(extremely mild) maybe here in the deep south winter will become a good time to move daylilies. I think fall is best for me because it is after the blooming season and it gives the plants more time to grow and get established before the next blooming season. It seems to me that when I move plants even in early spring it sets back their blooming dates a bit.
