I have divided my daylilies in the spring, but I also successfully divide them now. I usually wait until after they have finished blooming, then dig up the clump and pry them apart into reasonable pieces, then replant or pot up to give away. I trim the foliage back to about 6 inches. I have many pots sitting out near my laneway of daylilies I divided last week. I had some very large clumps of some of my older varieties that had been in the garden for years, such as Luxury Lace, Raspberry Pixie, Siloam Pee Wee, Cream Drop, etc. I divided Stella a couple of years ago, but she is such a fast grower, that I could do it again!
