Answer: Either early spring or early fall are the best times to dig and separate daylilies. That's when the weather is cooler and rainfall abundant. You can dig and divide them now, in summer, but they will stop blooming for several weeks and the foilage may wilt when they are replanted. If you do decide to dig and replant now, provide some shade from hot afternoon sunshine for a week or so, just to help the plants recover quickly from the move.
