Can you divide daylillies in the fall? Laurie wrote that her daylillies were ready to be divided and now that the weather is cooling down; what a great time it is to be working out in the garden.
Probably the best time to divide daylilies, and many other perennials, is in the spring when the plants are newly emerging. This way you will do less damage to the leaves when dividing them with a spade. However, you can safely divide daylillies most anytime during the growing season up until about 6 weeks before the first frost (~late Sept.). Perennials overwinter better if they have had adequate time to establish a good root system. Sometimes the freezing and thawing of winter will heave them right out of the ground and the plants may not survive.
So, yes, divide your daylillies! Many divisions can be made from one overgrown daylily plant. Keep them watered until frost arrives.
