There is not anything you need to do for your daylilies before winter. Once the flowers have died back, you can cut the stems and foliage to the ground in the fall or in the spring. There is no benefit to leaving the foliage until the spring, so if you want a more tidy look to your garden area, cut back in the fall. The foliage just needs to be removed before new growth emerges in the spring.
