After the blooms have died and the stems turn brown, daylilies can be cut back. If you want to divide the plant, which should be done every three or four years, do it in the early spring when the shoots appear. Two spades placed back to back are insert in the ground in the center of the donut-like shape of the plant. Pushed in to the soil, they will divide the plant in half. Remove one half and plant it elsewhere. If the plant is large and the center of the donut has not been divided in several years, the plant can be divided in to four sections, and each section replanted. Daylilies are very hardy and prefer lots of direct sun.
