Daylilies are deciduous perennial flowers that produce blossoms throughout the summer. Daylilies are available in a rainbow of colors, but not true blue or pure white. These flowers reach 8 to 60 inches tall. Daylilies adapt to a variety of soil, water and light conditions. They also resist insect pests and plant diseases. These plants multiply naturally without any special attention. Every four to six years daylilies need dividing to prevent overcrowding.
Lift the entire clump of daylilies out of the soil with a garden fork in the late fall, winter or early spring. Do not use a shovel since it can damage the roots.
Select the most vigorous daylily clumps from the edge of the cluster. Either discard the center or save it to produce more plants for the garden.
Shake the soil off the roots and wash the roots off with a hose.
Work the roots apart to separate the individual fans.
Trim the top third off the leaves with a sharp knife to reduce transplant stress.
Plant the daylily divisions as soon as possible or store them in moist peat moss in a cool, dark area.
