- PREPARE A NEW DAYLILY BED Preparing the soil for a new daylily bed before digging the old clump allows you to get the divisions into the ground without delay, before their roots become dried and damaged from exposure to the open air. Remove any weeds from the chosen spot and work the soil to a depth of a foot or so, incorporating several inches of compost, well-rotted manure, or damp peat moss to make the soil more friable and moisture-retentive. Daylily divisions planted in well-prepared soil will begin to grow quickly and become established before the onset of winter.
- DIG THE CLUMP Cut back the clump's long outer leaves to about six inches to make it easier to handle. Try not to damage the new inner leaves growing in the center of each fan. With a spading fork, loosen the soil all around the clump. Work around the perimeter several times to free as many of the roots from the soil as possible. Because daylilies develop extensive root systems, it may be necessary to dig down 10 to 12 inches. Don't worry if you accidentally break a few of the longer roses—new ones will grow when the divisions are replanted.
Next, use the fork to pry the entire clump out of the ground. Shake or wash excess soil off the roots so you can see the individual fans.
