Dividing and Transplanting Stella d'Oro Daylilies: Timing and Technique

Stella d'Oro daylilies are beloved for their repeat blooms and compact habit. Over time, clumps become crowded, reducing flowering. Dividing them every few years rejuvenates the plants and gives you more plants for free.

Best Time to Divide

Late summer to early fall (after flowering slows) is ideal. The soil is still warm, encouraging root growth before winter. In cooler zones, early spring also works.

Step-by-Step Division

1. Dig up the entire clump with a garden fork, loosening soil around the perimeter.
2. Gently shake off excess soil to reveal the individual fans (each fan is a separate plant).
3. Pull fans apart with your hands—don't rip. They separate easily with gentle tugging.
4. Trim foliage back to about 6 inches to reduce water loss.

Replanting

Dig a wide hole, make a mound in the center, spread roots over it, and set the crown (where leaves meet roots) about 1 inch below soil surface. Backfill, firm gently, and water well. Space divisions 12–18 inches apart.

Aftercare

Water weekly if rain is lacking. Mulch to conserve moisture. New divisions may not bloom heavily the first year but will settle in and flower prolifically thereafter.
