Do Daylilies Spread

Daylilies quickly spread into larger clumps, and eventually they become so crowded that they do not bloom as well. You may want to divide your daylilies every few years, particularly if you notice fewer blooms.

How quickly do daylilies spread?

Unless you’re growing H. Fulva, Kwanso that can spread quickly to take over the whole bed in just a few years, they can be planted 18 – 24″ apart. I have one clump, undisturbed for at least 5 yrs., perhaps even 8 yrs.

How do you make daylilies spread?

Some gardeners have had good luck mowing down daylilies and then smothering them with thick layers of mulch. Apply 4 to 6 inches (10-15 cm.) over the daylily stand, but be prepared to fight with them through the season. Like any perennial weed, the daylilies will continue to try to send new growth up through the mulch.
