Things You'll Need:
- Water
- Compost or a low-nitrogen fertilizer
- Mulch
-
Step 1
Water your daylilies at least once a week. Water early in the day and low to the ground. Watering from overhead during the hottest part of the day may cause the blooms to wilt. Daylilies can tolerate drought, but they thrive best with a deep watering of an inch of water or more each week. Consider watering more if your daylilies are planted in sandy soil.
-
Step 2
Fertilize your daylilies with a low-nitrogen fertilizer. Fertilizing once a year during the springtime is sufficient. You can fertilize again after the blooming season, if you feel it is necessary. For an organic garden, you can fertilize by adding compost to the soil once or twice a year.

Step 3
Remove spent blooms. This will encourage more blooms and is best done at the end of the day. Cut the stalks close to the ground when all the flowers are finished blooming.
-
Step 4
Apply mulch around your daylilies to keep soil temperature consistent, but avoid piling mulch right around the base of the plants, as this can stress stem tissues and may lead to insect and disease problems.
-
Step 5
Divide clumps of daylilies. If clumps grow too large, the blooming performance of your daylilies will diminish. In the fall after daylilies finish blooming is considered the best time to divide them, as long as they have at least six weeks before the first frost to get established.
