subject: How to Plant and Grow Daylilies [print this page] Daylilies can be planted in spring, late summer or early fall in most areas. The deep south can even plant through the winter months. Though there are many varieties which will mature in different sizes, most can be spaced between one and a half to two feet apart.
Dig the hole a few inches deeper than the depth of the clump itself. If any green foliage is still on the plant, keep it above the ground. Mound about a handful of soil on the bottom of the hole. Spread the tubers of the root system so that they drape over the mound.
Fill in the hole with soil. Press the soil firmly as covering and water to eliminate air pockets in the hole. Deeply water the area every 5 to 7 days for the first 4 to 6 weeks. A good layer of mulch will help to keep the roots cool and moist during the growing season. Use a low nitrogen timed release fertilizer.
Pinch of spent blooms to keep the plant from going to seed. Remove any dead stalks or spent blooms. At the end of their blooming cycle after the leaves begin to wither, cut the plant back to the ground.
Every 4 to 6 years, daylily plants should be lifted out of the ground and the clumps divided and replanted. Don't be afraid. Just take a knife and cut through the large fans down through the roots. Basically each tiny tuber of the root system can be planted to grow a new plant.
Daylilies are one of the easiest plants to grow and especially nice for the new gardener.
