Planting Daylilies
Daylilies should be planted 18-36" inches apart. If you would like an immediate display of color, the daylily plants can be spaced closer together, but keep in mind that they will need to be divided sooner than those spaced further apart.
Daylilies should be planted in a hole that is large enough so that the roots can be placed without having to be twisted or bent in any way. If the daylily has been dug from a clump, it is a good idea to cut the foliage back to about 5 inches to better allow the plant to concentrate on reestablishing it's root system, rather than working to supply the leaves with water and nutrients.
Place the daylily fan into the hole. The roots should be spread out in the hole and the crown should be positioned 1 inch below the ground line. Fill the hole with soil and and cover the crown with 3/4" - 1 1/2" inch of soil. It is important to not plant the daylily too deeply - too shallow is better than too deep!
Tamp the soil firmly around the roots and water thoroughly. If healthy, the plant should begin to grow immediately.
