Daylilies, or Hemerocallis, are bright, showy flowers that compliment any garden area. They are self-maintaining and multiply easily and quickly. Spacing is important when planting because of the plants' own multiplication. With little care the daylily will bloom from early summer to the first frost of fall, making it a popular choice in the garden.
Plant the daylily in tilled soil 4 inches deep. Dig a hole 6 inches wider than the root base of the plant, leaving a small mound of dirt in the center of the hole. Spread the roots of the daylily around the mound and cover the roots with remaining soil. The crown, where the foliage meets the root ball, should not be more than 1 inch below the surface of the soil.
Repeat this process, spacing daylilies 18 to 24 inches apart until all plants are installed in the flowerbed. Firm the soil around each plant and water well.
Spread a layer of mulch 2 inches deep. A shredded mulch will allow water to flow through to the soil much easier than a large bark mulch. Arrange mulch under plant foliage and around the base of each plant. Water lightly over the mulch.
Weed the flower garden weekly, pulling weeds from the mulch and around the plant base. The mulch will provide a barrier and reduce weed growth in the area as well as help the soil retain moisture. Fertilize the entire garden area with a perennial flower fertilizer monthly.
