To plant daylilies dig holes larger than the root masses with a trowel or small shovel. Next, fill in the hole with loose soil, making sure the crown of the daylily is at ground level. Daylilies should be planted at the same depth they were originally grown. Water newly planted daylilies and keep the soil moist until plants are well established. Figure 1 .
Daylilies can survive temporary dry conditions very well, due to their extensive root systems.
However, the plants' bloom size, number of blooms, plant growth and overall vigor can be adversely affected by prolonged drought. Fertilizer should be evenly applied between plants, kept off the foliage and watered into the soil after application. However, daylilies occasionally may be attacked by aphids, thrips, spider mites or grasshoppers, which will damage the foliage and flower buds. Aphids or plant lice are small, soft-bodied insects with sucking mouthparts. They damage leaves, causing the tips of the damaged leaves to curl and die.
