How to Take Care of a Pearl Lily
The pearl lily, or "mini pearl" as it is more commonly called, is of the genus Hemerocallis. Lilies in the genus Hemerocallis are known as daylilies. The mini pearl is distinguishable by its small but numerous creamy coral blooms. Like all daylilies, the perennial summer-blooming flower is easy to care for and quite hardy, being pest and disease resistant. It can also quickly adapt to almost any type of soil, including hard clay and sandy soils. For these reasons, the pearl lily and all daylilies are a popular choice for gardeners in most growing zones.
Plant your pearl lily in a location that gets at least six hours of sunlight per day. Although these flowers only bloom for one day, the blooms on each clump rotate, ensuring continuous blooms. The constant blooming will not happen, however, if the plant is not exposed to enough sunlight.
Choose a planting location that will provide good drainage. While the lily can thrive in different types of soil, the location should be well-draining, because standing water in the soil can lead to rotting of the lily's tubers.
Add organic mulch to the soil each spring and before you plant the pearl lily. Work it about 2 inches into the soil. Daylilies grow well without fertilizer, but a yearly application of organic mulch will give the plant a good head start on the growing season.
Prepare the lilies for winter. Wait until the foliage completely dies down in the fall. It will turn brown and wither away. Then remove the dead foliage and cover the area with straw to protect against cold winters.
Divide your pearl lilies every three years. This will prevent large clumps of tubers from developing. Wait until they flower, then cut the foliage back to about 4 inches. Protect your hands with gardening gloves, then dig up the tubers and pull them apart with your hands, making sure that each new clump has two or three stems sprouting from it. Then plant the clumps so that the base of the stems are about an inch underground.
