The daylily (Hemerocallis) is widely adaptable to various soil conditions, withstands drought well and suffers no serious insects or diseases. It can tolerate various temperatures and can easily withstand heat or harsh winters. The plant is a vigorous grower and spreads rapidly. An abundance of green foliage is rapidly followed by numerous lily-like blossoms that bloom in the height if summer when many plants are no longer flowering. The flowers appear pink, orange, yellow, bronze and even burgundy. A few cultivars have crinkled petals. Once established the daylily requires very little care.
Mix aged manure and peat moss into the planting location. The soil should feel crumbly to the touch with abundant organic material. Daylilies grow in a wide variety of soils but they require well-draining conditions and will not tolerate wet roots for an extended time period. The plants prefer slightly acidic soil.
Dig a hole that is deep enough for the plant's root system. Place the crown of the plant 1 inch below the soils surface. Spread the roots out in the hole. Fill the hole and tamp the soil down to remove any air pockets.
Water the daylily well once planted. It enjoys moist soil conditions so keep moist until fully established. Once established the daylily is fairly drought tolerant.
Apply 2 to 3. inches of mulch around the daylily. The mulch will help keep weeds down, help the soil retain moisture and offer wintertime root protection. Use bark chips, peat moss, sawdust or leaf debris.
Sprinkle 2 tablespoons of a 5-20-20 general purpose fertilizer around the daylily in the early spring. Water the fertilizer into the soil completely.
