Plant sort/species/varieties description
Perennials commonly called Day Lilies offer the gardener continuous blooms from May through September by selection of varieties for the succession of bloom. Individual blooms last but one day each, but another opens the following day. Day Lilies will grow in full sun or partial shade and can be grown in most all parts of the country. The soil requirements are such that most any soil, adequately supplied with plant food, will produce good plants and blooms. They have no serious insect disease problems. Surely the home gardener will welcome this beautiful, easy to grow plant.
For continuous blooms select varieties that bloom at different times during the summer. Blooming period of most varieties lasts about one month. Four or five varieties will usually provide continuous blooms. Most varieties are day bloomers and the flowers close about 6 p.m. The Calypso variety is an evening bloomer.
Hemerocallis search deep for their food. Two feet is none too deep to prepare the soil. Incorporate Fertilizer throughout the soil worked up at the rate of 1 pound per 25 square feet of bed. One stem should be a part of each root division planted. Plant at exactly the same depth they were growing. September is the preferred planting time in most of the country.
Leave tops on for winter protection against heaving, Winter mulch in northern sections. Lift, divide, and replant divisions every third year. Feed Fertilizer Complete Plant Food early each spring, working 1 rounded tablespoonful into the soil around each plant. Frequent soil soaking will be beneficial during the summer dry spells -sprinkling should be avoided.
For the best quality flowers, daylilies should be grown in full sun, however they will tolerate light shade. Daylilies take quite a bit of water and food so they shouldn't be planted to close to trees or shrubs which compete for the moisture and nutrients. Daylilies grow best in slightly acidic, well drained soil which has a high organic content. A pH of 6 to 6.5 might be considered ideal. Although daylilies can tolerate drought, they perform best when they receive a deep watering of an inch of water or more each week. More frequent watering may be necessary if they are planted in sandy soils. A spring application of manure, compost, or a good complete fertilizer such as 5-10-10 or 5-10-5 is very beneficial. A low nitrogen fertilizer (3-12-12) should be applied in the late summer or early fall. Remove the seed capsules after the bloom has faded to prevent seed production which weakens the plant and would decrease the number of flowers next year. Daylilies can be divided every three to four years. The best time to transplant or divide plants is in early spring or immediately after they finish flowering. Dig the entire plant up and gently pull the leaf fans apart, with each division having a minimum of 3 fans. (Newly divided plants may not flower the first summer).
Prepare the planting area by digging a hole larger than the root ball, and down down at least a foot to loosen the soil. Mix in compost, well-rotted manure, sand, or peat moss thoroughly, and then form a mound in the center of the hole. Set the plant in place with the roots spread on all sides of the mound, at the depth at which it was originally growing. Never plant daylilies so that the crown (where foliage and roots join) is more than an inch deep. Add the soil around the roots firming it as you go. When the hole is half filled with soil, water it very well to insure good soil to root contact, and then add the remaining soil. Firm the soil again, leaving a slight depression around the plant to act as a reservoir and water thoroughly. A good mulch of wood chips or bark will help to preserve the moisture in the summer, as well as helping to control the weeds.
