Best time to plant daylilies is in the spring and fall. Daylilies love sun, full sun if possible, but will tolerate part-shade conditions in well drained soil. A general rule is to make sure they get at least 6 hours of direct sun a day. Many darker colored varieties will benefit from partial shade in the hottest part of the day.
Daylilies will grow in a wide range of soils, from sand to heavy clay, and in a wide range of soil pH. Heavy clay or sandy soil will benefit by digging in compost. Also add sand to clay which will help make it more friable and easier to divide. Divide every 3 to 4 years.
Water is essential for good performance. In sufficient quantity, water helps ensure that you get as many blooms and as large blooms as possible. It is most important that daylilies get sufficient water in the spring, when plants are making scapes and buds, and in summer during bloom season. Daylilies can withstand drought conditions, but you will notice decreased numbers of blooms and smaller bloom sizes.
Daylilies are not picky about their fertilizer. Use a complete balanced fertilizer such as 6-12-12 or 10-10-10 applied in the spring and again in the late summer or early fall. Mulching can be beneficial to your daylilies in several ways. It can help by improving your soil through the addition of organic material, by helping to retain moisture, and by helping to discourage weeds. It can also help keep soil cooler in the winter. The darker burgundy varieties are sensitive to sun scald and will fade out in the afternoon sun. They will benefit from planting in an area getting some afternoon shade.
