Cultivate daylilies in full sun to partial shade in moist but well-drained soil. They tolerate a wide range of soil types and pH levels. Water regularly during dry spells, especially in the first growing season. Apply a balanced fertilizer in early spring and again after flowering. Mulch in autumn to protect roots in cold climates. Divide clumps every 3-5 years to maintain vigor.
