Daylilies are fairly carefree perennials. They do best when they have nearly full sun (they will tolerate shade but usually bloom less), regular watering(at least weekly during bloom season) and adequate nutrients in the soil. Soil should contain humus and a source of nutrients - balanced fertilizers for flower production usually work well. Some cultivars are more tolerant of neglect than others. If you grow roses and other sun loving perennials in your garden, you will be able to grow daylilies.
