Easily grown in average, medium, well-drained soil in full sun to part shade. Daylilies perform well in a wide range of well-drained soils, but prefer a deep, fertile loam. Deadhead spent flowers daily for neatness and remove scapes when flowers have completed bloom. Tolerant of summer heat and humidity, but appreciate deep watering in dry spells to keep foliage attractive. Daylilies should be divided to maintain vigor when the clumps become overcrowded.
Daylilies can survive many harsh conditions that other plants cannot including: polluted city environments, slopes, poor and dry soils, near pavement that is salted in winter, and under Black Walnut trees (not affected by juglone). (Courtesy of Missouri Botanical Gardens Plant Finder)
