Sunday Gloves Daylily thrives in full sun to partial shade, preferring well-drained soil enriched with organic matter. Water regularly during the growing season, allowing the soil to dry slightly between waterings. Deadhead spent blooms to encourage continuous flowering and maintain plant tidiness. Divide clumps every 3-5 years in early spring or fall to promote vigorous growth and prevent overcrowding. Fertilize in early spring with a balanced, slow-release fertilizer to support robust blooms.
