Custard Candy Daylily thrives in full sun with well-draining soil. Water regularly, especially during dry spells, but avoid waterlogging. Deadhead spent blooms to encourage continuous flowering and remove yellowing foliage to maintain plant health. Divide clumps every 3-4 years in early spring or fall to prevent overcrowding and promote vigorous growth. Fertilize in early spring with a balanced, slow-release fertilizer to support blooming.
