Daylily: Plant in well-drained soil with full sun exposure for optimal blooming. Water regularly, especially during dry spells, but avoid waterlogging. Deadhead spent flowers to encourage continuous blooming and remove yellowed foliage to maintain plant health. Divide clumps every few years in early spring or late summer to prevent overcrowding and promote vigorous growth. Fertilize lightly in early spring with a balanced fertilizer to support robust flowering.
