Water: Chinese twinleaf prefers consistently moist soil, reflecting its native East Asian forest habitat. Weekly watering maintains its moisture needs. As an outdoor plant in shaded areas, mulching is beneficial to conserve moisture and replicate its natural leaf-litter environment.

Fertilize: For optimal growth, chinese twinleaf requires monthly fertilization with balanced fertilizers like 10-10-10 during the growing season. High-phosphorus formulas enhance blooms. Follow product guidelines to avoid over-fertilizing, and reduce feeding in winter. A slow-release option helps provide steady nutrients for strong growth and vibrant flowering.

Pruning: Prune chinese twinleaf in early to late spring before new growth. Remove dead stems to enhance health and promote fuller blooms. Light thinning aids air circulation, reducing disease risk. Manage spent flowers and height for robust growth, following horticultural guidelines for optimal results.

Propagation: Chinese twinleaf is propagated through division by gently separating established clumps while preserving roots. Replant divisions in well-draining soil with adequate spacing. Water thoroughly and maintain moist soil to foster root establishment, avoiding waterlogging to prevent rot.
