Water: Common milkwort thrives in moist environments, showing moderate drought tolerance. Regular weekly watering sustains its health, ensuring soil moisture without waterlogging. Typically grown outdoors, common milkwort benefits from consistent rainfall during the growing season for optimal blooming and vigor.

Fertilize: Common milkwort thrives with balanced fertilizers applied bi-monthly during spring and summer for optimal growth and flowering. Reduce feeding in autumn and avoid over-fertilization. Use half-strength solutions to protect roots and pause feeding in winter to coincide with common milkwort's dormancy.

Pruning: Common milkwort showcases vibrant blue to violet flowers with low, bushy growth. Pruning should occur in early to late spring, removing dead stems and shaping the plant to enhance airflow and blooms. Sharp tools are essential to prevent disease, ensuring a vigorous and visually appealing plant.

Propagation: Common milkwort propagates best through cuttings taken from healthy, non-flowering shoots. Cut just below a node, apply rooting hormone, and use well-draining soil. Maintain moisture without waterlogging, and keep in a warm, bright area. Roots indicate readiness for transplantation.
