Water: Masterwort thrives in damp woodlands and prefers consistent moisture. It should be watered weekly to support lush growth. Primarily grown outdoors, masterwort benefits from natural rainfall, which complements its watering schedule and enhances its growth cycle.

Fertilize: Masterwort benefits from a balanced fertilizer, applied biannually in early spring and mid-summer. Incorporate compost for added nutrition, adjusting amounts per package guidelines to avoid over-fertilization. Water after fertilization to enhance absorption, ceasing feeding during winter dormancy for optimal growth and flowering.

Pruning: Masterwort is a herbaceous perennial with tall stems, green leaves, and white flower umbels. Prune in early to late spring and cut back old stems in late summer or fall to promote growth and prevent self-seeding, using sharp, sterilized tools for clean cuts.

Propagation: Masterwort is propagated by sowing seeds in well-drained, organic-rich soil. Maintain consistent moisture without waterlogging for seedling success. Transplant carefully to prevent root disturbance and monitor for pests and diseases during early growth to ensure healthy development.

Repotting: Spring is the best time to repot masterwort, every 2-3 years, using a slightly larger pot for root space. After repotting, maintain consistent moisture and avoid direct sunlight to help masterwort thrive and display its unique umbel flowers.
