Water: Japanese mugwort thrives in moderate moisture, requiring weekly watering without becoming waterlogged. As an herbaceous perennial, it benefits from outdoor growth, natural precipitation, and seasonal moisture changes. Maintaining adequate hydration during its active growing season is vital for lush foliage and robust growth.

Fertilize: Fertilizing japanese mugwort with balanced fertilizer boosts growth during spring to summer, every 4-6 weeks at 1/2 strength for potted plants. Reduce in fall and stop in winter. Always water before fertilizing to prevent burn. Adjust based on japanese mugwort's response for optimal vigor.

Pruning: Japanese mugwort thrives with regular pruning, ideally in early to late spring, to promote growth and prevent legginess. Remove dead stems and thin dense areas for better air circulation. Cutting back by one-third maintains size and encourages new shoots while enhancing its ornamental appeal.

Propagation: Japanese mugwort is a robust perennial from the Artemisia genus, valued for its medicinal and culinary uses. Propagate by sowing fresh seeds in sunny, well-draining soil. Stratify seeds for better germination. Water carefully to maintain moisture without over-watering for strong root development and regeneration.
