Water: Chinese chastetree prefers consistent moisture and can tolerate moderate drought. Watering should occur twice a week, avoiding both over-saturation and prolonged dryness. It thrives outdoors, benefiting from natural rainfall during its active growing season when water needs increase.

Fertilize: Chinese chastetree thrives with a balanced N-P-K fertilizer and high-nitrogen feeds during growth. Fertilize in early spring and late summer, adjusting amounts based on size. Avoid over-fertilization and withhold during dormancy. Water well after applying nutrients, or consider slow-release options for ongoing support.

Pruning: Chinese chastetree features aromatic leaves and blue flowers, thriving with early spring pruning. Essential techniques include removing dead wood, thinning branches, and shaping the canopy to boost air circulation and flowering. Regular pruning fosters bushier growth, while heavy pruning outside this period can stress the plant.

Propagation: Chinese chastetree can be propagated using healthy semi-hardwood cuttings. Cut below a node, remove lower leaves, and optionally use rooting hormone. Plant in well-draining soil, ensuring moisture and warmth. Softwood cuttings can also succeed, but semi-hardwood is preferred for robust root growth.
