Water: Blue-beard thrives in well-drained soil, reflecting its moderate drought tolerance from subtropical origins. A watering schedule of once every 1-2 weeks is ideal. Grown outdoors, it benefits from rainwater during the growing season, enhancing its blooming potential.

Fertilize: Fertilize blue-beard with a balanced nutrient fertilizer in spring for optimal growth. Use high-nitrogen fertilizer monthly during the growing season, tapering off in late summer. Adjust feeding based on growth stages and soil conditions, and reduce feeding in winter to prep for dormancy.

Pruning: Blue-beard is a deciduous shrub valued for its blue flowers and fragrant leaves. Prune in early spring by cutting last year's growth to 6-12 inches to promote dense foliage and blooms. Removing weak branches boosts air circulation and light penetration, enhancing growth and shape.

Propagation: Blue-beard is a small, aromatic shrub with attractive late summer flowers. For successful propagation, use semi-ripe wood cuttings, a sharp cut, and rooting hormone. Ensure moist, well-draining soil and a stable microclimate for optimal growth of new roots.
