Water: Hairy ceanothus thrives in well-drained soils with periodic moisture, adapting to moderate water availability. It requires watering twice a week and benefits from mulching to retain moisture, crucial for its health across various climate zones.

Fertilize: For optimal growth and blooms, hairy ceanothus requires balanced fertilizers in spring and high-nitrogen formulations before summer, applied biannually. Adjust seasonal feeding, using slow-release types to ensure nutrient consistency. Always water hairy ceanothus after fertilization to enhance absorption and minimize root burn risk.

Pruning: Hairy ceanothus is a woody shrub with hairy leaves and vibrant flowers. Prune in early spring to enhance growth and flowering, removing dead branches and thinning overcrowded areas. Avoid heavy or late-season pruning to prevent stress and disruption of the blooming cycle.

Propagation: Hairy ceanothus is propagated mainly through cuttings. Use healthy, semi-hardwood stems and cut 4–6 inches long with several leaves. Dipping in rooting hormone aids root development. Place in well-draining potting mix, maintain humidity, and root in a few weeks before acclimating for transplanting.
