Water: Wart-leaf ceanothus prefers drier conditions and demonstrates drought tolerance, thriving with watering every 1-2 weeks to allow soil to dry out. Best grown outdoors, it requires well-draining soil to prevent waterlogging and support healthy root development.

Fertilize: For optimal growth, wart-leaf ceanothus requires a balanced nutrient blend in early spring and late summer. Use slow-release fertilizer to prevent overfertilization and water thoroughly after application. Adjust quantities during seasonal changes to protect against root burn, ensuring wart-leaf ceanothus's health and vitality.

Pruning: Wart-leaf ceanothus features unique warty leaves and benefits from late spring pruning after blooming. Use sharp shears for removing damaged branches to enhance structure and air circulation. Light, regular shaping is preferred to promote healthy growth, resilience, and disease prevention.

Propagation: Wart-leaf ceanothus thrives through cutting propagation. Use healthy, semi-hardwood stems, dip in rooting hormone, and plant in well-draining soil. Consistent moisture and warmth are essential for root development, while minimizing stress and avoiding waterlogging are crucial for successful propagation.
