Water: Cooba thrives in arid environments with impressive drought tolerance, needing watering every 1-2 weeks. As an evergreen, it retains leaves year-round and requires consistent moisture even during dormancy.

Fertilize: Fertilize cooba with balanced nutrition during the growing season and high-nitrogen formulas before flowering. Apply quarterly or as growth demands, reducing during dormancy. Wear gloves for safety, distribute evenly to avoid root burn, and adjust based on cooba's response for optimal growth and blooms.

Pruning: Cooba is an evergreen plant with drooping branches and fragrant blooms. Prune in early to late winter using thinning and selective heading cuts to improve air circulation and promote bushier growth. Regular pruning enhances health, flowering, and disease prevention while using clean, sharp tools is essential.

Propagation: To propagate cooba, use healthy, non-flowering cuttings with multiple leaf sets and apply rooting hormone. Plant in a well-draining sandy substrate, maintaining moisture without overwatering. Provide warmth and indirect light to encourage robust root system development for successful propagation.
