Water: Originating from arid environments, spiny chloracantha thrives on minimal moisture and stores water during infrequent rains. Water weekly for domestic care, ensuring well-draining soil to prevent root rot and enhance resilience. Its drought tolerance makes it suitable for xeric landscapes.

Fertilize: For spiny chloracantha, regular bimonthly fertilization with balanced nutrients promotes growth and resilience. Reduce application in winter and water well afterward to avoid root burn. Increase fertilization slightly during early growth. Novices should wear gloves, and veterans can enhance absorption by timing applications after rain or watering.

Pruning: Spiny chloracantha should be pruned in early to late spring to improve growth and flowering. Key techniques involve removing dead branches and shaping the plant. Make clean 45-degree cuts to prevent disease, aligning pruning with the plant's active growth for optimal recovery and aesthetics.

Propagation: Spiny chloracantha is resilient and adaptable. Propagation via healthy stem cuttings is effective; applying rooting hormone and planting in well-draining soil aids in rooting. Maintain consistent moisture and warmth for root development, and gradually acclimate established young plants to permanent conditions.
