Water: Originating from dry regions, small knobwood is drought-tolerant, needing infrequent watering every 2-3 weeks. It thrives in well-draining soil typical of arid climates and benefits from gravel mulches to improve drainage and prevent root rot, aligning with its preference for drier conditions.

Fertilize: Fertilizing small knobwood biannually with balanced nutrition in spring and fall promotes growth. During growth phases, apply a high-nitrogen variant monthly. Water after application to prevent root burn, and adjust for seasonal growth. Precision in application is essential for optimal flourishing of small knobwood.

Pruning: To promote healthy growth of small knobwood, perform regular pruning in early spring. This shapes the plant, removes damaged branches, and minimizes sap loss. Focus on thinning overcrowded areas for better air circulation and sunlight, enhancing both the structure and vigor of small knobwood.

Propagation: Small knobwood propagates well through stem cuttings. Choose healthy, non-flowering shoots, use rooting hormones, and plant in a well-draining, organic-rich soil. Maintain consistent moisture and warmth for optimal root establishment, enhancing the chances of successful propagation.
