Water: Originating from coastal woodlands, bastard guelder thrives in moderate humidity and prefers a watering schedule of once every 2-3 weeks, allowing soil to dry partially. This species is well-suited for subtropical climates, displaying resilience to fluctuating rainfall patterns.

Fertilize: Bastard guelder benefits from high-nitrogen fertilizer for vegetative growth. Apply a balanced NPK every 8-10 weeks during the growing season, reducing in winter. Always water before and after fertilizing to prevent root burn, enhancing bastard guelder's vigor and resilience.

Pruning: Pruning bastard guelder in early to late winter enhances growth by removing dead or overcrowded branches, promoting air circulation and reducing disease risk. This practice also encourages denser foliage and more flowers, ensuring a balanced shape for aesthetic appeal and overall health.

Propagation: Bastard guelder thrives in diverse environments, and effective propagation via cuttings is recommended. Use healthy branches, apply rooting hormone, and ensure consistent moisture and warmth. Transplant rooted cuttings carefully to minimize root shock.
