Soil Type

Water: Brown kurrajong thrives in arid regions with high drought tolerance, requiring watering every 2-3 weeks to allow soil to dry out. It prefers well-draining soil and benefits from occasional rain, showcasing its adaptation to outdoor dry climates.

Fertilize: Fertilizing brown kurrajong with a balanced NPK fertilizer promotes healthy growth during spring and summer. Monthly applications are recommended, while reducing fertilization in winter. Ensure even distribution around the base and incorporate gently into the soil for optimal nutrient uptake, supporting vigorous growth and lush foliage.

Pruning: Brown kurrajong requires optimal pruning from early to late winter while dormant. Remove dead or diseased wood and thin crowded branches for better air circulation. Use clean, sharp tools to reduce damage and infection risk, promoting healthier growth and enhancing the plant's shape.

Propagation: Brown kurrajong, native to Australia, is best propagated through cuttings for genetic consistency. Use 15cm semi-hardwood cuttings with multiple nodes, apply rooting hormone, and plant in sterile, well-draining medium. Maintain high humidity and stable temperatures for optimal rooting success.
