Water: Adapted to arid climates, blackbrush acacia exhibits remarkable drought tolerance, needing watering every 2-3 weeks. It thrives in well-drained soils, and overwatering can harm it. Primarily grown outdoors, blackbrush acacia is ideal for xeriscaping, benefiting from its resilience and low maintenance requirements.

Fertilize: For blackbrush acacia, use a high-nitrogen fertilizer to enhance growth and resilience. Apply a balanced NPK blend in spring every 2-3 months, reducing summer use to prevent stress. Follow product guidelines and ensure safety with gloves and eyewear. Adjust applications based on blackbrush acacia's maturity and climate.

Pruning: Blackbrush acacia has thorny branches and is hardy, requiring winter pruning to promote growth and shape. Use sterilized tools to remove dead wood and thin crowded areas for better air circulation. Avoid heavy pruning during the growing season to prevent stress and enhance flowering.

Propagation: Blackbrush acacia propagation involves cutting a healthy branch, treating the end with rooting hormone, and planting in well-draining soil. Covering with a plastic bag or misting maintains humidity. With proper care, roots will develop, allowing for transition to a permanent location.
