Water: Coast banksia thrives in sandy, coastal soils and tolerates salt spray, preferring consistent watering every 1-2 weeks. As an evergreen, it retains moisture through its foliage and is best grown outdoors, utilizing natural rainfall for efficient water retention.

Fertilize: For coast banksia, apply a balanced, slow-release fertilizer annually in spring for optimal growth and flowering. Avoid over-fertilization to prevent root burn. Younger plants may need biannual feeding. Water coast banksia before and after fertilization to enhance nutrient absorption and protect roots.

Pruning: Prune coast banksia in early to late winter by removing dead, damaged, or crossing branches to maintain health and shape. Light pruning fosters denser foliage and improves airflow, minimizing pests. Use clean tools to prevent disease, enhancing growth and prolonging blooming for better visual appeal.

Propagation: Coast banksia, a resilient Australian native, thrives in coastal settings and is known for its unique flower spikes and serrated leaves. Propagation via semi-hardwood cuttings with rooting hormone in well-draining mediums is recommended, ideally in a humid environment until roots establish for successful transplanting.

Repotting: Coast banksia benefits from repotting every 2-3 years during spring. Use a wide, deep pot to support its root system. Post-repotting, water sparingly and provide bright light to promote healthy recovery and growth.
