Soil Type

Water: Silver banksia demonstrates drought tolerance, thriving with watering every 2-3 weeks. Preferring sandy soils, it flourishes in coastal areas and temperate climates, benefiting from natural rainfall and drainage to support growth cycles.

Fertilize: To promote silver banksia's growth and enhance its foliage and flowers, apply a balanced fertilizer every eight weeks starting in early spring, adjusting for growth stages and seasons. Use controlled-release types to avoid nutrient leaching, and fertilize mature silver banksia less frequently to maintain vigor.

Pruning: Silver banksia features silver foliage and needs pruning in early to late winter. Focus on removing dead branches and maintain its form with light cuts to avoid stress. Pruning during dormancy supports flowering and enhances vigor, making it a resilient garden choice.

Propagation: Silver banksia can be propagated through semi-hardwood cuttings taken in late summer. Use rooting hormone on the cut end and plant in a well-draining mix while maintaining moisture and warmth to encourage root growth, ensuring uniform traits in new plants.

Repotting: Repot silver banksia in spring for optimal root recovery. Every 2-3 years, use a slightly larger pot for space without overcrowding. Ensure well-draining soil and regular watering post-repotting to support growth. Silver banksia is resilient, presenting no unique care challenges.
