Interesting Facts

Old man banksia is a tree native to Australia. It produces large amounts of nectar, making it an important food source for small mammals who, in turn, pollinate the tree. Although old man banksia is easily killed back by wildfires, the same fires increase germination of its seeds, helping it to make a comeback.

Name Story

Old man banksia: Old man banksia is also known as Banksia serrata. The genus, Banksia, was given in honor of Sir Joseph Banks.

Water: Old man banksia, native to fire-prone Australia, exhibits excellent drought tolerance and requires watering every 2-3 weeks. It thrives in well-draining soil and is susceptible to root rot if overwatered. Best suited for outdoor cultivation, it benefits from rainfall patterns similar to its native habitat.

Fertilize: For optimal health, old man banksia benefits from balanced nutrition fertilizers with equal NPK ratios applied every 6-8 weeks during the growing season. Use controlled-release formulations, adjust feedings with seasons, and water soil beforehand to ensure effective nutrient absorption and prevent root burn.

Pruning: Old man banksia features serrated leaves and vibrant flowers. Prune in early to late winter to eliminate dead branches, promoting growth. Trim young shoots to nodes and avoid heavy pruning to prevent stress. Regular light pruning enhances air circulation and reduces disease risk, maintaining a healthy look.

Propagation: Old man banksia can be propagated from seeds requiring careful pre-treatment to mimic bushfire conditions, like hot water or smoke soak. Ensure well-draining soil and maintain moisture without overwatering. Utilize a greenhouse for optimal temperature and protective growth, ensuring robust seedling development.
