Banksia are from mediterranean climates of Australia and adapt well to California, particularly along the coast. They appreciate good drainage, but are somewhat adaptable to heavier soil as long as watering is infrequent (once established) and they are in a sunny spot. Once established they will grow and look their best with deep watering every other week to once a month during summer. If they have sharp drainage they will tolerate even more water.

Notas de cultivo

This banksia has a thick bushy form, but can be kept smaller by pruning. Don't prune more than two years of growth or you risk the plant not budding back. Though many banksia are known to burn to the ground in fire, and then regrow. You can also prune them up to force a more treelike form, this is best started early.

Banksia prefer mildly acidic soil, and if your PH is on the high side you can add cottonseed meal or other mild acidifying fertilizer to lower it. They appreciate nitrogen in the form of fish emulsion or blood meal, but never give them any significant phosphorus and avoid potassium.
