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. | |

Growing Notes
This banksia has a shrubby form, and can be kept smaller and bushier by pruning. Don't prune more than two years of growth or you risk the plant not budding back.
This dwarf form performs better in pots than the full sized form.
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.
