Basic Banksia Care
These are a hardy tree or shrub and require little water once established in the garden. Like many native plants they require excellent drainage and do well in full sun.
Prune spent flower heads to maintain shape, regular light pruning will increase flower production, heavy pruning or cutting back into wood with no growth is not advisable.
Some of the dwarf cultivars make excellent potted plants a free draining potting native plant mix is best. Fertilize potted plants with a slow release Australian Native Plant Fertilizer (these are low phosphorous).
- Sunny position.
