While Banksia trees are drought-tolerant once established, they benefit from regular watering during the establishment phase. Water deeply but infrequently, allowing the soil to dry out between waterings to encourage deep root growth. Avoid overwatering, as Banksias are susceptible to root rot in waterlogged soil.The root system of the Coast Banksia is fascinating, particularly its taproot.
