Water deeply but infrequently, allowing the soil to dry out considerably between waterings. In its natural habitat, it experiences dry summers. Reduce watering significantly during cooler months to prevent root rot.

Overwatering is the most common cause of failure.

Prune lightly after flowering to maintain shape and remove spent flower heads. Avoid heavy pruning into old wood, as Banksia dryandroides may not readily resprout.

Light tip pruning can encourage bushier growth, but only when the plant is actively growing.

Propagate from seed, which requires scarification and stratification to overcome dormancy. Soak seeds in hot water, then stratify for several weeks in a cool, moist environment.

Alternatively, cuttings can be taken from semi-hardwood in spring or autumn, treated with rooting hormone.

Repot only when absolutely necessary, typically when the plant is pot-bound, usually every 2-3 years. Use a well-draining potting mix, such as a sandy loam or a mix specifically for Australian natives.

Handle the root ball gently to avoid damage to the sensitive root system.
