Water thoroughly when the top 5-10 cm of soil is dry, typically during warmer months. Reduce watering significantly in cooler periods to prevent root rot.

Ensure excellent drainage, as Banksias are sensitive to consistently wet conditions. Overwatering is a common cause of failure.

Prune lightly after flowering to shape the plant and remove spent flower heads. Avoid heavy pruning into old wood, as Banksia menziesii may not regrow from these areas.

Tip pruning young plants can encourage bushier growth and a more compact form.

Best propagated from seed, which often requires scarification or soaking to aid germination. Sow seeds in a well-draining native potting mix.

Alternatively, strike cuttings from semi-hardwood in late summer or autumn, using a rooting hormone.

Repot only when necessary, typically when the plant becomes root-bound. Use a well-draining native potting mix with minimal phosphorus.

Handle the root ball gently to avoid disturbance, as Banksias dislike root disturbance and can be slow to establish after repotting.
