Water sparingly, allowing the soil to dry out completely between waterings. Protea acuminata is drought-tolerant once established and susceptible to root rot if overwatered.

Reduce watering significantly during winter dormancy. Ensure excellent drainage to prevent waterlogged conditions.

Prune lightly after flowering to maintain shape and remove spent flower heads. Avoid heavy pruning, as proteas generally do not resprout from old wood. Focus on removing dead or damaged branches.

Pruning encourages bushier growth and better flower production.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Use a rooting hormone and well-draining, sandy propagation mix. Maintain high humidity and moderate warmth for successful rooting.

Patience is key, as rooting can be slow.

Repot young plants only when necessary, typically every 2-3 years, into a larger pot with excellent drainage. Use a well-draining, sandy or gravelly mix.

Avoid disturbing the roots excessively, as proteas are sensitive to root disturbance. Repot in spring.
