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

Reduce watering significantly during winter dormancy.

Prune lightly after flowering to maintain shape and remove dead or damaged branches. Avoid heavy pruning into old wood, as it may not resprout. Deadheading spent flowers can encourage further blooming.

Propagate from seed, which requires scarification (nicking or soaking) and stratification (cold treatment) for best germination. Cuttings can be taken from semi-hardwood in summer, but are generally more difficult to root.

Repot young plants only when root-bound, typically every 2-3 years in spring. Use a well-draining potting mix, such as one containing coarse sand or perlite. Avoid disturbing the root ball excessively.
