Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, as Hovea linearis is susceptible to fungal diseases.

Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Avoid heavy pruning, as it can stimulate excessive new growth that may be susceptible to frost.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Treat cuttings with rooting hormone and place in a well-draining medium.

Alternatively, sow seeds in spring after a period of cold stratification.

Repot young plants annually or as needed, typically in spring. Use a well-draining potting mix. Mature plants can be repotted less frequently. Ensure the new pot has adequate drainage holes to prevent water accumulation.
