Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogged roots.

Brachylaena huillensis is relatively drought-tolerant once established, so avoid overwatering which can lead to root rot.

Prune to shape the plant, remove dead or damaged branches, and encourage bushier growth. Light pruning can be done anytime, but heavier pruning is best performed in late winter or early spring before new growth begins.

This helps maintain its aesthetic appeal.

Propagate by seeds, which germinate best when sown in spring in a well-draining compost. Semi-hardwood cuttings can also be taken in summer and treated with rooting hormone.

Ensure cuttings are placed in a warm, humid environment to encourage root development.

Repot young plants every 2-3 years in spring, or when they become root-bound. Use a well-draining potting mix.

Mature plants generally do not require frequent repotting and prefer to be slightly pot-bound, which can encourage flowering. Ensure adequate drainage in the pot.
