Water Brachyglottis greyi regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering in autumn and winter to prevent waterlogging, as it prefers well-drained conditions and can be susceptible to root rot if kept too wet.

Prune Brachyglottis greyi after flowering to maintain its shape and encourage bushier growth. Remove dead or faded flower stems and trim back any straggly shoots.

Heavy pruning can be done in early spring before new growth begins.

Propagate Brachyglottis greyi from semi-hardwood cuttings taken in summer. Insert cuttings into a well-draining potting mix and keep them in a warm, humid environment with bright, indirect light.

Roots typically form within a few weeks.

Repot Brachyglottis greyi every 2-3 years, or when it becomes root-bound. The best time to repot is in early spring before the start of the growing season.

Use a well-draining potting compost, and choose a pot that is only slightly larger than the current one.
