Water Humboldtia brunonis regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in cooler periods to prevent root rot. Ensure good drainage to avoid issues.

Prune Humboldtia brunonis to maintain shape and remove any dead or damaged branches. Light pruning can be done at any time of year. For more significant shaping, prune in early spring before the main growth flush.

This encourages bushier growth.

Propagate Humboldtia brunonis from semi-hardwood cuttings taken in late summer or early autumn. Dip the cuttings in rooting hormone and plant them in a well-draining potting mix.

Maintain high humidity and warmth for successful rooting.

Repot Humboldtia brunonis every 2-3 years or when it becomes root-bound, preferably in spring. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues and to encourage healthy root development.
