Water Blumea balsamifera thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain away to prevent root rot.

Reduce watering frequency during cooler months, ensuring the soil doesn't remain waterlogged. Overwatering is a common issue, so err on the side of slightly dry rather than consistently wet.

Prune Blumea balsamifera to maintain desired shape and size, and to encourage bushier growth. Pinch back the tips of young stems to promote branching. Remove any dead, damaged, or crossing branches at any time of year.

Heavy pruning is best done in late winter or early spring before new growth begins.

Propagate Blumea balsamifera from stem cuttings taken in spring or early summer. Select healthy, non-flowering stems, cut them to about 10-15 cm, remove lower leaves, and dip the cut end in rooting hormone.

Plant in a well-draining potting mix and keep moist and warm.

Repot Ngai Camphor every 2-3 years, or when it becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix, such as a blend of potting soil, perlite, and sand.

Repot in spring before the start of the active growing season.
