Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering in winter when the plant's growth slows down.

Ensure good drainage to prevent root rot, especially in pots.

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

Pinch back tips to promote branching.

Gymnanthemum amygdalinum can be propagated from stem cuttings. Take 10-15 cm cuttings from healthy, non-flowering shoots in spring or summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep moist and warm for successful rooting.

Repot young plants annually or every two years, and mature plants every 3-4 years, or when root-bound. Use a well-draining potting mix. Choose a pot only slightly larger than the current one.

Repot in spring before the active growing season begins.
