Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as Strophanthus barteri is susceptible to root rot. Reduce watering during the cooler, dormant months.

Ensure good drainage to prevent waterlogged conditions.

Prune to shape the plant and remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to encourage bushier growth. Avoid heavy pruning, as it can stress the plant.

Use clean, sharp pruning tools.

Propagation is best done from seeds sown in well-draining compost in spring. Germination can be slow and erratic. Cuttings are also possible but can be challenging to root.

Ensure a warm and humid environment for seeds or cuttings.

Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot only slightly larger than the current one. Repot in spring, just as new growth begins. Handle the roots gently.
