Water the Brazilian soapbark tree regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering during winter dormancy.

Prune to maintain shape and remove dead, damaged, or crossing branches. Light pruning can be done after flowering to encourage bushier growth. Avoid heavy pruning, which can stress the tree.

Propagation is typically done from seeds, which may require scarification or stratification to improve germination. Softwood cuttings can also be taken in spring or summer, requiring a humid environment to root successfully.

Repot young Brazilian soapbark trees every 2-3 years, or when they become root-bound. Use a well-draining potting mix. Mature trees generally do not require frequent repotting and can be maintained in their pots.
