Water the savanna canavalia 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 in cooler months or when the plant is dormant. Good drainage is crucial to prevent root rot.

Pruning is generally minimal for savanna canavalia. Remove any dead, damaged, or crossing branches to maintain plant health and shape. Light pruning can encourage bushier growth.

If the plant becomes too sprawling, prune back longer stems to encourage lateral branching and a more compact form.

Savanna canavalia is easily propagated from seeds. Scarify the seeds by nicking them with a file or soaking them in warm water for 24 hours to improve germination rates.

Sow seeds directly into well-draining soil after the last frost, or start them indoors a few weeks prior. Avoid disturbing the roots when transplanting.

Repotting is not typically required for savanna canavalia, as it is often grown as an annual or in its native habitat.

If grown in a container and it becomes root-bound, repot in the spring into a slightly larger pot with fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.
