Sesbania campylocarpa prefers consistent moisture, especially when young. Water deeply once the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly during cooler periods, but do not allow the soil to dry out completely.

Prune Sesbania campylocarpa to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to maintain form and size.

Avoid heavy pruning, as it can reduce flower production in the subsequent season.

Propagate Sesbania campylocarpa by seeds. Scarify the seeds by nicking them or soaking them in warm water for 24 hours to improve germination rates. Sow seeds directly into well-draining soil after the last frost.

Germination typically occurs within 1-3 weeks.

Repot young Sesbania campylocarpa plants annually in spring if they become root-bound. Use a well-draining potting mix. Mature plants are generally best left undisturbed.

If repotting is necessary, choose a pot only slightly larger than the current one to avoid overwatering.
