Water consistently during the growing season, allowing the top 2-3 cm of soil to dry out between waterings. Reduce watering significantly in winter, providing just enough to prevent complete soil desiccation.

Overwatering can lead to root rot, especially in poorly draining soils.

Pruning is typically minimal. Dead or damaged stems can be removed at any time. Light trimming in late spring or early summer can encourage bushier growth and more flowers.

Avoid heavy pruning, as it can disrupt the plant's natural form and flowering cycle.

Propagation is commonly done through seeds, which benefit from scarification or soaking to improve germination rates. Stem cuttings can also be taken from healthy, semi-hardwood stems in late spring or early summer and rooted in a well-draining medium.

Repotting is infrequently needed for Stylosanthes viscosa, as it prefers slightly restricted root conditions.

If the plant becomes root-bound, repot in spring into a slightly larger container using a well-draining potting mix. Ensure good drainage to prevent waterlogging.
