Water regularly during the active growing season, especially when young and establishing. Allow the soil to dry slightly between waterings.

Reduce watering significantly in cooler months or when the plant is dormant to prevent root rot. Ensure good drainage to avoid waterlogged conditions.

Pruning is typically minimal for Melilotus indicus. Deadheading can prevent unwanted self-seeding if spread is a concern. If the plant becomes leggy or untidy, light pruning after flowering can help maintain shape.

Remove any dead or damaged stems as needed.

Propagate primarily through seeds, sown directly into the ground in early spring or autumn. Scarification of seeds might improve germination rates for some species within the genus.

Direct sowing avoids transplant shock, as Sweetclovers generally dislike root disturbance.

Repotting is rarely necessary for Melilotus indicus, as it is an annual and often grown directly from seed in situ. If grown in pots for specific purposes, repotting is usually done when young, during the active growth phase, into a slightly larger container with fresh, well-draining soil.
