Water Italian melilot regularly, especially during its establishment phase and dry periods. Allow the soil to dry out slightly between waterings.

Once established, it is quite drought-tolerant, but consistent moisture promotes better growth. Avoid waterlogging the roots, as this can lead to root rot.

Pruning is generally not essential for Italian melilot. If the plant becomes leggy or unruly, you can prune it back in early spring to encourage bushier growth.

Deadheading spent flower stalks can prevent excessive self-seeding and prolong the blooming period. Remove any damaged or diseased stems as needed.

Italian melilot is typically propagated by seeds. Scarify the seeds or soak them in warm water for a few hours before sowing.

Sow seeds directly into the garden in early spring or late fall, or start them indoors a few weeks before the last frost. Germination is usually good under favorable conditions.

Repotting is not typically a concern for Melilotus italicus, as it is usually grown as an annual or biennial in gardens and is not a common container plant.

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