Water Medicago orbicularis moderately during its active growth period, allowing the soil to dry slightly between waterings. Reduce watering significantly during dormancy in cooler months.

Ensure good drainage to prevent waterlogging, which can lead to root rot.

Pruning is generally not required for Medicago orbicularis, as it is an annual or short-lived perennial that typically dies back after seeding. If necessary for tidiness or to remove dead material, light trimming can be done after flowering.

Medicago orbicularis is easily propagated by seeds sown directly outdoors in spring after the last frost. Seed germination is typically straightforward.

Scarification of the seed coat may improve germination rates for some individuals.

As Medicago orbicularis is often grown as an annual or short-lived perennial, repotting is rarely necessary. If grown in containers and plants survive a year, repot in spring into slightly larger pots with fresh, well-draining potting mix.
