Water regularly, especially during establishment and flowering. Allow the soil to dry slightly between waterings once established. Avoid overwatering, as this can lead to root rot.

Reduce watering in late spring as the plant matures and enters dormancy.

Pruning is generally not required. If desired for tidiness or to encourage denser growth, light trimming can be done after flowering.

Allow the plant to set seed, as this is crucial for its life cycle and subsequent regeneration.

Propagation is primarily through seed. The seeds are often sown in autumn. Natural regeneration occurs through self-seeding and the plant's unique ability to bury its fruiting bodies underground.

Repotting is not applicable as Trifolium subterraneum is an annual groundcover plant. It completes its life cycle within a single growing season and is typically sown directly into the ground or pots from seed.
