Water consistently to maintain evenly moist soil, especially during establishment and dry periods. Avoid waterlogged conditions, which can lead to root rot. Reduce watering slightly in cooler months when growth slows.

Check the soil moisture regularly before watering to prevent over or under-watering.

Pruning is typically not essential for native wintercress, but you can trim it back after flowering to maintain a tidy appearance and prevent excessive self-seeding if desired.

Dead or damaged stems can be removed at any time. Light trimming encourages bushier growth.

Native wintercress can be easily propagated by seed sown directly outdoors in autumn or early spring. It also readily self-seeds. Division of established clumps in early spring or autumn is another effective method.

Cuttings can also be taken, though less common.

Repotting is generally not necessary for this plant as it is often grown as an annual or short-lived perennial and tends to self-seed. If growing in containers, repot only when the plant becomes root-bound, typically in early spring, using a well-draining potting mix.
