Water regularly, especially during dry periods, to maintain consistently moist soil. Allow the top inch of soil to dry slightly between waterings. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering frequency in cooler months when growth slows.

Pruning is generally not required for Austrian Rocket, as it is an annual or biennial that typically completes its life cycle within one or two seasons.

If desired for tidiness or to prevent excessive self-seeding, cut back spent flower stalks after flowering. Remove any yellowing or damaged foliage as needed.

Austrian Rocket readily self-seeds. To propagate intentionally, sow seeds directly outdoors in early spring or autumn. Seeds require light for germination, so sow them on the surface of the soil.

Alternatively, start seeds indoors 4-6 weeks before the last frost date.

Repotting is typically not necessary as Austrian Rocket is often grown as an annual or biennial and allowed to self-seed.

If growing in containers and it becomes root-bound, repot into a slightly larger container in spring using well-draining potting mix. Ensure the new pot has adequate drainage holes.
