Water regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings for established plants.

Young seedlings require more frequent attention to maintain even moisture.

Pruning is typically minimal. Deadhead spent flowers to encourage more blooms and prevent self-seeding if desired. Trim back leggy or overgrown stems in late spring or early summer to maintain a more compact shape.

Remove any diseased or damaged foliage promptly.

Propagate *Sisymbrium officinale* primarily through seeds, sown directly outdoors in early spring or autumn. It readily self-seeds.

Cuttings can also be taken from young, non-flowering shoots in spring or early summer and rooted in moist soil or a propagation medium.

Repotting is usually unnecessary for *Sisymbrium officinale* as it is often grown as an annual or biennial and tends to self-seed. If grown in containers and a larger pot is desired, repot in spring before new growth begins, using a well-draining potting mix.
