Sea Rocket thrives in well-drained soil and tolerates drought once established. Water sparingly, allowing the soil to dry out between waterings, especially in coastal conditions.

Avoid overwatering, which can lead to root rot. Monitor moisture levels, particularly during dry spells, but its resilience is a key trait.

Pruning is typically not necessary for Sea Rocket. Remove any dead or damaged foliage as needed to maintain a tidy appearance. Pinching back the tips of young plants can encourage a bushier habit.

Avoid heavy pruning, as it can disrupt the plant's natural, sprawling growth pattern.

Sea Rocket is easily propagated by seeds. Sow seeds directly outdoors in early spring or autumn, as they require stratification and prefer cool conditions. Germination can be erratic.

Cuttings are less common but can be taken from softwood in late spring or early summer.

Repotting is generally not required for Sea Rocket, as it is often grown as an annual or short-lived perennial.

If growing in a container and it becomes root-bound, repot in spring into a slightly larger container with fresh, well-draining potting mix. Ensure good drainage to prevent waterlogging.
