Water regularly, especially during dry periods, but ensure excellent drainage. Avoid waterlogged conditions, as this can lead to root rot. Allow the top few centimeters of soil to dry out between waterings.

Coastal conditions often provide sufficient moisture.

Pruning is generally not required for Gulf Searocket. Its natural habit is low-growing and spreading.

If desired, light trimming can be done after flowering to tidy up the plant or to encourage denser growth, but this is mainly for aesthetic purposes.

Propagation is typically done by seed. Sow seeds directly in their permanent location in autumn or early spring. Stratification is not usually necessary. Seeds germinate readily in disturbed coastal soils.

Repotting is not applicable to Cakile geniculata as it is an annual or short-lived perennial typically grown from seed directly in its native habitat. It is not usually cultivated in containers where repotting would be a consideration.
