American searocket thrives in consistently moist soil, mimicking its coastal habitat. Water thoroughly when the top centimeter of soil feels dry. Avoid waterlogging, as this can lead to root rot.

During hotter, drier periods, increase watering frequency to maintain adequate soil moisture for optimal growth.

Pruning is typically not necessary for Cakile edentula. Its natural growth habit is low and spreading. Remove any dead or damaged foliage as needed to maintain appearance and plant health.

Pinching back the tips occasionally can encourage a bushier habit if desired.

American searocket can be easily propagated from seeds. Sow seeds directly in the desired location after the last frost. They germinate readily in well-draining soil.

Cuttings are less common but can be taken from healthy stems in spring or early summer and rooted in moist sand.

Repotting is rarely needed for American searocket, as it is often grown as an annual or in its natural coastal environment. If growing in a container and it becomes root-bound, repot into a slightly larger container in spring using a well-draining, sandy potting mix.
