Arctic Searocket prefers consistently moist soil, especially during its active growth phase. Water thoroughly when the top centimeter of soil feels dry.

Reduce watering during dormancy, allowing the soil to dry out more between waterings. Avoid waterlogging, as this can lead to root rot.

Pruning is typically minimal for Arctic Searocket. Remove any dead, damaged, or diseased foliage as needed to maintain plant health and appearance.

Pinching back leggy stems in early spring can encourage a bushier growth habit, but is not essential for flowering.

Propagation is best done by sowing seeds directly outdoors in early spring or late autumn. Seeds can also be started indoors a few weeks before the last frost.

Germination can be erratic and may benefit from a period of cold stratification. It is not typically propagated by cuttings.

Repotting is rarely necessary for Arctic Searocket, as it is often grown as an annual or a short-lived perennial.

If grown in a container and it becomes root-bound, repot in spring into a slightly larger container with fresh, well-draining soil. Ensure the new pot has adequate drainage holes.
