Sea-purslane thrives in well-drained soil and tolerates drought. Water sparingly, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, especially in cooler conditions.

In arid climates or during prolonged dry spells, provide occasional deep watering.

Pruning sea-purslane is primarily for shaping and controlling its spread. Trim back leggy stems in spring to encourage bushier growth and maintain a compact form. Remove any dead or damaged branches at any time of year.

Light pruning can also be done after flowering to tidy the plant.

Sea-purslane is easily propagated from stem cuttings. Take cuttings of 5-10 cm in length during spring or summer.

Remove the lower leaves and insert the cuttings into well-draining potting mix or directly into the ground. Keep the soil lightly moist until roots develop.

Repot sea-purslane only when it becomes root-bound, which is infrequent as it prefers slightly constricted roots. This is best done in spring before new growth begins.

Choose a pot with excellent drainage and use a free-draining compost mix, such as a cactus or succulent blend.
