Honckenya peploides thrives in well-drained soil and tolerates drought once established, mimicking its coastal environment. Water sparingly, allowing the soil to dry out completely between waterings.

Overwatering can lead to root rot, especially in heavier soils. In very hot, dry periods, a light watering might be beneficial.

Pruning is generally not required for Honckenya peploides, as it maintains a compact, low-growing habit.

If desired, light trimming can be done in early spring before new growth begins to maintain shape or remove any winter damage. Avoid heavy pruning, as it may not recover well.

Propagation is typically done by seed, which benefits from stratification. Sow seeds in autumn in a well-drained compost mix and leave outdoors to experience winter conditions.

Alternatively, vegetative propagation can be achieved by taking cuttings from semi-hardwood in summer, which require well-drained soil and moderate conditions.

Repotting is seldom necessary for Honckenya peploides due to its slow growth and preference for lean conditions.

If grown in a container, repot only when the plant becomes pot-bound, typically every 2-3 years in early spring. Use a gritty, well-draining compost mix suitable for succulents or alpines.
