Water Iberis saxatilis regularly during its active growing season, allowing the soil to dry out slightly between waterings. Reduce watering in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which this plant dislikes.

Prune after flowering to maintain a compact shape and encourage a bushier habit. Remove spent flower stalks to prevent seeding and to improve the plant's appearance.

Light pruning can be done anytime to remove dead or damaged stems.

Propagate Iberis saxatilis from seed sown in autumn or early spring, or by taking cuttings in late spring or early summer. Cuttings root easily in well-draining compost and can be transplanted once established.

Repot young plants annually in spring as needed to refresh the soil and provide more space for root growth. Mature plants generally prefer to be slightly pot-bound and require repotting less frequently, perhaps every 2-3 years.
