Water Iberis bernardiana regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogging and root rot.

Ensure good drainage to avoid soggy conditions, especially for container-grown plants. Overwatering can be detrimental.

Prune Iberis bernardiana after flowering to maintain a compact shape and encourage reblooming. Remove spent flower stems and trim back any leggy or overgrown shoots.

Light pruning can be done at any time to shape the plant. Avoid heavy pruning in late autumn.

Propagate Iberis bernardiana by sowing seeds in spring or by taking semi-hardwood cuttings in summer. Seeds may require stratification. Cuttings should be rooted in a well-draining potting mix.

Both methods offer successful propagation when conditions are favorable.

Repot Iberis bernardiana every 2-3 years, or when it becomes root-bound. Use a well-draining compost mix, ideally with added grit for improved drainage. Repot in spring before new growth begins.

Choose a pot that is only slightly larger than the current one.
