Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in autumn and winter. Ensure good drainage to prevent root rot, especially in containers.

Overwatering is a common issue for Alpine Rockcress.

Prune lightly after flowering to maintain a neat shape and encourage bushier growth. Remove any dead or faded flower stalks to improve appearance.

For older plants, a more significant trim in early spring can rejuvenate them. Avoid heavy pruning into old wood.

Propagate by sowing seeds in a cold frame in autumn or spring. Softwood cuttings can be taken in late spring or early summer and rooted in a sandy compost.

Division of established clumps in early spring is also an effective method for propagation.

Repot container-grown plants in early spring before new growth begins. Use a well-draining compost mix, such as a gritty alpine mix.

Choose a pot that is only slightly larger than the previous one, as Alpine Rockcress prefers to be slightly root-bound. Ensure adequate drainage holes.
