Water Petrosedum rupestre thoroughly when the soil is completely dry, typically once every 2-4 weeks during the growing season.

Reduce watering significantly in winter, allowing the soil to dry out between infrequent waterings to prevent root rot. Ensure good drainage to avoid waterlogged conditions.

Prune to maintain shape and remove any dead or damaged foliage. Pinch back young stems to encourage bushier growth.

Pruning can be done at any time, but is best performed in spring or early summer to stimulate new growth and flowering. Remove spent flower stalks after blooming.

Easily propagated from stem cuttings or leaf cuttings. Take cuttings in spring or summer, allow them to callus for a few days, and then plant them in well-draining soil. Roots will form within a few weeks.

Leaf cuttings can also be placed on the soil surface to root.

Repot Petrosedum rupestre every 2-3 years, or when the plant becomes root-bound. This is best done in spring before new growth begins. Use a well-draining succulent or cactus potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
