Water Mountain Houseleek sparingly, allowing the soil to dry out completely between waterings. Overwatering is the most common cause of rot. Reduce watering significantly during winter dormancy to prevent root rot.

Pruning is minimal for Sempervivum montanum. Remove any dead or damaged leaves as they appear to maintain a tidy appearance and prevent potential disease. Dead flower stalks can also be trimmed off after blooming.

Propagate Sempervivum montanum easily by offsets (chicks) that form around the mother plant. Gently separate the offsets when they are a good size and pot them in well-draining soil. They root quickly.

Repot Mountain Houseleek every 2-3 years, or when the pot becomes overcrowded with offsets. Use a gritty, well-draining potting mix.

Choose a pot that is only slightly larger than the root ball to avoid excess moisture retention.
