Pruning houseleek
Advice for October in the Netherlands
Houseleeks consist of living rosettes that need no pruning. A Sempervivum rosette dies after flowering; remove only that spent, dead rosette and retain the young rosettes around it. Months are guidelines for the Netherlands and Belgium; also assess growth, flowering and the weather forecast.

No scheduled pruning is needed. Retain healthy foliage and living rosettes; selectively tidy only clearly dead or rotting material. Any post-flowering trim depends on the actual flowering stage.
Pay attention to this
- Do not cut through the centre of healthy living rosettes.
- Do not pull out a firmly attached dead rosette if young rosettes lift with it.
- This advice does not cover similar-looking Echeveria or Aeonium.
- Prevent persistent wetness between rosettes; pruning does not repair root rot.
Frequently asked questions
- Why does one houseleek rosette die after flowering?
- That is part of Sempervivum's life cycle. Young surrounding rosettes can take its place.
- Should I cut the flower off early to save the rosette?
- Do not rely on that as a rescue method. The flowering rosette is reaching the end of its life cycle; preserve young rosettes.
- When should the whole clump be pruned?
- Never as routine pruning. Remove only dead material and retain living rosettes.
