Overwintering Hens and Chicks (Sempervivum) in Containers

Container vs. Ground Hardiness

Hens and chicks are extremely cold-hardy in the ground (Zone 3–4), but in containers, roots are exposed to freezing temperatures from all sides, which can kill them.

Best Winter Strategy

• Bring pots indoors to an unheated garage, shed, or cool basement (35–45°F ideal).
• Apply systemic insecticide (e.g., Jobe's spikes) one week before moving inside to eliminate soil pests.
• Water sparingly—just enough to prevent desiccation.
• Provide bright light if kept in a heated space to prevent etiolation.

Alternative: Heel Into Ground

Bury pots in a protected garden bed and mulch heavily with straw. This mimics in-ground insulation.

Spring Care: Move outdoors after hard frost danger passes. Gradually acclimate to full sun.
