Overwintering Hens and Chicks in Containers: A Denver Guide

Can Sempervivum Survive Winter in Pots?

Hens and chicks (Sempervivum) are famously cold-hardy, many tolerating temperatures well below zero. In the ground, snow insulates roots. In containers, however, roots face extreme temperature swings—freezing harder and thawing faster.

Best Practices for Denver Winters

• Leave them outside if the variety is rated for your zone (most are Zone 4–5 hardy).
• Choose a sheltered spot: Against a south-facing wall, under an eave, or in an unheated garage.
• Insulate the pot: Wrap with burlap, bubble wrap, or bury the container in mulch/leaves.
• Water sparingly: Only during prolonged dry spells when soil isn't frozen.
• Ensure drainage: Elevate pots on feet to prevent waterlogging.

Strawberry Pot Considerations

The side pockets dry out faster. If moving indoors isn't practical, cluster pots together and mulch heavily. Come spring, they'll bounce back vigorously.
