Hens and Chicks (Sempervivum) Heat Stress and Leaf Loss

Transplanted hens and chicks (Sempervivum) show yellowing lower leaves that detach easily after a week of 100°F+ temperatures. Plants are in full sun with sentimental value (grandmother's plants).

Understanding the Problem

Sempervivums are cool-climate alpines. While they tolerate brief heat, sustained 100°F+ causes stress, especially with reflected heat from rocks or containers. Lower leaf loss is a survival mechanism—plants shed older leaves to reduce water demand.

Care Adjustments

• Provide afternoon shade: Morning sun only during extreme heat.
• Water correctly: Allow soil to dry between waterings, but don't let it stay bone-dry for extended periods.
• Don't panic: As long as the central rosette and stem remain firm and green, the plant will recover when temperatures drop.
• Avoid overwatering: Heat-stressed succulents are prone to rot if kept wet.

These are tough plants with strong survival instincts. The sentimental value makes careful monitoring worthwhile, but they're likely to bounce back with cooler weather.
