When

Hardiness
Clustered Silver Skin is hardy to roughly USDA zone 10 — winter lows around -1°C. That means it will not survive frost and needs to come inside.

Winter watering

Cut watering right back — clustered silver skin uses far less while growth slows, and cold, wet compost is the usual cause of winter root rot. Stop feeding until spring.

The mistake that kills clustered silver skin in winter

Watering on the same schedule as summer. In winter that keeps the roots sodden while the plant is barely drinking, and clustered silver skin rots from the base.
