What planters can stay outside in winter?
Choose The Right Containers Metal, concrete and wood containers typically handle freezes well, as do fiberglass and resin pots. Some plastic pots also survive winter fine, but may become brittle over time. Winter sunlight can fade fiberglass and resin pots. Terracotta, plastic, wood, and thin-walled ceramic containers can crack and break when exposed to freeze/thaw cycles. For safety’s sake, bring most glazed ceramics, plastic, composite and terracotta pots into a garage or basement when temperatures consistently dip below freezing.
