These pots are frost resistant, but may not be frost proof. It is always best to bring pots inside or under cover during winter. If that is not possible, be sure it is draining well and use pot feet to keep it off the ground. Wrapping pots in bubble wrap or other waterproof material is good practice during winter as well.
