All stepping stone/steppers should be raised up off the ground in winter so they will not freeze to the ground surface. Items that have areas that pool water should be wrapped with burlap or any absorbent material (old blanket/towel) and then wrapped with dark plastic, making sure that water does not accumulate and freeze.
NOTE: The finishes are designed to replicate the look of natural aging, but unlike a painted finish, the patinas do not prevent the natural aging process. Any cast stone item with a patina finish will weather naturally in an outdoor environment. Because each patina is hand applied in a multi-step process and the product is photographed in natural settings, actual colors may vary.
