Answer: If the strawberry jar is porous terra cotta (and most are), the container can split or shatter if exposed to below freezing temperatures or alternating freezing/thawing. To be on the safe side, cut the foliage off your strawberry plants and plant them in the ground with the crowns just at soil level. When the weather gets really cold mulch over the tops of your plants with straw or pine boughs. Remove the mulch material in the spring when the weather warms. After removing the strawberry plants, clean the strawberry jar well and store it in an area that remains above freezing during the winter. In the spring you can refill the jar with fresh potting soil and the strawberry plants.
