Will Boston ferns come back if put outside for winter in an area where freezes occur?

Boston ferns will not usually handle freeze damage well. However, you can put them into dormancy by placing them in a sheltered area ( a cool, dark place) like an attached garage, a closet or a basement. Water only once a month, but water it thoroughly when you do. It will look dead, but in the spring, take it back out and it should regrow fine.
