I live in PA and for the summer I had two ferns hanging on a protected porch. They did beautifully and are really full and green. I don't have a place indoors to store them for the winter but do have an unheated storage shed. Do you think after pruning they could survive in the PA winter? They are too pretty to just toss and buy new ones in the spring.
