Will asparagus ferns surive the winter in Oklahoma if stored in the garage out of the weather?

I had the asparagus ferns outside last summer and fall. Before the frost I moved them inside the garage. They have mostly turned brown and the "leaves" are falling off. I haven't cut them back to the stem, is that what I should do?
