Marginals over winter

Any tips for care of marginals over winter ? Will they die if the pond freezes over or should I move them into the greenhouse untill spring.

Most marginal pond plants sold are totally hardy, there's one or two that can be a bit tender but then only in a severe winter.
I just cut the dead leaves down, to stop them rotting down in the pond, and let them get on with it.
