Asparagus patch

Well here in Central Indiana we've had some freezing nights and noticed yesterday that a lot of my asparagus have been damage by it. So my question is would it be wise to just mow off what is up so I know what is the fresh ones, since we are early in the season i was thinking I would be okay in doing so! Hope all is doing well in this troubling times.

I think that mowing would be fabulous! I typically break the damaged ones off with my feet or hands.
