How do I protect my collard greens in freezing weather

Question

How do I protect my collard green in freezing weather? Do they need to be covered? If so, with what and how?

Answer 1

Floating row covers can provide adequate protection for heavy frosts. Cold frames work better for protectiing collards against heavy snows and freezing; however, southernmost regions generally do not require much in the way of winter protection other than a bit of mulching.
