Q. Should we have covered our broccoli before the freeze? It is showing freeze damage from that cold weather we experienced three weeks ago.

A. We usually do not cover broccoli or any of the other cole crops to protect them from the cold, but it is true that if they have heads, they are more likely to be injured by cold weather.  A good strategy is to harvest as much of the heads as you can use before the freeze and then cover any of the other plants that still have heads.
