I’m not quite sure what to make of the weather forecast for tonight. The predicted lows are conflicting, ranging from 21 to 24 degrees. I know, that’s not a very big difference. But it is a big difference for some of our cool weather vegetables. 24 degrees or warmer means little to no damage on most things. 21 degrees means more damage.
I would recommend that you be safe rather than sorry and either cover your fall veggies tonight or else pick and preserve most of what is ready to go.
