As the weather changes back to normal (?), in the next days few check out the potential damage in the garden. Within a couple of days after the temps rise above 32, we will be able to see if any of the cole crops have survived.
Two choices, let the plants try and regrow or if they are frozen, put them into a compost pile.
Yesterday, I actualy saw the centers of a chard and cabbage plant, still NOT frozen.
