Front roared through here this morning, dropping temps from 63 to 38 in less than an hour and the wind is blowing 25-30 mph. It is supposed to get to 19 for a while tonight. We haven't had this kind of cold in four years. I asked in the vegetable forum early this morning and have not one response so I will ask here amongst my smart friends.
I have lettuce, carrots, cabbages, brussel sprouts, broccoli, onions, garlic, Mexican and creeping oregano, and rosemary. Here is what I have done so far. Harvested all broccoli, radishes, carrots that were big enough. Cabbages and brussel sprouts aren't ready yet. Some lettuce went into my fridge rest is still outside. I have piled leaves around my young brassicas then covered with blankets, same with carrots and onions, garlic too. Nothing for my big plants.
Web says many different things, 25 degrees, 9 degrees, protect, don't protect, die, won't die. Sigh.
In a week we will be back to warmer temps and I really don't want to lose them for one or two nights of cold.
I even have my one remaining milkweed trussed up like a Christmas goose in hopes I can keep some leaves viable for Marty's caterpillars. Fortunately I am through lambing, I learned my lesson four years ago but I have two of my does that are close to popping.
How do y'all handle the winter weather for your winter veggies?
