We got four inches of snow at our house last night, and I'm pleased to report that this morning my winter lettuce is not frozen, not dead, and is in fact as happy as a clam. Good eating this winter! And I mean for our family, not for the deer -- notice that I've put inexpensive fencing around the lettuce patch. I've learned the hard way that deer are also big fans of fresh winter lettuce!
