I entered the greenhouse today. This would not be worth remarking upon if I did it every day, but I don't. And since the weather took its sudden plunge a couple of weeks ago, there seemed no point. With highs in single digits some days last week, surely everything would be dead.
But it wasn't. That photo at the top shows what I collected today. Some of it, especially the chard, had clearly frozen; it was limp and dark. But I've washed it and thrown it in the freezer; tomorrow I'll throw it into some soup, where its limp texture won't matter.
