So it is supposed to get down to 28 degrees here in DC. So far, I have well-established peas, onions, , lettuce, and radishes that have been growing for a couple of weeks. I also have some strawberries and a budding peach tree, as well as perennial herbs. There are also some newly emerging carrots and Brussels sprouts. I'm definitely covering the strawberries. Should I cover anything else, or will everything survive the frost?
