Overwintering Swiss chard
Here in northern Virginia, it's snowed only once this season, and my row of Swiss chard is still alive. I've had thoughts of plowing it under, but the leaves are still usable, and I don't want to kill it just yet.
Has anyone had experience growing chard over the winter? What will happen if it survives and I leave it there through the spring? Will the plants thrive again in summer, or will they be shadows of their former (gigantic) selves?
