Before I went to a winter vegetable lecture at the library, I looked at my empty garden pots as though they were reproaching me. They seemed to say that I could have found some winter pansies or something, anything, to allow them to perform their function. They are empty because I put the plants that were growing in them this summer into the ground in the west garden. But now I see those same pots as potential protectors of vulnerable crops on a freezing night. They can serve a whole other purpose just by turning them upside down…
