Ok. I have an unheated garage. The reason I was a bit scared of that is that I'm on the warm side of zone 6 (you are so correct about that) and have some pretty wild temperature fluctuations in the winter....with some weeks of warm. Lake Erie is 80 miles away and acts like a heat sink.
Would wrapping the pot in a moving blanket be a reasonable idea? The variety is from H.W.Hyde.....the green double variety that really does not flower out, but stays green and looks sort of like a wheat stalk. It seems a bit temperamental.
What do you think?
