A couple of times I bought plants on those last sales in November. I completely covered them with a pile of leaves, and they survive till spring. Even better, since I have a cold compost pile made of leaves and kitchen scraps, I just put them there and cover by leaves. The plants survive without any issues.
I might need to do the same with my potted chrysanthemums this year. I don't think I will have enough space in the enclosed porch for all of them. I am thinking of making a shelter in a narrow space between the fence and the house, perhaps with Styrofoam and leaves.
