I have had a gardenia plant in a pot on my back deck since this past June. It has considerable growth since then and now I want to know how to care for it this winter. Should I plant it, or keep it in a heated garage? If the latter, at what temp?

Depending on its size, you may want to lightly trim it prior to overwintering. I would suggest bringing it indoors. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/flowers/gardenia/gardenia-plant.htm
