So on a separate thread, I am told that overwintering container plants are not the same as overwintering plants in the ground. I assume this is because the ground act as a thermal sink so that it smooths out the temperature change. Previously I overwintered sedium in pots without any issues, but sedium are really hardy and probably didn't care about the cold.
So what should I do in the winter with container plants. Should I stick them in my unheated garage? I assume even though it's unheated, it's still warmer than the outside.
