Oh shoot. I forgot about that. Yes, I have had ceramic pieces crack, literally fall apart, when I forgot and left them out. And pots with soil are even worse. I empty those and put them upside down in my shed over winter. Hmmmm. So no matter what if I put them in ceramic posts I couldn't leave them out over winter. Drat. I would only have two fairly small ones so I could being them inside for winter if they would tolerate the change in temp and humidity. We are bone dry up here in winter.
But they like dry so that would work okay.
Thanks for the reminder. I would have been pretty bummed to have the pots shatter over winter. They are cheap but still.
