We were hotter than ever this summer. I put all mine in shade and they loved it. I gave them no sun all summer.
I am not familiar of your winter conditions but I have a lot of rain that turns to freezing rain to snow. So pots would be a block of ice even if I had them protected under a building over hang because of blowing rain, freezing rain, snow. That brought me to the no soil planting.
I have lots of pine needles so I use those with leftover aquarium gravel, and just a sprinkle of soil on top. I have not lost any in pots when I started growing them in that soiless mixture. It is what they grow in on the mountains (a drop of soil and rocks).
