For those who may never have noticed it before, next time you are digging in your garden, once you have dug down about 10"-12", feel the soil with your hands. You will notice it feels warm. That is earth's molten core radiating up heat toward the surface, and it protects a lot of plants and trees throughout the Winter. Our beautiful blue planet really is a marvel.

I used to measure my soil temp with a thermometer, I stopped because I was doing manually every morning. I need to get a wireless sensor one day. Anyway.. It was always at 4 inches down and the soil temp wouldn't fluctuate like the air temp but it would definitely stay cooler. This is because the heat from the sun and air doesn't penetrate down much.
Soil temps DID trend up and down with the air temp though BUT in winter would not drop as much as the air temp, Upper 20s was the coldest while Low 80s was the warmest in the summer. And we surely get colder and warmer than that
But
Zoisite has a good point. Dig them down and they'll have a chance. My Grandfather used to bury is Fig tree every winter
