I bury my pots in the raised bed garden here in Illinois, and that
appears to protect them. However, in checking freezing

depths for Illinois, it could go down to 50 inches, so I wonder
now if this is adequate protection. In your case, being at

a higher altitude could mean a lower depth of the ground
freezing. I would check with your local sources as to what

depth your ground freezes before using a buried pot as any protection.
