My root cellar is in 2 parts of the garage. Garage is heated, but I try to shut as much heat off and 2 spots get cool enough for a half-ass root cellar. I use remote thermomotors in those areas.
Got apples, oranges, squash, potatoes and fig trees in the root cellar areas. Some of these are overload that won’t fit into the fridge. They may only be stored in the root cellar for a month or two and then moved into a fridge. Others are more long-term root cellar storage.
Store bought red potato versus home grown potato. Both stored 6 months in the root cellar.
