Click the video above to watch me build my earth bag root cellar. My root cellar will be 6x6 and 7 to 8 feet deep. It should easily stay 50 degrees year round and possibly cooler but it will never freeze. This will allow me to store potatoes, beets, carrots, corn kernels and so much more that I'm growing on my Homestead. I may even be able to dig an ice box at the bottom to store meat and other items.
