The specific functions of your root cellar will depend on your location and climate. If you live in an area with extreme weather, it’s essential to account for these conditions.
In the southern regions, where winters tend to be mild, maintaining the low temperatures needed for long-term food storage can be challenging. However, a well-constructed root cellar can still achieve cooler temperatures than the outside environment, and controlling humidity can help bring temperatures down enough for effective storage. In hot and dry areas, utilize your cellar to store sun-dried produce, nuts, and grains.
Conversely, if you reside in a colder climate and worry about your harvest freezing, it’s crucial to insulate your walls to keep the chill at bay. A simple bare bulb hanging from the ceiling might provide some warmth, but be sure to cover root vegetables to prevent sprouting. Creative rural building practices often involve covered pits filled with composting manure, as the decomposition generates heat that can warm the root cellar. Keep in mind that cold air tends to dry out the atmosphere, so maintaining humidity with tubs of water is important.
