Which Vegetables Last Longest in a Buried Storage?

Choosing the Right Vegetables

When selecting vegetables for buried storage, it’s essential to choose varieties that are high in starch and low in moisture. Sweet potatoes, for example, can last up to six months in a buried storage, while carrots and turnips can last for three to four months. Other options include beets, parsnips, and rutabaga. These vegetables are ideal for buried storage because they have a naturally low water content, which slows down the decay process.

Preparing the Storage Site

To create an optimal buried storage site, choose a location with consistent temperatures between 32°F and 40°F (0°C and 4°C). The ideal soil temperature for buried storage is between 40°F and 50°F (4°C and 10°C). Dig a pit or trench that is 6-8 inches deep and 12-18 inches wide. Line the bottom of the pit with a 2-inch layer of straw or sawdust to improve drainage and prevent moisture from accumulating.

Storing the Vegetables

To store the vegetables, place them in a single layer, leaving about 1 inch of space between each item. Cover the vegetables with a layer of straw or sawdust, and then add a 2-inch layer of soil on top. The key to successful buried storage is to maintain consistent temperatures and moisture levels. Avoid disturbing the stored vegetables, as this can cause damage and shorten their storage life.
