Root Cellars—5 Time-Tested Storage Ideas for Your Garden Bounty

Categories: Food

Root cellars have been around for hundreds of years. They have one purpose—to enable long-term storage for your harvested fruits and vegetables. History tells us that native Australians were the first to preserved large amounts of yams and other produce deep in the cooling and insulation of earth. Underground storage facilities from the Iron Age have been discovered, and the early colonists in North America came prepared with the knowledge of how to preserve their crops. Our ancestors knew the benefit of keeping a root cellar and used these 5 time-tested storage ideas for their garden bounty. 

I have access to our family’s geneology going back to the 1400’s. Many of my ancestors were farmers, and each generation used a form of root cellar to store their bounty during the winter. Before refrigeration, the root cellar was an essential way to keep turnips, carrots, potatoes, carrots, beets, parsnips and other root vegetables fresh through the winter months. My mother grew up in Michigan, and remembers vividly the root cellar in her basement, built by her father right next to the playhouse he built for my mother and her sister. It was her job to get potatoes out of the potato bin, and bring up various cans stored there by her mother who was an avid canner.

Root cellars are making a comeback, and are highly appreciated by homesteaders and natural living advocates who want to reduce expenses by growing and storing their self-grown harvests. I am so fortunate to have a root cellar waiting for me in our new “forever farm,” which we move in to at the end of this month. I’m doing my best to learn how to maximize its usage, and I want to share some of this information with you so you can consider doing the same thing.

1. What Is a Root Cellar?

Technically, a root cellar is any storage location that uses natural cooling, insulating, and humidifying properties of the earth. Today’s root cellars are often found in basements, or are dug down in the ground or horizontally into a hillside. You don’t need an elaborate root cellar to store vegetables, even for months at a time. You can easily extend the fresh life of root crops using whatever storage space you currently have.

3. Root Cellar Basics

There are three basic conditions a root cellar should provide. The closer you come to matching these ideal conditions in your vegetable-storage area, the better your vegetables will keep.

  1. Humidity—High humidity is essential. Most root crops and leafy veggies keep best in humidity of 90-95 percent. There are three ways to assure this humidity: install a dirt floor, adding water when needed such as pans of water or damp burlap over the produce, pack the veggies in damp sawdust, sand, or moss.
  2. Ventilation—Air needs to be circulated through your root cellar. Because warm air rises and cool air falls, put an air intake down low, and the outlet up high.
  3. Temperature—This is the most important thing. You can borrow cold from the ground, or by letting cold night air into the cellar.

4. Root Cellar Design

Root cellar designs run the gamut from rough and rugged to designer worthy. Some ideas that are inexpensive but useful include:

  • Simple shelving created from rough cut boards and cement blocks
  • Stackable trays that circulate air
  • Simple wood boxes with burlap covers to keep out the light.
  • Buckets, bins, or boxes with lightly dampened leaves.
  • Sawdust or sand
