How to Build a Trash Can Root Cellar

Trash can root cellars offer an easy and affordable way to store winter vegetables. This novel method of cold weather food storage has become popular with hobby farmers, gardeners and back-to-the-land survivalists. Though using an underground container like this may seem counterintuitive at first, this durable and effective approach provides adequate protection from cold temperatures while protecting its contents from soil-borne insects that might enter through its openings.

Root vegetables such as carrots, parsnips and beets make ideal candidates for this innovative food-storage solution. A trash can root cellar‘s cool, dark and moderately humid atmosphere is the ideal environment for prolonging their storage without altering their texture or flavor.

Grab an old, clean metal trash can with a tight-fitting lid, dig a hole larger than its diameter, and place the trash can inside, so its lid sits four inches above the soil’s surface. Line the bottom of the hole with stones or gravel for drainage purposes and help prevent rainwater or snow melt from pooling around it during rainy or snowy weather.

Pack a thick layer of straw mulch around the bottom of the can to act as insulation and protect its contents from colder temperatures. Packing tightly reduces air pockets and keeps humidity levels within its vicinity consistent. A plastic cover that fits over top of the garbage can is essential in keeping pests and moisture at bay, and should be supported by stones or bricks as an additional defense against wind and snow.

Regularly inspect the contents of your trash can root cellar to make sure that they are in top shape. Look out for signs of wear such as rust spots, holes or any deterioration which might compromise its integrity or become vulnerable to pests and rodents. Likewise, examine its interior for mold or mildew; if found, adjust internal conditions by adding or subtracting insulation as necessary and using thermometers and hygrometers to monitor temperature and humidity.

Although a trash can root cellar may provide emergency food storage solutions, it should not be seen as an ideal long-term food storage option for families of people. Instead, other means must also be employed – including home refrigerator or freezer storage units, attics or basements for example. Some gardeners choose earthbag root cellars made up of series of earth-filled bags placed like bricks. Though more labor-intensive than conventional underground cellars, earthbag root cellars still provide an ideal climate to store winter vegetables.
