Garbage can root cellars are an affordable and simple way to store vegetables and fruits for longer-term storage. A trash can root cellar takes advantage of soil’s natural cooling and moistness to create a controlled environment in which foods can be preserved – an ideal project for prepper households and individuals looking to stockpile long-term supplies of food.
If you no longer plan on using a large garbage can, dig a hole just larger than the can and bury it in the earth. Fill any remaining space with dirt, add a waterproof cover over top, and build up straw or other material around its lid so rain doesn’t seep in and ruin its contents.
Deeper pits tend to work better for this type of root cellar, as the cooler underground air can move toward your garbage can and cool it more effectively. If there’s no suitable location, excavate into a hillside; more elaborate doors may need to be constructed depending on earth stability – these may range from flat surfaces with steps leading down into it, all the way up to an enclosed room complete with stairs!
To maximize the life of your produce, keep in mind that different food requires specific levels of humidity and temperatures for storage. Scaly vegetables like carrots and beets require more moisture while potatoes and onions do well in dryer environments. If a root cellar isn’t the appropriate place for these items, try placing them in crates with damp burlap or sand between layers for optimal storage conditions.
Regular inspections of your root cellar are critical to ensure that pests and rodents don’t take up residence and diminish storage life for your produce. Look out for droppings, gnaw marks or any signs of activity from pests or rodents. Perimeter Fencing: Burying wire fencing around the bin helps deter animals from coming too close, protecting its contents while also deterring animals.
Cedar Chips: Scattering cedar chips around your root cellar to deter pests can help deter insects, as their strong scent drives away many of them. Companion Planting: If you grow your own produce nearby your root cellar, planting pest-repellent marigolds or chrysanthemums in your garden can also help control insect populations and keep pests at bay.
If you’re using a metal garbage can as part of your root cellar, be sure to inspect it regularly for signs of corrosion that could compromise its structure and weaken its effectiveness. If any spots of rust appear, protect it with paint or sealant in order to prolong its lifespan and ensure the long term success of its storage capabilities.
