There’s a reason squirrels bury their treasures.
The basic idea is to dig deep enough to hit cooler temperatures. Our ancestors have been storing fruits and veggies this way for many years. When SHTF, root cellars will make a huge comeback.
Any root cellar you plan to dig doesn’t need to be some elaborate and expensive structure. You can fashion a root cellar out of a buried cooler if you do it right. A standard 13 gallon trash can with a lid would do the trick too.
The point is to get your container into the ground and covered in some way (with a mound of earth, with straw, a tarp or foliage) that is protected from direct sunlight.
Root cellars require no electricity.
If you have a Basement, you may be able to transform it into a root cellar.
Small scale root cellars inexpensive to build and require very little maintenance.
You need ventilation for a root cellar to work. Too much moisture inside can lead to rot.
Most root cellars are outside. When it comes time to access the food inside, bring a flashlight to make sure animals haven’t decided to set up camp.
You’ll have to keep the path to the root cellar clear during the winter.
If your area is prone to flooding, your root cellar may flood also.
