DIY Root Cellar Plans & Ideas


Just like most of you, I cannot store all the things I need in my refrigerator. There is just too much to fit in there. Vegetables, fruits, salted meat, jams, potatoes, carrots, beets, turnips, and some drinks are just some of the stuff I need to stay fresh for months. 

As an alternative to my refrigeration needs, I went back to the good old days. This was when root cellars were the real deal when it came to keeping supplies fresh. 

You might think I am old fashioned, but these are still in use up to now. Whether it is in your basement or a distance from the house, root cellars are a cheap way of keeping most products fresh. Moreover, they require no energy to run, unlike our refrigerators. 

Are you interested in putting up one to store your summer produce? Or do you want to upgrade your existing one? Well, I have prepared some DIY Root Cellar Plans and Ideas to help you prolong the lifespan of your perishables. 

What exactly is a root cellar and how does it work?

I am not the type to assume that every one of you knows what a root cellar is. Some of you could be hearing about it for the first time and are wondering what it could be. 

It can simply be defined as a storage location that makes use of the earth’s natural properties to insulate, cool and humidify its environment. It must, therefore, be dug or covered with a layer of earth for proper functionality. 

For more effectiveness, certain conditions have to be maintained inside the root cellar itself. The temperature should be between 320 and 400 F while the humidity levels should be between 85 and 95 percent. 

Under such cool temperatures, the rate of ethylene gas production and release is reduced. This inhibits the growth of the microorganisms responsible for decomposition. 

Under such high humidity levels, evaporation of moisture in the stored product is prevented. Consequently, the withering process that accompanies moisture loss is eliminated. 

If you are to locate this outside the house, then ensure that the door faces north. In this manner, the heat from the sun will not be much of a challenge. 

DIY Root Cellar Ideas

After scouring around the web for hours and talking to my friends with root cellars, I have come up with these ideas and plans to help you started on your own.


  • Concrete Septic Tank Root Cellar


If your storage property happens to be located in a hilly area, and you have access to a concrete septic tank, then this root cellar could match your storage needs. 

All you have to do it is sink the concrete tank into the hillside, install doorway and then the vents. Unused Concrete septic tanks can be bought in different sizes and capacities. 

When done, you will have an adequate storage space that uniquely blends in with your property.

  • An Earthbag Root Cellar


If you need a multi-purpose earthbag for your storage needs, then this plan is worth your while. This highly versatile structure can be used for your studio needs, as a chicken coop, a root cellar or anything that you may want it for. 

And because it is so small, building permits will not be required from you. The structure is rigid too such that you can use it as a storm shelter in case of a tornado or even a hurricane.

Putting it up employs readily available materials, thereby cutting the costs. The end result is also an attractive structure on your property.

  • Survival Root Cellars


A root cellar does not necessarily have to be fancy to meet your needs. All you need is a storage space that can be covered with earth. One of the cellars is built from cinder block or cement and covered on three sides, leaving one side of the door. 

Alternatively, you can use barrels and steel drums for more simplified root cellars. As long as they can keep your stuff consumable for a while, you are good to go.

If you are a big fan of a little complexity at times, then here is an idea for cellar needs. What strikes me most about this plan is the gorgeous finish, the ample space inside and there is even a spiral staircase to your way inside. 

All the factors that ensure longer fresh produce are considered too. That includes humidity and proper ventilation. And for the tidy arrangement of materials inside, storage shelves can be mounted into place.×453.jpg

  • Hobbit Hole Root Cellar


No need for fancy digging, finishes or shelves. Just a hole for your fresh fruits, veggies and potatoes will be needed to make them fresh constantly.

What you need is a shovel for digging, buckets for storage, and the strength to dig. The buckets full of potatoes and veggies are placed in the hole, a wooden door is used to cover the hole, and then the organic matter is used as cover. This provides the necessary insulation.

  • Miniature Earthbag Root Cellar


This cellar is almost similar to the one earlier mentioned but is a little smaller in size. Earthbags are used to build the walls instead of cider wood. To save on cost, you can fill bags with sand and use in place of those that are sold commercially. 

The result is an ecologically friendly cellar that keeps all your stuff cool.

  • Dead freezer Root Cellar


Instead of letting that old freezer lie idle in the garage, why don’t you use it as a cellar in your backyard? It works great and is capable of holding a lot of potatoes, helping them stay fresh for months. 

Building it requires a lot of work though as you will have to make ventilation and also ensure Freon does not leak into the soil.×403.jpg
