Despite their humble beginnings, root cellars tend to be overdesigned. However, your root cellar plans do not have to be extravagant. Let’s not forget they are just holes in the ground, people! 

With a modest budget and some effort, you can install an inexpensive DIY root cellar in your home or backyard. 

Keep reading if you are curious about root cellars. We will explain why root cellars are so effective and share 10 ideas for how to make a root cellar at home. 


What Is a Root Cellar?


A root cellar is a below-ground storage location that relies on the earth’s natural cooling, humidifying, and insulating properties to keep food from spoiling. Specifically, root cellars are designed to take advantage of the cool temperatures below the soil’s frost level. 

Root cellars are used to keep a variety of food fresh for long periods of time without electrical refrigeration. So despite the name, you aren’t limited to keeping roots down there! 

    • Fresh fruits and vegetables
    • Jars of pickled produce 
    • Seeds and rhizomes 
    • Wine and beer
    • Food coated in food wax

Root cellars date back to the 18th century. Root cellars were typically vaulted, lined with stone, and had some sort of entryway with a door and steps. However, over the years, root cellar plans and materials used to execute the design have evolved substantially.

Advantages of Root Cellars

There are many reasons why root cellars are fantastic, the first of which being that they are extremely energy efficient. Once they’re constructed, root cellars do not require electricity or fuel to operate. This means you can keep your utility bills lower. 

Another advantage of root cellars is their ability to preserve the quality of your food. This means you can have delicious spring and summertime crops preserved for use during the winter and winter root crops preserved all the way through the warmer parts of the year.

These qualities of root cellars add to the third advantage of root cellars: food security. With root cellars, you can store more food for longer periods. Therefore, you become more self-reliant, and less reliant on conventional grocery stores for your food. 

With a root cellar, you will no longer be at the mercy of supply-chain interruptions and grocery store food shortages

What Makes A Good Root Cellar?

Not all root cellars are created equally. For example, cool, dark, and damp root cellars are effective at storing food. But a poorly designed root cellar will not adequately keep your food from spoiling. For a root cellar to be effective, it needs to meet five essential requirements:

  1. Cool Temperatures

The first key component for effective root cellars is the temperature. Ideally, a root cellar will keep a temperature of 32 to 40 degrees Fahrenheit, or 0 to 4.5 degrees Celsius. Generally, the cooler the temperature (without freezing), the better, because less ethylene gas will be released from the crops. 

To get the right temperature, location is everything. Typically, a place with minimal sunshine, like a north-facing slope or shaded area behind your home, is the best. 

Root cellars need to be constructed below the front line to prevent freezing. The depth at which your soil freezes will depend on your geographic location. So we recommend doing some research before digging. 


        2. High Humidity

The next essential requirement for root cellars is high humidity. Ideally, a root cellar will have a humidity level of 85-95%. High humidity levels will prevent moisture loss and evaporation, which will prevent withering.

To get the right humidity level, selecting a location with good drainage is important. How well your soil drains will depend on the soil type you have around your home. 

To prevent waterlogging and get adequate drainage, we recommend using dirt or gravel for your DIY root cellar design. Using natural materials for the floor will also naturally humidify the area and help keep the food from spoiling. 


         3. Darkness

As you might suspect, it is dark underground. That is a good thing. Your root cellar should never be exposed to natural sunlight. Sunlight heats things up and encourages rotting. 

Darkness reduces food deterioration and prevents sprouting. 

This doesn’t mean you cannot have lights in your root cellar. If it’s big enough, you will want to add some lighting to see. You can also use headlamps, flashlights, or lanterns. 


        4. Good Ventilation

For effective root cellar plans, proper ventilation helps maintain the right temperature and humidity within the root cellar. 

The movement of cool air prevents the growth of mold mildew. Plus, proper ventilation will help push out the ethylene gas that is being released from your produce, all of which will contribute to the shelf-life and quality of your food. 


         5. Accessible Location

Lastly, as you think about your DIY root cellar, you want to consider its accessibility. The location of your root cellar is important to maintaining the correct temperature and humidity level. But it’s also important to ensure that you can access it easily. 

You don’t want your root cellar to be a chore. Accessibility of your root cellar increases its usefulness and functionality. This is especially true if you live in areas that experience snowfall. To deal with snow, you might consider constructing your root cellar beneath a shed or covered area. 


10 DIY Root Cellar Ideas

Root cellars come in all shapes and sizes, and can be constructed with various materials. Root cellars can be professionally installed; however, if your budget cannot accommodate professional installation, we wanted to give you ten inexpensive DIY root cellar ideas.

Buried Old Freezer or Refrigerator

The next time you go to a garage sale and see an old freezer or refrigerator, buy it! Believe it or not, freezers and refrigerators make for perfect root cellars.

Freezers and refrigerators are robust and perfect for insulating fruits and vegetables. However, the one drawback of using a freezer or refrigerator as a DIY root cellar is their lack of ventilation. 

If you want to try out this idea, we recommend drilling holes in the freezer or refrigerator and installing PVC pipes with access above ground to facilitate ventilation. 


Bucket or Trash Can Cellar

Root cellars can be created with buckets and trash cans. Yes, a bucket or trash can root cellar will be small. But if you bury multiple in your backyard, we promise you will be impressed with how much food you can keep. 

With bucket and trashcan cellars, or cellars made with other plastic vessels, it’s crucial to insulate with straw or hay. You can insulate the vegetables from one another with hay, but we recommend protecting the entire bucket, barrel, or trash can with hay or straw as well. 

It is also essential to drill small holes in the bottom of the plastic cellar to accommodate adequate drainage. 


Seasonal Cellars

Most times, root cellars are buried into the ground around your home. However, if you do not have ample time for a construction project, or just don’t want to dig a hole, you can simply use the cool and dark spaces you already have around your home. 

Seasonal cellars, such as garages, attics, or other outbuildings, provide valuable space for storing fruits and vegetables. These spaces work best if you live in a location with a mild climate throughout the hotter months and cold winters. 


Earthbag Root Cellar

Earthbags are like sandbags that you fill with soil and other organic material. Compared to other materials, earthbags are extremely economical. Plus, you do not have to dig a hole. Once the earthbags are adequately filled, they are placed like bricks to create the structure of the root cellar. 

However, as you might imagine, earthbags are a rather labor-intensive project. Nevertheless, earthbags are extremely good at creating an environment with the correct temperature and humidity level. 


Cinder Block Root Cellar 

If you want to go all-in with your root cellar, we recommend a cinder block root cellar. A cinder block root cellar will require a substantial investment of time and money, but we doubt you will be disappointed with the results. 


Cellar Under the Porch or Deck

7-Day Survival Food Kit


If you are like most preppers, you love taking advantage of all the unique spaces in your home to store emergency survival food and other supplies. So why not take advantage of the space underneath your patio, porch, or deck?

A root cellar under the porch is ideal because of how dark and cool the space remains year-round. You can simply install a hatch door into the floor of your porch that gives you access to the space underneath. Then you can store food in buckets, totes, or barrels so your food can remain fresh and free from rodents or insects. 


Crawlspace Cellar

The crawlspaces around our homes are often underutilized. If anything, we stuff them full of miscellaneous items that we never use and forget. So why use the crawlspace in your home as a root cellar? 

Crawlspaces make good root cellars because they are well insulated. Plus, crawlspaces are almost always dark. 


Basement Food Storage

If you live in a part of the United States where houses are commonly built with basements, then you are in luck, because you got a root cellar installed without even asking for it! 

Basements are the perfect place for long-term food storage. We love basements as root cellars because of how accessible they are. They require no venturing outside in the cold to replenish your food reserves. 


Root Cellar From Recycled Materials

If you want to make a root cellar, you do not have to use state-of-the-art design plans and materials. Instead, you can create a perfectly functional root cellar from recycled materials. 

Old automobile and tractor tires provide the most popular material for this type of root cellar. Tires are fantastic because they are affordable and excellent at insulating your food from animals and moisture. 


In-Ground Root Cellar 

An in-ground root cellar is the most traditional and effective root cellar design. If you have the time and budget, we cannot recommend this type of root cellar enough. Root cellars are perfect for keeping your produce fresh, as well as other supplies, like your 72-hour kit.

Tips For Storing Food in Your DIY Root Cellar

Constructing a root cellar on your property is fantastic. But now you need to know how to use it properly. Having some root cellar plans for what you want to store and how you plan to store is equally as important as the cellar itself. 

Here are some tips to consider when you begin storing food in your DIY root cellar.

  1. After harvesting your produce, shake off excess dirt instead of washing it with water. Most root cellar vegetables will keep longer when they are put away dry and with a bit of dirt rather than clean and wet.

  2. As you handle your fruits and vegetables, do so carefully. Rough treatment of your products can cause bruising, which will encourage decomposition.

  3. Some fruits, such as pears and apples, like to breathe. Therefore, these fruits should be placed in paper before storage to slow down the release of ethylene gas, which can cause the fruits to spoil faster.
  4. As you organize your fruits and vegetables in your root cellar, we recommend spacing them out on the shelves, and rotating the shelves periodically as well.
  5. Stock your root cellar as late in the season as possible. To do so, you may need to refrigerate some of your produce before putting it in the root cellar. After stocking, check in on your fruits and vegetables regularly and remove any that have signs of rot. 

Final Thoughts on How to Build a Root Cellar 

Root cellars are an inexpensive and energy-efficient solution to preserve fresh food for a long time. They are perfect for the garden harvest or the fruits and vegetables you bought from the grocery store. 

But you don’t only have to keep fresh produce in your root cellar. If you have a root cellar and are ready to stock it with the best survival food and food with a 25-year shelf life, visit our website.
