Editors Note: Even though at this time most of us are worried about whether or not our gardens will thrive this year, I do think it is good to plan for the Winter too, and all of our abundance. Wishful thinking! I found this article on the Living the Rustic Life blog about how to make a simple root cellar for your vegetables if you aren’t fortunate enough to have a cool basement. It is a great and simple idea to store your foods for much longer.

Squirrels may ravage my garden, but I do appreciate their ability to store for winter. My ancestors did too–storing their harvest in self-dug root cellars. Here in Massachusetts, our winters are too chilly to keep crops in the soil, covered with straw, as they did in England. So the American colonists watched the squirrels put their acorns in holes and promptly did the same.

Root cellars make use of the consistent temperature and humidity present just a few feet beneath the soil.  Most cold-weather vegetables thrive in these conditions, thus allowing them not only to be stored throughout the winter but remain alive, with all of their nutrients intact.  Why buy plastic-tasting vegetables that have been shipped thousands of miles when you can have your own fresh, living ones just a few feet from your front door?

Root cellaring is essential for eating seasonally.  It is one of the cheapest methods of food storage and is arguably even more effective than a refrigerator.  Root cellars are also adaptable to any terrain or budget.  They can be as large as an underground room, complete with ventilation shafts and shelving, or they can be as simple as a hole dug into the ground with a bin put inside.  The latter is the route that I took for my own project.

Root Cellar Materials

  • Large Bin or Barrel
  • Rocks (preferably flat)
  • Hay or Pine Needles
  • An Old Door
  • Something to Store (like potatoes)

Root Cellar Tools

  • Tape Measure
  • Shovel
  • Pick
  • Wheelbarrow

How to make a simple root cellar

First, choose a location that won’t flood and that you won’t mind trudging to in the middle of the winter. I chose a clearing in the woods just fifty feet from my front door. Remember, if your root cellar isn’t convenient, you’ll never use it.

Next, start digging.  The size of your hole will depend upon the size of the box or barrel you plan on burying.  Dig a hole larger than the box on all sides, and make the depth at least five or six feet from the surface.  You’ll go through a few different layers of soil, but hopefully, you won’t hit any heavy ledge.

Don’t dig too deep or you’ll find yourself with a well rather than a root cellar. And take care not to leave your hole unoccupied or uncovered.  You don’t want anyone getting hurt.


After your hole is clean and square, fill the bottom of it up with about six inches of large rocks or crushed stone.  This will give excess water somewhere to go so that you do not make vegetable soup prematurely.  The stones will also draw cool air up from the soil and further insulate your crop.


At this point, you need to begin preparing the vegetables you intend on storing.  Since your root cellar can be accessed at any time, you can always add to it.  However, some vegetables must be stored differently than others, so this must be a consideration when you are planning what to put in your bin.  Information on how certain vegetables should be stored can be found in many different books.

In my own cellar, I stored my potato crop. Unless you’re storing massive quantities of potatoes, you can keep them in bins without any special treatment. After digging, allow them a day or so of curing outside.  Use up any potatoes that you accidentally nicked or bruised rather than storing them because they’ll rot.  Beware squirrels, along with excess sunlight, which can turn them green and poisonous.  Once the skin of your potatoes has thickened up, you can carefully add them to the bin.


When you’re confident with your hole and veggies, gently place your bin or barrel onto the rocks.  It’s not a bad idea to fill in around the barrel with more crushed stone, but since I didn’t have much on hand, I decided to forgo it.


Now cover your bin with straw or hay. Since I had neither of the two, I used pine boughs, which worked the same and were actually easier to remove when I needed to get in the bin.


Finally, you will need to cover the hole with something solid.  I happened to have an old barn door lying around, but you can use anything from an old car door to a big sheet of plywood.  Just make sure that it covers the hole completely to prevent water seepage and critters from venturing down there.  If you’re really crafty, you could even put a whole door with the frame on top so that you can just open it rather than having to flip the door over. Either way works.

Also, you may want to leave a tiny crack for airflow but cover this loosely with some pine boughs or hay.  And when the cold weather really rolls in, throw a couple of hay bales on top of the door to fully insulate the cellar.  Remember, we are trying to preserve that steady cool that exists naturally beneath the earth.  Any hot or frigid air from above might disrupt the environment, spoiling or freezing your veggies.


Check on your root cellar every once and a while, and remove any spoiled produce.  One bad apple truly does ruin the lot.

Happy storing and winter eating!

That’s definitely ‘simple’, but if you have ANY types of burrowing critters, such as ground squirrels, gophers etc, they’ll certainly find your buried goodies and make short work it! I would line it with expanded steel mesh or gopher wire at the very least. Chicken wire has too large of openings. Good 1/4 inch hardware ‘cloth’ would work as well. Personally for the few extra dollars in materials, it would be a savings in the long run. The other variations I’ve seen included burying a heavy rubbermaid garbage can, this too is not effective as even determined field mice can… Read more »


Excellent points! The author mentioned crushed stone, but good gauge wire is probably better,

we are surrounded by fields and have mice, squirrels, etc. This would not keep them out. Would however make a good cold frame for growing winter veggies.

Can you use this sort of “root cellar” for storing packaged food say in Mylar bags and such? Also can they be used for storing non food items? I have VERY limited space inside and could store quite a bit outside as we have plenty of space outside of our house.

I would store your Mylar bags in plastic buckets with sturdy lids but absolutely! Traditional root cellars are nothing more than big holes dug in the earth. Their underground location is what keeps the temperature constant and you don’t have to have a house on top of them to reap the same benefits. I have thought of building my own root cellar outside that uses the same concepts just on a larger scale with a roof and door.


@prepperjournal:disqus If you go the route of a larger root cellar, you may want to consider using cinder block. This is what my uncle and grandfather did in building my grandmother’s root cellar. You dig out a square hole, say maybe 9′ by 9′ ( 1 square meter roughly ) then set courses of the cinder block. You can use a basic sand and quick set concrete as mortar. Lock in the corners especially well and you ought not have any collapsing issues. Leave a section open for hanging a rough lumber built door. Get some foam for attaching to… Read more »

Thanks Ben,

Yes, I have looked into building an in ground root cellar before. I have one spot on my property that I could make that work really well, but I would have to convince the wife first…


Would love your thoughts, please comment.x
