How to Build a Root Cellar

Root cellars are underground storage facilities designed to take advantage of nature’s cooling, insulating and humidifying capabilities to preserve fresh produce for extended periods without electricity-powered refrigeration. Before modern refrigeration became widespread, people relied upon such underground vaults as sources for fresh carrots, turnips, parsnips and fruit like apples and pears all winter long; sometimes canned or dried foods were stored as well. Nowadays, root cellars have experienced something of a revival as more people attempt to store fresher and more nutritious produce themselves for longer.

There are various kinds of root cellars you can construct in your backyard. One simple option involves burying barrel root cellars into the earth in order to provide a cooler, darker environment for storing vegetables – especially useful in cold climates where soil moisture content makes temperatures naturally cool and humid; it helps prolonging their shelf life as garden produce from local farms.

At most garden centers, you’ll be able to find DIY barrel root cellar plans or kits available for sale. However, you could also construct one yourself using inexpensive or recycled materials. When creating your cellar it is essential that it features an adequate ventilation system in order to allow fresh air in and out, since certain foods emit ethylene gas that shortens their shelf lives and requires regular airing out. Furthermore, humidity must also be managed effectively in your cellar; using dirt floors or packed gravel flooring would provide greater moisture control without increasing mold growth risk.

Size and location will have an enormous influence on how long a root cellar lasts. To maximize longevity, the ideal location should have minimal sunlight exposure, be close to soil frostline levels and boast good drainage systems. Furthermore, easy access is key so that food can be quickly extracted when needed.

An ideal spot for your root cellar would be beneath a shed or on the north side of your house, enabling easy access to food during winter when it’s not snowing or raining. Be wary, however, as rodents and other vermin can pose serious threats to stored goods. Installing barriers may suffice, or more advanced measures such as installing electronic devices that detect pests and activate alarms upon their presence may also help. There are several books and websites offering advice for creating your own root cellar. Build Your Own Underground Root Cellar” by Phyllis Hobson and “The Complete Root Cellar Book” are both great resources to start off with when starting to construct an underground root cellar. Both books have received positive customer reviews. Furthermore, there are online video tutorials and additional helpful information that will show you exactly how to erect one yourself.
