Root Cellars: Cold Room Plans

Root cellars are making a comeback!

Having fresh food without electricity has great advantages for those interested in food security. We’ve had so many power outages where we live (the electricity lines going through forest trees) that having food on hand that isn’t dependent on electricity is a major bonus.

Although I’m trying to have a year-round garden for awesome fall and winter vegetables (even with our Canadian winters & snow!), there is a point when the snow becomes too deep and crops have to be harvested and stored in root cellars.

Root Cellars for Winter Food Storage

What is a Root Cellar?

Root cellars have been used for thousands of years and were essential before the times of refrigeration. Root cellars use properties of the earth to keep many crops cool like carrots, potatoes, carrots, beets, turnips, parsnips, cabbages & other crops cool and fresh during the winter months.

A root cellar may be buried under the ground, in a basement corner or even made with garbage bins. Temperature, humidity, ventilation are all important aspects of a proper root cellar to prevent spoilage:

  • Root cellar temperature of 32ºF/0C to  40º F/4.4C and a humidity level of 85 to 95 percent.
  • The cooler temperatures slows the release of ethylene gas and stops the grow of microorganisms that make your produce decompose.
  • Ventilation is needed to
  • The humidity level prevents loss of moisture through evaporation—and the withering looks that go along with it.

  1. Hello there, thanks for the useful information you provide here. I came here because the produce I keep at my cellar is either shooting or rotting. I didn’t know that potatoes and apples should not be kept together. You have some great designs as well. I will try storing things in bins too. I will find some damp soil and keep beets and cabbages there. I’m very new to this farming thing, so I obviously will make a lot of mistakes before learning the right way of preserving things but blogs like these help a lot. Thanks again. I’d like to get in touch with you to ask some questions, if you could help me I’d be grateful.
