Determining the Appropriate Size
The size of your root cellar depends on your storage needs and the amount of produce you plan to preserve. Consider your garden size, family size, and eating habits.
A small root cellar, around 6×8 feet, might suffice for a small family with a modest garden. A larger family or a more extensive garden may require a cellar of 10×12 feet or larger.
Don’t forget to account for shelving, pathways, and adequate ventilation when calculating the overall size.
Design Considerations: Above-Ground, In-Ground, and Earth-Bermed
There are several design options for root cellars, each with its own advantages and disadvantages. The most common types are:
- In-Ground Root Cellars: These are fully buried, offering the most stable temperature and humidity. They are the most traditional but can be more challenging to build.
- Earth-Bermed Root Cellars: These are partially buried, with earth piled against the walls for insulation. They are easier to build than in-ground cellars and still provide good temperature control.
- Above-Ground Root Cellars: These are built above ground but heavily insulated and earth-bermed. They are the easiest to construct but require more insulation to maintain stable temperatures.
Consider your budget, skill level, and site conditions when choosing a design. A well-insulated above-ground cellar can be just as effective as an in-ground cellar with proper planning and construction.
roofing option, using materials like rigid foam or fiberglass insulation.
