Is DIY Construction Of A Root Cellar Feasible For Beginners?

Root Cellar Design Basics

A well-designed root cellar should maintain a consistent temperature between 32°F (0°C) and 40°F (4°C) and a relative humidity of 80-90%. This can be achieved by burying the cellar underground, which provides natural insulation and temperature regulation. A typical root cellar design includes a rectangular pit with a depth of 4-6 feet (1.2-1.8 meters) and a width of 8-12 feet (2.4-3.6 meters).

Building the Root Cellar Structure

To build a root cellar, start by excavating a pit in a well-draining area. Line the pit with 2-3 inches (5-7.5 cm) of compacted gravel, followed by a layer of 2-3 inches (5-7.5 cm) of sand. Install a waterproof liner, such as a plastic sheet or a waterproof membrane, to prevent moisture from entering the cellar. Next, build the walls using insulated concrete blocks, brick, or stone, and ensure they are at least 6 inches (15 cm) above the surrounding soil to prevent water from seeping in. The roof should be constructed with a minimum of 2 inches (5 cm) of insulation to maintain a consistent temperature.

Temperature and Humidity Control

To maintain the ideal temperature and humidity levels in the root cellar, consider installing a ventilation system that includes a solar-powered fan or a battery-powered dehumidifier. Ensure proper air circulation by installing vents or windows that allow fresh air to enter and stale air to escape. Additionally, store root cellar produce in a way that allows for airflow, such as using wire racks or hanging baskets, and keep the cellar clean and free of pests to prevent the buildup of moisture and odors.
