Should I use plastic or wood containers for root cellar storage?

April 5, 2026

Quick Answer

Plastic containers are not recommended for root cellar storage due to their poor insulation properties and potential for moisture accumulation, which can lead to mold and root rot. Wood containers, on the other hand, can be a suitable option with proper treatment and maintenance to prevent decay.

Choosing the Right Wood for Root Cellar Storage

When it comes to selecting wood for root cellar containers, durability and rot resistance are crucial. Cedar, cypress, and redwood are excellent choices due to their natural oils that repel insects and moisture. Use 2x4 or 2x6 lumber for the walls and shelves, and consider using a waterproof glue and nails to seal any gaps.

Designing the Root Cellar Container

A well-designed root cellar container should maintain a consistent temperature between 32-40°F (0-4°C) to slow down spoilage and extend the storage life of your produce. Aim for a minimum thickness of 2-3 inches (5-7.5 cm) for the walls and floor to provide adequate insulation. Consider adding a lid or cover to regulate humidity and maintain a consistent temperature.

Maintaining the Root Cellar Container

Regular maintenance is essential to keep your root cellar container in good condition. Check the wood for signs of decay or rot, and apply a waterproof sealant as needed. Also, make sure to ventilate the container to prevent moisture buildup and maintain a healthy environment for your stored produce.
