Why a Freezer Root Cellar?

Traditional root cellars are fantastic, but they can be expensive and time-consuming to build. A repurposed freezer offers several advantages:

• Cost-Effective: You can often find used freezers for free or at a very low price.
• Easy to Build: Minimal construction skills are required.
• Temperature Control: The freezer's insulation helps maintain a stable temperature.
• Portable: It can be moved if needed (before you bury it!).
• Space-Saving: Perfect for smaller homesteads or gardens.
• Upcycling: Giving a new life to an appliance that would otherwise end up in a landfill.

Choosing the Right Freezer

The ideal freezer for a DIY root cellar is a chest freezer. Avoid upright freezers, as they are less efficient at maintaining a consistent temperature and are more difficult to bury. Look for a freezer that is:

• In good condition: The insulation should be intact, and the lid should seal properly.
• The right size: Consider the amount of produce you want to store. A medium-sized freezer (10-15 cubic feet) is usually sufficient for a small family.
• Clean: Thoroughly clean the freezer before starting any modifications.

Important: Ensure the freezer is no longer functional and poses no electrical hazards. Remove the power cord completely.

Step-by-Step Guide: Building Your Freezer Root Cellar

Here's a detailed, step-by-step guide to building your own cheap root cellar from a repurposed freezer.

Step 1: Preparing the Site

Choose a location carefully. The ideal location for your DIY root cellar should be:

• Well-drained: Avoid areas prone to flooding or standing water.
• Shaded: A north-facing slope is best to minimize temperature fluctuations.
• Accessible: Easy to reach from your garden.
• Consider Proximity to your house: Minimizes trips in cold weather.

Dig a hole that is slightly larger than the freezer. The top of the freezer should be about 12-18 inches below the ground level. This helps maintain a consistent temperature and protects it from freezing.

Why this is important: Proper site selection and preparation are crucial for the success of your root cellar. Good drainage prevents water from damaging your produce, while shade helps maintain a cool temperature.

Step 2: Preparing the Freezer

• Remove the Door Latch: To prevent accidental entrapment, remove or disable the freezer's latch. Safety First!
• Drill Drainage Holes: Drill several (at least 6-8) drainage holes in the bottom of the freezer. This will prevent water from accumulating inside.
• Ventilation: Create a ventilation system. This is critical for preventing mold and maintaining air circulation. The easiest method is to install a PVC pipe (4-inch diameter) through the lid. Extend the pipe several inches above the ground. Cover the top with a screen to keep out insects and rodents.

Materials for Ventilation:

• 4-inch PVC pipe (length depends on burial depth) - $5
• PVC pipe connector - $2
• Screening material - $3
• PVC cement - $5 (optional, for a more secure connection)

Drill a hole in the top for the PVC pipe. Secure it with sealant to prevent water from leaking in.

Why this is important: Ventilation is essential for preventing moisture buildup and mold growth inside the root cellar. Drainage holes prevent water from pooling at the bottom.

Step 3: Installing the Freezer

• Lower the freezer into the hole: Use straps or ropes to carefully lower the freezer into the prepared hole.
• Level the freezer: Ensure the freezer is level. Use shims if necessary.
• Backfill around the freezer: Backfill the hole with soil, compacting it as you go. Leave the top of the freezer exposed.
• Insulate the Lid: Insulate the lid with straw bales, old blankets, or rigid foam insulation. This will further protect your produce from temperature fluctuations. Cover with a waterproof tarp to prevent water damage.
• Camouflage: Optional, to make it less obvious, camouflage the lid with plants or rocks.

Why this is important: Proper insulation is key to maintaining a stable temperature inside the root cellar. Camouflaging the lid can help protect it from the elements and deter unwanted attention.

Step 4: Creating Internal Shelving (Optional)

• Build simple shelves: Use recycled wood or pallets to create simple shelves inside the freezer. This will help organize your produce and improve air circulation.

Materials List (Estimated Prices):

• Used chest freezer (check online marketplaces or appliance repair shops) - $0-$50
• 4-inch PVC pipe for ventilation - $5
• PVC pipe connector - $2
• Screening material - $3
• Gravel for drainage - $10 (depending on quantity needed)
• Recycled wood or pallets for shelving (optional) - $0
• Straw bales or old blankets for insulation - $0-$20
• Waterproof tarp - $15
• Sealant - $7
• Total Estimated Cost: $42 - $112 (depending on the freezer cost and materials on hand)

Alternative options:

• Instead of PVC pipe, you could use a repurposed metal pipe.
• Instead of straw bales, you could use leaves or other organic material for insulation.
• Check with local businesses for free pallets or scrap wood.

Common Challenges and Solutions

• Moisture: Ensure adequate ventilation to prevent moisture buildup. Consider adding a desiccant, such as calcium chloride, to absorb excess moisture.
• Pests: Seal any cracks or openings to prevent rodents and insects from entering. Use traps if necessary.
• Freezing: In very cold climates, add extra insulation to the lid and consider burying the freezer deeper.
• Temperature Fluctuations: Monitor the temperature inside the root cellar regularly. Add or remove insulation as needed to maintain a stable temperature.

What to Store in Your Freezer Root Cellar

The best vegetables to store in a freezer root cellar are root vegetables, such as:

• Potatoes
• Carrots
• Beets
• Turnips
• Parsnips
• Cabbage
• Onions
• Garlic
• Apples (some varieties)

Bonus Tip: Maximize Lifespan

Don't wash your vegetables before storing them. A light coating of dirt actually helps to protect them. Store vegetables in layers of damp sand or sawdust to maintain moisture and prevent them from drying out.

Conclusion

Building a DIY root cellar from a repurposed freezer is a simple, affordable, and effective way to extend your harvest and enjoy fresh, homegrown produce throughout the winter. It’s a rewarding project that aligns with the values of self-sufficiency, sustainability, and community. By following these steps, Sarah (and you!) can enjoy the delicious fruits (and vegetables) of her labor all year long.
