Project Overview: The DIY Root Cellar

A root cellar is a naturally cooled storage space, traditionally built partially or entirely underground, used to preserve fruits, vegetables, and other foods for long periods without the need for electricity. For homesteaders, a DIY root cellar offers a multitude of benefits:

• Increased Self-Sufficiency: Store your harvest for months, reducing your reliance on grocery stores and commercially produced food.
• Reduced Environmental Impact: Eliminate the need for energy-intensive refrigeration for many of your crops.
• Cost Savings: Save money on your grocery bill by preserving your own food.
• Enhanced Food Quality: Properly stored produce in a root cellar often retains more nutrients and flavor compared to refrigerated items.
• Resilience: Build a food storage system that is independent of the power grid, ensuring food security in times of emergency.

This guide provides clear and easily understandable instructions suitable for beginner to intermediate homesteaders to construct their own functional and efficient root cellar. While a larger, fully underground cellar is a significant undertaking, this design focuses on a smaller, partially buried structure that's easier to build and maintain. We will focus on using readily available and affordable materials.

Step-by-Step Instructions

Step 1: Planning and Design

1. Assess Your Needs: Determine the amount of storage space you require based on the size of your garden and the types of produce you plan to store. Consider the climate in your area and the desired temperature and humidity levels for optimal storage. On average, a root cellar temperature should remain between 32 and 40 degrees Fahrenheit with high humidity. Different vegetables require different humidity levels. Carrots and potatoes like high humidity, while onions and garlic prefer dry conditions.

2. Choose a Location: Select a location that is naturally cool and shaded, preferably on the north side of a building or under trees. The site should have good drainage to prevent water from accumulating around the root cellar. Avoid areas prone to flooding or with high water tables. A slight slope is ideal for drainage.

3. Design Your Root Cellar: This guide focuses on a partially buried root cellar, approximately 6ft wide, 8ft long, and 4ft high (internal dimensions). Adjust these dimensions to suit your needs, but remember that larger cellars require more materials and labor. Plan for ventilation, insulation, and access (door).

4. Obtain Necessary Permits: Check with your local building department to determine if any permits are required for constructing a root cellar on your property.

Tips and Troubleshooting:

• Proper planning is crucial for a successful root cellar. Take your time to assess your needs, choose the right location, and design a structure that meets your requirements.
• Consider consulting with a local builder or experienced homesteader for advice on design and construction techniques.

Material List:

• Treated Lumber (for framing) - Amount depends on your specific design. Calculate accordingly.
• Plywood or OSB (for sheathing) - Enough to cover the frame.
• Rigid Foam Insulation (for walls and roof) - R-value of at least R-13.
• Gravel (for drainage) - Approximately 2 cubic yards.
• Concrete Blocks (for foundation, optional) - Amount depends on foundation design.
• Plastic Sheeting (vapor barrier) - Enough to cover the entire structure.
• Door (salvaged or new) - One standard-sized exterior door.
• Ventilation Pipes (PVC or metal) - Two 4-inch diameter pipes.
• Hardware (nails, screws, fasteners) - Assorted sizes and types.
• Topsoil (for covering the structure) - Enough to cover the roof and walls with at least 12 inches of soil. Source locally if possible.

Tool List:

• Shovel
• Level
• Measuring Tape
• Circular Saw
• Drill
• Hammer
• Staple Gun
• Utility Knife
• Wheelbarrow
• Tamper

Safety Precautions:

• Wear safety glasses when cutting wood or working with power tools.
• Use gloves to protect your hands.
• Be aware of underground utilities before digging.
• Work with a partner when lifting heavy materials.

Step 2: Prepare the Foundation

1. Clear the Area: Remove all vegetation and debris from the 6ft x 8ft area designated for your root cellar foundation. A clear foundation ensures proper leveling and prevents rotting vegetation from attracting pests.

   

2. Level the Ground: Using a level and shovel, level the ground. Compact the soil with a tamper. A level foundation ensures stability and prevents future problems. Take your time to ensure proper leveling; it will pay off later.

   

3. Add Gravel Base: Pour a 6-inch layer of gravel over the leveled area. This provides drainage and prevents moisture buildup. Spread the gravel evenly and compact it again. Good drainage is critical to prevent moisture from seeping into your root cellar.

   

Tips and Troubleshooting:

• If the soil is particularly unstable, consider building a simple concrete block foundation to provide additional support.
• Use a plate compactor for optimal soil compaction.
• Ensure the gravel base extends slightly beyond the footprint of the root cellar to facilitate drainage.

Step 3: Build the Frame

1. Construct the Walls: Build the wall frames using treated lumber. The walls should be 4ft high. Ensure the frames are square and sturdy. Use appropriate fasteners (nails or screws) for structural integrity.
2. Construct the Roof Frame: Build a slightly sloped roof frame to allow for water runoff. A slight angle is all you need. The slope can be achieved by making one wall slightly taller than the opposite wall.
3. Attach Sheathing: Cover the wall and roof frames with plywood or OSB sheathing. This provides structural support and a surface for attaching insulation.

Tips and Troubleshooting:

• Use pressure-treated lumber for all parts of the frame that will be in contact with the ground.
• Ensure all connections are strong and secure.
• Consider adding diagonal bracing to the walls for increased stability.

Step 4: Insulate and Waterproof

1. Install Insulation: Attach rigid foam insulation to the inside of the walls and roof. Use construction adhesive and fasteners to secure the insulation in place. Seal all seams and gaps with insulation tape. Homesteading insulation is key to maintaining the proper temperature in your cellar.
2. Install Vapor Barrier: Cover the insulation with a plastic vapor barrier to prevent moisture from entering the structure. Overlap the seams of the vapor barrier and seal them with tape.
3. Waterproof the Exterior: Apply a waterproof membrane to the exterior of the walls and roof to protect the structure from moisture. This can be a liquid-applied membrane or a self-adhesive membrane.

Tips and Troubleshooting:

• Use the highest R-value insulation you can afford for optimal temperature control.
• Pay close attention to sealing all seams and gaps in the insulation and vapor barrier.
• Ensure the waterproof membrane is properly applied and covers all exposed surfaces.

Step 5: Install the Door and Ventilation

1. Install the Door: Frame the door opening and install a sturdy exterior door. Ensure the door is properly sealed to prevent drafts and moisture from entering the root cellar.
2. Install Ventilation: Install two ventilation pipes – one near the floor and one near the ceiling. This allows for air circulation and helps to regulate temperature and humidity. The pipes should extend above the ground surface. A properly designed gray water system design can be integrated into the drainage plan around the root cellar, but this requires careful planning and local code compliance.

Tips and Troubleshooting:

• Use a weather-stripped door to minimize drafts.
• Install screens on the ventilation pipes to prevent insects and rodents from entering the root cellar.
• Consider installing a damper on the ventilation pipes to control airflow.

Step 6: Bury the Root Cellar

1. Backfill the Sides: Backfill the sides of the root cellar with soil, compacting it as you go. Ensure the soil is sloped away from the structure to promote drainage.
2. Cover the Roof: Cover the roof with at least 12 inches of topsoil. This provides insulation and helps to maintain a stable temperature inside the root cellar.
3. Plant Vegetation: Plant grass or other vegetation on top of the soil to help stabilize the soil and provide additional insulation. Barn restoration tips often include planting vegetation around the base to control erosion and temperature.

Tips and Troubleshooting:

• Avoid using heavy machinery to backfill the sides of the root cellar, as this could damage the structure.
• Compact the soil in layers to prevent settling.
• Choose vegetation that is drought-tolerant and requires minimal maintenance.

Step 7: Interior Finishing and Storage

1. Install Shelving: Build or install shelving inside the root cellar to provide storage for your produce. Use sturdy materials that can withstand the weight of the stored items.
2. Organize Your Storage: Organize your produce by type and storage requirements. Use containers that allow for air circulation. Consider adding a thermometer and hygrometer to monitor the temperature and humidity inside the root cellar.

Tips and Troubleshooting:

• Leave space between shelves to allow for air circulation.
• Rotate your produce regularly to prevent spoilage.
• Clean the root cellar regularly to prevent mold and mildew growth. DIY root cellar maintenance is critical for long-term success.
