Build A Root Cellar Outdoors

Building a Root Cellar Outdoors

A root cellar is a valuable asset for gardeners and anyone interested in preserving food. It provides a cool, dark, and humid environment ideal for storing root vegetables, fruits, and other perishable foods for extended periods. Building an outdoor root cellar can be a rewarding project that enhances self-sufficiency and reduces reliance on grocery stores. This article explores the essential steps involved in constructing a root cellar outdoors, providing practical guidelines for achieving a successful build.

Site Selection and Preparation

The first step in building a root cellar is selecting a suitable location. The ideal site should meet the following criteria:

North-facing slope: A slope that faces north provides shade and helps maintain a cooler temperature inside the cellar.
Well-drained soil: Avoid areas prone to flooding or standing water, as this can compromise the structure and create moisture problems within the cellar.
Good drainage: Ensure proper drainage to prevent water from accumulating around the cellar, which can damage the structure and lead to mold growth.
Easy access: Choose a location that is easily accessible for loading and unloading stored items.

Once the site is chosen, prepare the area by removing any vegetation, debris, and rocks. The ground should be leveled and compacted to provide a stable foundation for the cellar.

Construction Techniques

Several construction techniques can be used to build an outdoor root cellar. The most common methods include:

1. Concrete Block Construction

This method involves using concrete blocks to create the walls and roof of the cellar. Concrete blocks are durable, affordable, and readily available. The construction process involves stacking the blocks, using mortar to bind them together, and adding a concrete slab for the floor. This method is suitable for experienced builders and those with access to the necessary tools and materials.

2. Earth-Bermed Construction

Earth-bermed construction involves excavating a pit and then building a structure within the pit using concrete blocks, timber, or other materials. The structure is then covered with earth, creating a berm that insulates the cellar and helps maintain a cool temperature. This method offers excellent insulation and is relatively easy to construct.

3. Log Cabin Construction

Log cabin construction utilizes logs to create the walls of the cellar. The logs are stacked and secured using a variety of techniques, such as dovetail joints or mortise and tenon joints. This method offers a rustic aesthetic and excellent insulation, but it requires skilled carpentry and access to suitable logs.

Essential Features

Regardless of the construction method chosen, several essential features are crucial for a successful root cellar:

1. Ventilation

Proper ventilation is essential for maintaining a healthy environment inside the cellar. It helps prevent the buildup of moisture, odors, and gases. A ventilation system typically consists of two vents: one at the top for exhaust and another at the bottom for fresh air intake. The vents should be positioned strategically to ensure proper airflow.

2. Insulation

Insulation is crucial for maintaining a stable temperature inside the cellar. Insulation materials such as foam board, fiberglass, or straw can be used to line the walls and ceiling, reducing heat transfer and maintaining a cool environment.

3. Moisture Control

Moisture control is critical for preventing mold and mildew growth. A dehumidifier can be installed to remove excess moisture from the air. Additionally, a gravel layer beneath the floor can help improve drainage and prevent moisture buildup.

4. Shelving and Storage

Appropriate shelving and storage systems are essential for organizing and storing produce. Shelves should be adjustable to accommodate different sizes of fruits and vegetables. Bins, crates, and other containers can be used to store specific items and prevent them from touching the floor.

Building an outdoor root cellar requires careful planning, meticulous execution, and a commitment to providing an environment that meets the specific needs of food preservation. By following these guidelines and considering the essential features discussed, you can build a lasting and valuable asset for storing and preserving food, enhancing self-sufficiency and ensuring access to fresh and healthy produce throughout the year.
