Quick Answer
Store potatoes in a root cellar with temperatures between 32 and 40 degrees Fahrenheit and humidity levels between 80 and 90 percent. Keep them in the dark or with a dim red light to prevent sprouting. Regularly check on the potatoes for signs of rot or decay.
Choosing the Right Potatoes
When selecting potatoes for storage in a root cellar, look for varieties that are specifically bred for long-term storage, such as ‘Russet’, ‘Idaho’, or ‘Yukon Gold’. These varieties tend to have a thicker skin and a lower moisture content, which helps to prevent spoilage. Select potatoes that are firm and free of bruises or eyes that have started to sprout.
Root Cellar Design and Temperature Control
A well-designed root cellar can maintain a consistent temperature between 32 and 40 degrees Fahrenheit, which is ideal for storing potatoes. The temperature should be maintained at a consistent level, with minimal fluctuations throughout the day. This can be achieved through the use of insulation, such as foam board or straw bales, and a consistent ventilation system. Aim to maintain a temperature of around 35 degrees Fahrenheit for optimal storage.
Storage Techniques and Humidity Control
Store potatoes in a breathable container, such as a mesh bag or a wire basket, to allow for air circulation and to prevent moisture buildup. Keep the potatoes away from direct sunlight and heat sources, such as radiators or heating vents. Maintain a humidity level between 80 and 90 percent in the root cellar by using a humidistat or by placing a tray of water in the cellar. Check on the potatoes regularly for signs of spoilage and remove any potatoes that show signs of decay.
