Quick Answer
A root cellar is ideal for storing herbs that thrive in cool, humid conditions, such as parsley, chives, and mint. Other herbs like sage and thyme can also be stored successfully in a root cellar. When selecting herbs for storage, choose those with thick, fleshy leaves and stems.
Choosing the Right Herbs for Storage
When selecting herbs for storage in a root cellar, look for plants with thick, fleshy leaves and stems that can tolerate cooler temperatures. Herbs like parsley, chives, and mint are ideal for root cellars due to their ability to grow in moist environments. For example, parsley prefers temperatures between 35°F and 45°F (2°C and 7°C) and humidity levels above 80%. Chives, on the other hand, can tolerate temperatures as low as 25°F (-4°C) and humidity levels around 70%.
Harvesting and Storing Herbs
To store herbs successfully in a root cellar, harvest them at the right time. For most herbs, this means cutting back the stems to about an inch from the base of the plant. Trim the leaves to about an inch from the stems to promote new growth and prevent moisture from accumulating. Store the herbs in a breathable container, such as a mesh bag or a paper towel, to maintain airflow and prevent mold growth. Place the container in the root cellar, where the herbs will remain fresh for several weeks.
Maintaining Optimal Conditions
To maintain optimal conditions for herb storage in a root cellar, ensure the temperature remains between 32°F and 40°F (0°C and 4°C). Humidity levels should be maintained above 80% to prevent the herbs from drying out. Good ventilation is also crucial to prevent the buildup of ethylene gas, which can cause the herbs to spoil. To achieve these conditions, use a temperature control system and install a ventilation system that includes a dehumidifier and a fan to circulate the air.
