To stop garlic from growing, specifically preventing sprouting or root growth during storage, you need to store it under specific conditions that inhibit this process.
Based on effective storage practices, the key is controlling the environment around the garlic bulbs. This primarily involves managing light, air circulation, and humidity.
Optimal Storage Conditions to Prevent Garlic Growth
The most effective way to prevent garlic from sprouting and developing roots is by providing the correct storage environment.
-
Darkness: Keeping garlic in a dark place helps prevent the bulb from receiving the light signals that can encourage sprouting. While not strictly essential, it is generally recommended.
-
Good Air Circulation: Proper airflow is crucial. It helps to regulate temperature and humidity around the bulbs, preventing moisture build-up which can lead to mold or sprouting.
-
Controlled Humidity: Humidity is a critical factor in preventing root growth.
Also, it is best to keep your garlic in a dark place when possible (although not completely necessary) with good air circulation, especially in more humid conditions. Humidity between 45% and 50% (similar to conditions in many homes) is high enough to minimize dehydration and low enough to prevent root growth.
Storing garlic within this specific humidity range (45%-50%) provides a balance: it helps prevent the bulbs from drying out too quickly (minimizing dehydration) while crucially keeping the environment dry enough to inhibit the development of roots.
Practical Storage Tips
- Store garlic bulbs whole; separating cloves can shorten their lifespan and encourage sprouting.
- Use mesh bags, paper bags, or open baskets that allow for good air circulation. Avoid plastic bags or sealed containers.
- Find a cool, dry location away from direct sunlight and sources of heat, such as an unheated pantry, cellar, or cupboard. Kitchen counters are often too warm and bright unless specifically located in a cool, dark spot.
- Maintain the humidity level if possible. While measuring humidity might not be practical for everyone, aiming for average household humidity levels (around 45-50%) is generally effective.
By controlling these environmental factors, particularly humidity and airflow in a dark space, you can significantly slow down or stop the natural growth process of garlic bulbs after harvest, keeping them dormant and ready for use for a longer period.
