How to Store Onions Until Spring: An Effective Method from Experienced Gardeners

Proper storage of onions after harvest is key to preserving their flavor and beneficial properties throughout the winter. Many gardeners find that by the beginning of the year, their supplies start to spoil, making it impossible to save them. To avoid losses, it is important to follow the basic recommendations for storing onions at home.

Optimal Conditions for Long-Term Onion Storage

Onions can be stored for up to 10 months if the correct temperature and humidity are maintained. Ideally, a temperature of +18 to +22 degrees Celsius with low humidity is suitable for home storage. If the harvest is placed in a dry cellar, the optimal temperature is between 0 and +3 degrees Celsius. Adhering to these conditions allows the produce to be kept until the new season with minimal losses.

A Simple Method to Extend Onion Shelf Life

The storage location—be it a cellar, garage, apartment, or even a balcony—is not crucial if a simple trick is applied. Experienced gardeners recommend “searing” the roots and neck of each onion. This can be done easily with a regular candle: lightly scorching these parts of the vegetable helps, as experts say, to “seal” the juices inside the onion, preventing the produce from drying out and rotting for an extended period.

Following simple advice regarding temperature, humidity, and a special approach to treating the onions allows for easy storage of the vegetable until spring without unnecessary difficulties and crop losses.
