Storing homegrown onions can be a challenging task, especially for those who are new to gardening. Onions are a cool-season crop that can be grown in a variety of conditions, but they require proper storage to maintain their quality and freshness. In this article, we will explore the best methods for storing homegrown onions, including the preparation, storage options, and tips for maintaining their quality.
Preparing Onions for Storage
Before storing homegrown onions, it is essential to prepare them properly. This includes curing, drying, and cleaning the onions to remove any excess moisture and debris. Curing is a critical step in preparing onions for storage, as it helps to heal any wounds or damage to the skin, reducing the risk of rot and decay. To cure onions, place them in a warm, dry, well-ventilated area with the tops still attached. The temperature should be around 75-85°F (24-29°C), and the onions should be left to cure for 7-14 days.
Drying and Cleaning
After curing, the onions should be dried and cleaned to remove any excess moisture and debris. Use a soft brush or cloth to gently remove any dirt or debris from the skin, and then place the onions in a single layer on a wire rack or tray. Allow the onions to air dry for several hours or overnight, or use a fan to speed up the drying process.
Removing Tops and Roots
Once the onions are dry and clean, it is time to remove the tops and roots. Use a pair of scissors or a knife to trim the tops to about 1 inch (2.5 cm) above the bulb, and then removal the roots. This helps to prevent moisture from entering the bulb and reducing the risk of rot and decay.
Storage Options for Homegrown Onions
There are several storage options for homegrown onions, including cool, dry places, refrigeration, freezing, and root cellars. The best storage option will depend on the variety of onion, the climate, and personal preference.
Cool, Dry Places
One of the best storage options for homegrown onions is a cool, dry place. This can include a basement, cellar, or garage with a consistent temperature between 32-40°F (0-4°C) and low humidity. Onions should be stored in a single layer, either in a breathable bag or a ventilated container, to maintain airflow and prevent moisture buildup.
Refrigeration
Refrigeration is another storage option for homegrown onions, especially for smaller quantities. Onions can be stored in the refrigerator in a breathable bag or container, such as a paper bag or a ventilated plastic container. The refrigerator should be set at a consistent temperature below 40°F (4°C), and the onions should be checked regularly for signs of spoilage.
Freezing
Freezing is a great storage option for homegrown onions, especially for larger quantities. Onions can be frozen whole, chopped, or pureed, and then stored in airtight containers or freezer bags. To freeze onions, simply chop or puree them, and then place them in a single layer on a baking sheet. Once frozen, transfer the onions to an airtight container or freezer bag, and store them in the freezer at 0°F (-18°C) or below.
Root Cellars
A root cellar is a great storage option for homegrown onions, especially for those who have a lot of space. A root cellar is a cool, dark, humid environment that is ideal for storing onions and other root vegetables. The temperature should be consistent between 32-40°F (0-4°C), and the humidity should be around 80-90%.

By providing the right conditions, you can help to extend the storage life of your homegrown onions and keep them fresh for a longer period.
How should I prepare my homegrown onions for storage?
Before storing your homegrown onions, it is essential to prepare them properly. This involves curing the onions, which helps to dry out the outer skin and prevent moisture from entering the bulb. To cure onions, simply leave them in a warm, dry place with good air circulation for about two weeks. This will help to dry out the neck and outer skin, making them less prone to rot and spoilage. You can also trim the tops of the onions, leaving about an inch of stem intact, to help prevent moisture from entering the bulb.
Once the onions are cured, you can inspect them for any signs of damage or rot. Remove any damaged or rotten onions, as these can spoil the rest of the batch. Gently dust off any excess dirt or debris, and then place the onions in your chosen storage container. It is essential to handle the onions carefully to avoid damaging them, as this can lead to rot and spoilage. By preparing your homegrown onions properly, you can help to ensure they remain fresh and healthy throughout the storage period.
What are the best containers for storing homegrown onions?
When it comes to storing homegrown onions, the right container can make a big difference. The best containers for storing onions are those that allow for good air circulation and are breathable. Paper bags, mesh bags, and cardboard boxes with holes are all excellent options. These types of containers will help to keep the onions dry and cool, while also preventing the buildup of moisture. Avoid using airtight containers, such as plastic bags or containers, as these can trap moisture and lead to rot and spoilage.
In addition to using the right type of container, it is also essential to ensure that the onions are not overcrowded. Overcrowding can lead to increased moisture and humidity, which can cause the onions to rot and spoil. Store the onions in a single layer, with enough space between each bulb to allow for good air circulation.

By using the right container and storing the onions correctly, you can help to keep them fresh for a longer period.
Can I store homegrown onions in the refrigerator?
While it may be tempting to store homegrown onions in the refrigerator, this is not the best option. Onions are sensitive to moisture and ethylene gas, which is produced by many types of fruit and vegetables. The refrigerator is typically too humid for onions, and the ethylene gas can cause them to spoil more quickly. Additionally, the cold temperature can cause the onions to become bitter and lose their flavor. If you must store onions in the refrigerator, make sure to keep them away from other fruits and vegetables, and use a breathable container or bag to help maintain airflow.
Instead of storing onions in the refrigerator, it is better to store them in a cool, dry place with good air circulation. A pantry, cupboard, or shed can be an ideal location, as long as it is away from direct sunlight and moisture. You can also consider storing onions in a root cellar or basement, as these areas are often cool and dry. By storing your homegrown onions in the right location, you can help to keep them fresh for a longer period and prevent them from spoiling. Remember to check on the onions regularly to ensure they are not developing any signs of rot or spoilage.
How long can I store homegrown onions?
The storage life of homegrown onions depends on several factors, including the variety, storage conditions, and handling. Generally, homegrown onions can be stored for several months, with some varieties lasting up to 6 months or more. Onions that are high in sulfur, such as yellow and white onions, tend to store better than those that are low in sulfur, such as red and sweet onions. To maximize the storage life of your homegrown onions, make sure to provide them with the right conditions, handle them carefully, and check on them regularly.
To get the most out of your stored onions, it is essential to use the older ones first. Onions that are closer to sprouting or developing green shoots should be used sooner, as they will not store as well as those that are still firm and dry. Check on the onions regularly to remove any that are developing signs of rot or spoilage, as these can quickly spread to the rest of the batch. By storing your homegrown onions correctly and using them in a timely manner, you can enjoy them throughout the year and make the most of your harvest.
Can I store homegrown onions with other vegetables?
While it may be convenient to store homegrown onions with other vegetables, this is not always the best option. Onions can absorb moisture and odors from other vegetables, which can cause them to spoil more quickly. Additionally, some vegetables, such as potatoes and carrots, can release ethylene gas, which can cause the onions to ripen and spoil more quickly. If you must store onions with other vegetables, make sure to keep them separate and use a breathable container or bag to help maintain airflow.
It is generally best to store homegrown onions separately from other vegetables, as this will help to maintain their quality and prevent them from spoiling. If you have limited storage space, consider storing onions in a separate area or container, such as a paper bag or mesh bag. This will help to keep them dry and cool, while also preventing them from absorbing moisture and odors from other vegetables. By storing your homegrown onions separately, you can help to keep them fresh for a longer period and enjoy them at their best.
How can I tell if my stored homegrown onions have gone bad?
To determine if your stored homegrown onions have gone bad, look for signs of rot, mold, or sprouting. Onions that are developing green shoots or have soft, mushy spots should be discarded, as they are no longer safe to eat. You can also check the onions for any signs of moisture or wetness, as this can indicate that they are spoiling. If you notice any of these signs, remove the affected onions immediately to prevent the rest of the batch from spoiling.
In addition to checking for visible signs of spoilage, you can also use your sense of smell to determine if your stored onions have gone bad. Onions that are spoiling will often give off a strong, unpleasant odor, which can be a sign that they are no longer safe to eat. If you notice any off-odors or flavors, it is best to err on the side of caution and discard the onions. By regularly checking your stored onions and removing any that are spoiling, you can help to maintain their quality and ensure they remain safe to eat.
