By the end, you’ll have expert-backed strategies to keep your onions fresh, flavorful, and ready to use when you need them.
When and How to Harvest Onions from the Garden
Harvest timing and technique are the foundation of good onion storage.
- Harvest at the right time: Onions are ready when their tops (leaves) begin to yellow and fall over naturally. This indicates the bulb has matured.
- Avoid harvesting wet onions: Wet conditions promote rot. Wait for dry weather before pulling onions.
- Handle gently: Pull onions by the base, and avoid bruising or cutting the bulb skin.
Expert Tip: Leave onions in the garden for a day or two after tops fall over to allow skins to dry slightly, but avoid leaving them too long as bulbs can split.
The Importance of Curing Onions Before Storage
Curing is a critical step that prepares onions for long-term storage by drying the outer layers and neck.
How to Cure Onions Properly:
- Lay onions out in a single layer in a dry, well-ventilated spot, away from direct sunlight.
- Ideal temperature: 75-80°F (24-27°C) with low humidity.
- Curing duration: 2-3 weeks or until the necks are completely dry and papery.
- Flip onions occasionally to promote even drying.
Why cure?
Curing seals the onion’s outer skin, preventing moisture loss and reducing the risk of mold or rot during storage.
Best Storage Conditions for Onions From the Garden
After curing, store onions in ideal conditions to maximize shelf life.
Key Requirements:
- Temperature: 32-40°F (0-4°C) is optimal for long-term storage.
- Humidity: Keep humidity around 65-70% to prevent onions from drying out or sprouting.
- Air circulation: Good ventilation is vital. Avoid plastic bags or sealed containers.
- Light: Store onions in a dark or dimly lit place to prevent sprouting.
Storage Options:
- Mesh bags or burlap sacks: Allow air to circulate freely.
- Hanging braids: Traditional method using onion tops braided together.
- Wooden crates or slatted boxes: Provide airflow while protecting onions from crushing.
Common Mistakes to Avoid When Storing Onions
- Storing near potatoes: Potatoes release moisture and gases that cause onions to spoil faster.
- Ignoring damaged onions: Remove any bruised or soft bulbs before storage to prevent spread of rot.
- High humidity storage: Excess moisture causes onions to rot or sprout prematurely.
- Poor ventilation: Storing onions in airtight containers traps moisture and promotes mold growth.
How Long Can You Store Garden Onions?
With proper curing and storage, garden onions can last:
- Dry onions: 3 to 6 months
- Sweet or soft-neck onions: Up to 2 months (due to higher water content)
For longer storage, check onions frequently and remove any that show signs of sprouting or spoilage.
Tips for Extending Onion Shelf Life
- Use onion varieties suited for storage: Varieties like Yellow Globe or Walla Walla store better than sweet onions.
- Regularly inspect stored onions: Remove spoiled bulbs immediately.
- Refrigerate cut onions: Once cut, onions should be refrigerated in airtight containers and used within a week.
- Freeze or dehydrate excess onions: For extended use beyond storage limits, consider freezing chopped onions or dehydrating them for powders.
