Stores well for winter.
Local Grown Winter Keeper Onions are heirloom or hybrid onion varieties that have proven to hold up well under long-term storage.
These onions typically have thicker outer skins, a higher sulphur content and a lower water content than most other onions.
Choose a cool, dry, dark place to store them. Most storage onions last at least 8 months, but some can last up to 12 months.
Inspect your onions regularly, and discard any that show signs of mold or rot.
