When to Pick Pick onions and shallots once all of their leaves have fallen over naturally. Lift carefully from soil and let dry for about a week in a warm dry place. This may be done in your garden bed, but should only been done when the weather is dry and mild. Leave in the ground a few onions or shallots to winter over and come back in the spring.
Drying You’ll know the onions are done drying when they have the papery brittle outer skins, like the store bought onions, but you didn’t grow em! The roots will be dry, and the tops will be completely dried out.
Storing Brush off excess dirt and you are ready to braid! Cut three pieces of twine about 3 feet long and tie them together at one end. Then braid twine and onion tops together, until within 6 inches of the of the twine. Wrap one piece of twine fast around the onions stems, then tie to the other two and hang in a dark, dry, cool place. This same practice can be done with harvested and dried garlic to keep for many months.
