Harvest green onions as soon as they reach your preferred size.
Leave bulb onions for storage in the ground until the tops die. Over-wintered bulb onions are ready to harvest in June.
As onions are thinned, uprooted onions may be used as green onions.
Bolting may occur under cold weather stress. If onions bolt, the bulb rapidly deteriorates. Harvest and use as soon as possible.
For winter storage, harvest the onion crops after the tops have dried up.
Storage and Preservation Methods
For storage, place freshly harvested onions where they will have good air circulation for at least two weeks while the outer skin cures.
Onions can be frozen but lose some flavor in freezing.
They are often canned as part of mixed dishes.
