If you plan to store the pungent bulbs for winter use, curing onions is a necessary step in the process. Without proper curing, onion bulbs turn soft and mushy.

How do you know when onions are ready?
Three Signs Your Onions are Ready for Harvest
- Soft Neck. When the area right above the neck (the place where the leaves meet the bulb) starts feeling soft, the transfer of carbohydrates from the leaves to the rings has finished meaning the final cell division within the rings has occurred.
