We’ve been harvesting onions for over a month as the greens wilt and fall over. We leave them on the back porch to dry. They’ve dried out, but the moist air is not good, and It’s raining, so I can do some onion cleaning in the meantime. Then I take them down to the food room in the basement to dry out more and for winter storage. They usually stay good all winter and spring – until the following year’s onions start getting going. The last straglers go on the compost as the new ones are better and fresher.
