drying onions

I would leave them in the soil as long as its dry. Mine also seem to be starting to ripen early than normal this year. Last year i dried them off in my cold greenhouse with the window and door open all day and night and then strung them up. They lasted all winter.

For what it's worth I'm digging mine up a few everyday .

Plenty of air passing round them to blow away any surface moisture is best too.

I place mine in a gravel tray and they go out on the garden table top during dry days and live in the shed on wet days and nights. then when ready get tied in bunches and hung in the shed.

My onions are starting to fall over so will need lifting and drying soon. I have an open lean-to w2hich is I the shade so they would get dry coolish conditions there rather than full sun which is very powerful and hot. Which is the best option for drying them? A few years back I left them in the ground until the tops were nearly dry before lifting and they did well then but it was much later in the year when the matured that year. I don't want to cook them

Last year I made the mistake of leaving them under the transparent roof of the open sided shelter, and they did get slightly "cooked" *, so this year Mr S made a wooden frame on blocks, covered with debris netting to give enough air circulation, and so far the Autumn planted onions have dried off very well out in the open. The frame will be pressed into service again very soon for the Summer crop. It does take two of us to move it under the shelter if it is raining though, as the onions are so heavy.
