Could someone tell me how long you have to hang onions , before eating them.
10 seconds. they're ready to go the minute you lift them. even if the tops are still green. don't plait them together unless thr tops are fully dry, brown and crinkly sounding.
how would you suggest to store them. Would it be a good idea to take of the tops so they do not make the onions go rotten if they are damp.
You can store them anywhere cool and dry. You dry the tops if you're going to plait them. Otherwise don't cut the tops too close to the onion itself or you can risk disease.
You do not have to plait them. You can store them in plastic trays, in boxes, wherever you want. Leave them to fully dry in the greenhouse, on the garage floor, workbench or on a wire frame under cover.
I just tie mine together and hang from a nail or hook,need to be dry and airy.
