Lift onions only when the leaves are quite dry. It is best to lift your onions when it is not raining, so that they will not rot.
Leave the onions Iying on the field for a few days, so as to dry them well. It is best to cover them up with a little grass or straw. If it rains, dry the onions under a shelter.
To keep onions well, store them in a dry, airy place, well protected against rats and other animals.
