Hanging / Storing Onions

Hi folks

Would you agree with the comment below?

You hang onions initially to let any remaining nutrients in the leaves drain back into the onions. That increases the time they can be stored. (So many people this year have dried theirs on wire mesh with the leaves hanging down below the onions, which allows nothing to drain into the bulbs and weakens the bulb.)

Then, when all the green has gone from the leaves, either plaiting them together or tying them to string to hang in a cool dry place will allow them to be stored for the longest time.
