Harvest onions

It’s time to think about harvesting main crop onions from the garden. The exact time to lift the bulbs will depend on the variety you are growing, where you live and when you planted.
I like to keep my plants in the ground for as long as possible so the bulbs get to a decent size, so I usually start lifting around this time.
It’s vital that the bulbs are allowed to ripen as much as possible, especially if you want to store the onions for use over the winter months. If lifted and stored when they are green, the bulbs will soon start to deteriorate.
When the foliage on my onions started to turn yellow and die back naturally a couple of weeks ago, I bent the tops over to allow
more light and sun to get
to the bulbs.
Once the tops have completely died and the outer skin on the bulbs has dried to a brown colour, it is time to lift the bulbs. If you leave them in the ground for much longer there’s a chance of rots setting in, especially if the weather is cool and damp.
As for storing onions, they should keep for several months or even longer as long as the bulbs are ripe and sound. Any bulbs that have been damaged with a hoe or when they’ve been lifted shouldn’t be stored. They should be used at once.
Also bear in mind that onions with thick necks do not last for long.
