When to pull my onions?

[JerryL]

This is the first year I have had any success growing onions.

I’ve read a couple of articles that say they are ready to pull ‘when the tops turn brown and fall over’. I’m used to seeing this with the garlic I grow. However, my onion tops are falling over but are still green. The bulbs are all good size and lifting out of the ground.

Should I wait for the tops to turn brown or should I pull them now?

Thanks for any help.
