A quick google confirms I’m chatting shit but apparently brassicas are the best companion plants for onions but lettuce can work.
I coincidentally bought lettuce plugs and onion sets at the weekend!
Ah cheers. The onions and garlic went in in autumn so are reasonably well established (though possibly rotting away happily under the surface). There’s reasonable space and it’s Gem lettuce so may give it a go.
