Onions & beans

So I am aware that the onion family hurts the soil bacteria that forms a symbiosis with beans, but does anyone know the minimum safe distance?

Sounds like a good trial. If nobody answers maybe I can try it at school next semester.

never much thought about a problem between onions and beans here..but come to think about it i doubht if I put them near each other cause onions I believe prefer a more alkaline soil than beans?

if garlic has a similar effect on the microbes legumes use, 12 inches seems to be working. My wife had never heard of this advice and planted the garlic in the same beds as the peas and beans. Both of which are growing like mad and blooming already.

Huh, I'm surprised to hear this. My beans grow far better around onions (and other aromatic herbs, such as dill) than they do without them, due to the beneficial predators attracted by the aromatics. I haven't checked the soil microbe levels. I'm eager to hear what you find.

everything grows better with beans !
