I’m still trying to find an answer to this on the internet. In the meantime, I’ve been storing my potatoes in a lower kitchen cupboard, but I haven’t noticed if they’ve been lasting any longer.
Everything I’ve read says not to store onions and potatoes together. But that’s where the consensus ends. There is no agreement on why. Some articles say it’s because onions emit ethylene gas and potatoes are sensitive to ethylene gas. Other articles say potatoes emit ethylene gas and onions are sensitive to it. Still other articles say potatoes both emit ethylene gas and are sensitive to it. Other articles say potatoes should ideally be stored in high humidity, while at the same time saying a dry, well-ventilated place. It’s quite funny reading all about this on the internet.
I guess the takeaway is that potatoes and onions shouldn’t share the same airspace in a confined area. ie. same drawer. But what about say, the same tall pantry cabinet, just on a different shelf?
I still don’t know how close is too close.
