Potatoes chitting, with the help of an onion?

[Nicos]

I am aware that potatoes and onions are companion plants but I read an article a while ago that if you place an onion amongst chitting potatoes they will bring on better chitting?

I bought some cooking potatoes the other day which I fancied growing but noticed they were sprayed in something to prevent chitting.
So I washed them thoroughly and have now placed them in to chit with an onion next to them to see if they will actually produce chits.
Obviously I won’t know if it’s the washing and/ or the onion helping them to chit, but I thought I’d try this as an experiment!

Has anyone else tried this?

Is that why my potatoes in the kitchen seem to sprout so regularly? Need to find another location for them or the onions...

Nothing ventured nothing gained Nicos, why don't you set a washed potato up as well just to see the difference, as for chitting I never bother doing that though with other than seed potatoes it makes sense to do so
