Hi All - Years ago I read somewhere that overwintering onion increased the risk of onion fly, so since them have never bothered to grow them as I try to use no sprays or chemicals.
What has everyones experience of this been?
Having said that I usually grow Jet Set and another long keeper (who's name eludes me at present), and find that my demand in the kitchen for onions tails off as the weather improves, so I usually last out with some shallots as well. And if I am desperate and spring onions or chives won't do I just pull a couple of half grown onions and use those
Interested to hear what others have found
