Talkback: Knowing your onions
I have grown and successfully stored onions for about five years now, usually managing to grow enough to last up until the next years crop is ready for lifting. I always buy 'Setton' as sets to plant out in late winter/early spring and after lifting them in late summer, i leave them on my greenhouse staging for about a month. I make sure the greenhouse is well ventilated, but is still warmed by the late summer sun to dry the onions well. This i believe has been key to my success. I then store them in the house under the stairs in onion sacks haggled from a market stall.
