They are planted out in my veg patch. I planted them in Feb.Why does this happen? 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago Onions flower early if they get a cold spell in early spring or it the weather is dry, both of which happened. February is early for sets and runs a risk of bolting. Take off the flowers and use the onions as soon as you can. They will not store.
