Growing Onion

I planted white onions seedlings (variety unknown) in mid-June with the usual expectation that they would be ready for harvest in early December; when the tops usually start to dry out. This year about 50% of the plants have started to produce flower buds in early November. I suspect that if I allow them to flower; the quality and storage-life of the onions will be reduced. Should I harvest them before the first flowers blossom? Regards Bob.

Onions are biennial, that is they grow and die down in he first year then regrow and flower/seed in the second year. If seedlings of biennials are stressed in the punnets before they are planted or if the variety is not suitable for planting at the time of the year the plants may be triggered to flower and set seed. If you leave them they will increase like daffodil bulbs.
