If you’re considering entering a heaviest onion competition next year, you should be thinking about sowing some seed right now. You must though make sure that you have the correct sort of seed to start with, the saying ‘you cant make a silk purse from a sows ear’ is perfectly true in this context. The seed has to have the in built capacity to grow to a large size, after that it depends exactly on how you grow it and how well you look after it. My blanch leeks have been growing away now for over five weeks and it’s amazing how fast they develop from bulbils given the ideal conditions to grow under.
