Hardly worth it's own thread, but thanks for the offer anyway. I realise that a 3lb onion is a fairly modest target (the UK record is just short of 19lb), but I would like to achieve it for personal satisfaction. That's why I will have to say no to the £2.50 offer, because the whole point is that I have to grow the onion from seed to count. I have no specialist equipment and don't buy any specialist feed apart from digging in a bit of Growmore a month before planting out. If he has any tips for home made plant food I would be interested to hear them.
