Hi, I had a successful year growing my onions from seed last year. i sotarted them off in early march, and they grew well. However they were not particularly large onions. has anyone got any hints or tips in how to grow larger onions?


  • I think people usually start onion seed off earlier than that in the Green House.Sowed some Ailsa Craig myself at end of April. Some grew big a lot small.

    What fertilizer did you use?

    Kelsae or  Robinsons Mammoth are the ones to grow if you want big onions. exhibitors will have already sown, the shortest day is the traditional time, but I sow early February (in a frost free greenhouse) and got big onions. You can prepare the onion bed over the winter. Big onions like a lot of food, and no competition from weeds.

    You don't stop doing new things because you get old, you get old because you stop doing new things. <3
