    I sowed my onion and shallot seed today. I'm having another go at giant onions as I have seed from last year of Kelsae and Ailsae. Also growing Mammoth Red plus a few normal sized varieties:
    Red Brunswick
    Golden Bear
    Shallot Zebrune (Banana shallot)

      I want to try growing onions again this year but I don't get much success with sets. I've never tried them from seeds, Is that the best way to grow them ? I just want ordinary ones though.

        It is best from seed @Michael Hewett as they don't bolt so readily like sets do. They do need an early start, I sowed Golden Bear last year at the end of February which was a bit late, it's a nice normal variety that stores well.

          For me seed grown onions are more reliable than sets which I also find tend to bolt.
          I just use those cell trays with a pinch of seed in each cell.
          Sown in a greenhouse in early February, I don't have lights, they can stay in the trays until planting out in early April.
          I plant them without breaking up each clump of plants.
          Get medium sized onions, I don't really need big ones.

            I have been itching to just sow some seed for a while - starting off seed trays means spring is on the way. I have managed to resist so far.....but have just learnt that onion seeds can be sown now!!!! So, it'll be onions this year then, off to garden centre this afternoon :-)

                I sow indoors at end of February for my onions, then when germinated they go into the unheated greenhouse. I don't grow large/exhibition onions though, I would have started them now if so. They do get fleeced for a few weeks when planted out.

                This year I have santero F1 for my main crop keeping onions, then Walla walla as a sweet onion, white Lisbon for spring onions and also zebrune shallot. All module multi sown

                  Walla Walla, not heard of that, have you grown it before, sweet onions are something I like, but not grown any for a while.

                      About half of my varieties have germinated and are now under grow lamps. That's the easy bit done.

                        I've noticed D.T. Brown are now selling Kelsae seed, now produced in the UK, but at a much higher price than before the Italian thunderstorm that nearly wiped out all the seed plants.

                          They also sell Kelsae plants, in case you haven't got your seeds going by now. I recall someone on here said they tried them once and they were pretty tiny plants that were delivered - could have been @Scrungee ?

                          I tried them once John and indeed they were on the small size. I won't be growing them here in London (onion white rot). I will grow them in my garden in Lincolnshire but not for another year or two when I retire there.

                            That's all my onions sown now, 30 multisown cells of santero and hytec, 10 walla walla, 10 white lisbon and 10 zebrune shallot. Assuming i get good germination after thinning should have 350 onions in total.
