This year I am only planning on growing a few onions and have opted for centurion sets, these were planted out on 25th April.
02/05/2015: After getting tempted at the garden centre I have also sown a small seed tray of shallot seeds, yes I know its too late etc. but I'm hoping its still worth a try.
04/05/2015: A slightly late row of "North Holland Blood Red Redmate" onions were sown in the seed bed between the arrowroot and new artichoke bed. This variety can either be taken as spring onions or allowed to form bulbs and then used as a salad onion.
