Hi Charles
I sowed onion seed on 14th February in modules and planted out small seedlings on 21st March under a double layer of fleece. Almost all have disappeared! We have had a very wet March in Devon (not so sunny Exmouth!) and I guess that the fleece, resting on the seedlings, has been permanently wet. I wonder if this has been the problem. Is it likely to be just the difficult start to the season?
I will try some sets and experiment with resowing seed. Is this best done in modules as before?
Best wishes
John
