Hello Hyacinth ;D
I'd reckon if you seeded into shallow seed trays, that might account for the total failure cos they both put down long roots. I seed both into pots to avoid them being taken by slugs, but I need to pot them on a couple of times for that root growth before they're finally planted out. But I don't have an allotment, just my garden, and I don't grow many.
Might this be the reason?

oops sorry, was so excited to be legitimately talking to myself without fear of the men in white coats knocking at the door, I forgot to say Welcome!
