What to do with these August-sown onions?

[Vetivert]

I have a tray of Senshyu overwintering onions which are in need of transplanting, but I'm unsure of what to do next. Do I transplant individually into cells, or straight into a bed outside? Cheers

That's excellent, thanks very much Tee Gee!

That's great clear advice, Tee Gee. I have to add though that for me it would be a great luxury and rather expensive in compost to plant on each seedling into a 3" pot.

I've pricked mine out with one, two or three to a 24 module tray. So some will be singly planted and some two or three in a clump, ie. multisown. As long as they're planted out before they exhaust the compost, it seems to work fine.
