I have some leeks in a litter tray (a la DD) but as I am giving up my lotty they never made it into the ground.

I have a new raised bed in my garden... if I planted a few in there would they grow on any further? I wouldn't expect mammoth leeks but would they do anything?

They are pencil thickness at the moment.

Go for it.

At worst you'll get baby leeks that'd cost an arm and a leg in the shops.

Sounds good to me DD.... Baby leeks are better than no leeks 

I'll let you know how they get on.

Aunty kept leeks over winter and posted a pic of the monsters she had by spring. Once onions are established, they don't mind cool weather.
