After umpteen attempts.
Same with Savoy cabbage.
I am wondering if it's too late now for them to produce.

Mine were looking very sad after I left them way too long in seedling

more healthy compost, and they're coming on a treat. Still in the
greenhouse at the moment. Nowhere near ready to go into the ground.
