Sprouts "Bosworth F1"

[Headfry]

They are not growing very tall- at all, maybe about 20" tall now????
anyone else growing these - how tall are yours?
What have I done wrong. They started out so well, lovely strong growth.
Any ideas please.

I think I'm growing them and I think that mine are the same size. Sorry to be a bit vague, but all of my brassicas are well mixed up, whoops.

I have Bosworth and Bedford Fillbasket.They are mixed up as well-one has darker foliage but don't know which one is which.Mine are about the same height as yours.
