Brassicas after beans

[Elderflower]

I`ve got my winter greens, kale and psb, in pots to go in after the broad beans are over.
However, they`re doing very well and are about six inches tall while the broad beans are only just nearly ready for picking. It`ll be ages before the bed`s empty!
What should I do?
I`ve got an empty bed that last year`s winter/spring greens came out of that I was saving for the leeks but would I be better putting them into bigger pots and letting them grow on?

Any thoughts?

I think I would try and persuade the brassicas to hold on a bit longer. The beans will be over relatively quickly. The best kale I ever grew was someone else's overgrown potbound throw-out that I chucked in expecting it to die. I'm no expert, though...

I'd hang on a bit but it the plants look to be suffering pot them into larger pots.

Thanks folks - I`ll get some next-size pots ready.
