My Rhubarb gets Fish, Blood and Bone in the spring and is then mulched with farmyard manure in the spring, then I give it another good layer of FYM in the late autumn, when I'm tidying up the garden for the winter.
About Christmas I put a forcing pot over it and then I get an early crop of tender pink stems - stop picking the rhubarb in May and let the plant bulk up again over the summer. I do this every year; it doesn't weaken the plant like traditional forcing where you lift the root and expose it to frost then move it to a warm dark place to force it.
I agree with Verdun about the beans - put them in the ground if you can - they need plenty of room and it's difficult to stake them properly in a pot as it'll get top-heavy.
