growing pole beans on my porch
They're doing very well, but are now to the top of the porch roof. Do we prune them or just let them go?

Do you have support poles for them to wind around?
They should be about 6 ft tall, the vines can be encouraged to stay on the poles.
I personally would let them grow and not pinch back, but your certainly can if they just are to tall.
Here is a couple of great links.
