Broadbeans- probably a stupid question...

I've just harvested all my broadbeans, will the plants flower again or do I pull them up now?
The plants look healthy and are still growing!  I haven't pinched the tips out or anything... But not sure if they will give me another harvest or not 


Thanks in advance 

You can cut them down and let them re-grow, which may give you a much reduced secondary crop later in the season. I tried it myself a few years ago and got a small crop from them.
Depends if you need the area of ground for another crop really. If you have nothing else to go in, then you might as well try it
