I grow runner beans every year in long deep troughs with good quality grow bag compost.  Had yearly success until now.  Plenty of flowers but it seems that something not visible to my naked eye is "eating" the bean as I am left with thye stem of what should be the bean?

No allotment and restricted on space hence the way of my "plot"

Lack of water? Them is heavy drinkers and last year was a lovely wet year.  This year here has been hot and dry - I've been taught to mist the flowers late in the evening in hot dry weather.  Have you had the pollinating crew (bees and others) visiting?

gallon upon gallon and have seen several bees around them - have about 4 beans growing but the rest which have lost their flowers - zilch - have plenty of flowers left though.

Must be something to do with your location!!  

Ours are doing brilliantly. Must have picked about 20lbs worth so far since the end of June.

PUP!

I just picked our first couple of pounds today. They are a bit late.  
The quality appears to be good and there are plenty of embryo beans on the plants
Possibly the wind hasn't helped and certainly we have not had as many bees about as in other years.  
I notice that our discovery apple crop is also a bit thin.

Rabbits! My beans were being eaten by them until I put up a smaller size netting around the perimeter of my plot. Now I am harvesting Runners and French
