You could try spraying them with water as this is an age-old tip which is supposed to help setting. Don't blast the flowers off though - some hose attachments can be a bit too strong!
Surely if they are covered in flowers, you wont see the beans yet, give them time, I have never known of a row of runner beans
with no beans on it.
Have a couple on me.
This sometimes happens early in the season - don't worry, the insects will find them
I have a piccy of echinops just like yours David, the bees love it.
Some people would be horrified if I said I pick off the first flowers from the beans to allow the plant to strengthen.
Nor me Bekkie, I pick out the middles so that they make two strong shoots, then I pick off the bottom flowers, so mine havent done much.
I still have some in the freezer from last year, we had a bumper crop,
I just use my finger. I've been pollenating my courgettes and pumpkins, but they're quite easy because they're big. Otherwise a slim brush, like and old make-brush.
The pollen virtually jumps on to anything that goes near it, and the females tend to be moist, so the pollen just goes on very easily. They are freakily like us in that respect.
Winnecat, if you need to attract bees ,try planting phacelia near them, they grow easy and are a great green manure to dig in with the beans after your done and bees just love them,
