Previously with my runner beans I had been wondering why the flowers weren't setting, I thought they were being eaten. One of the suggestions was that the dry weather didn't suit runner beans who like a moist atmosphere to aid pollination.

We haven't had rain here for months, so I started spraying the runner bean foliage each day as well as keeping the roots wet.

And hey presto! runner beans have set! A moist atmosphere helps the flowers pollinate and the runner beans have been setting.
So why are my climbing beans Mrs Fortunes being eaten?
I found out today...
It wasn't a slug.
