Grew climbing, runner and dwarf green beans last year, with great success. This year, (in a different bed) lots of problems. The dwarf beans were extremely thin, some bobbly and others almost dessicated. The runner and climbers look okay, though some have gone a bit purply, but many are stringy to the point of being inedible. Today I harvested some, used a potato peeler to peel the strings off both seams, cooked and put them in the blender for a soup, as a last resort. Even so I still had to sieve the soup (and clear out the drain afterwards) I've watered them every evening since this drought started, so I know it's not lack of water. Perhaps they just don't like so much sun? Any views?
