Growing Beans - climbing, also Pole beans, Runner beans, Scarlet Runners

03 May 17 Rosemary Jorgensen (New Zealand - temperate climate): I also have grown trouble free Scarlet runner beans for years. Last year I had no beans at all. This year I had enough to feed us but none to give away. The culprit is the green vegetable bug or shield beetle. They suck and forming beans dry and then they do not develop. This last season, I examined them every day and squashed beetles. I still was scarcely winning the battle. It is hard to spray with anything because the plants are always in flower and we are eating them every day. I am also inundated with white fly. I sometimes have success water blasting them off, but they are far too persistent on the beans.

04 May 17 Sean (Australia - sub-tropical climate): Climbing beans, such as Scarlet Runner, often don't set if you have a run of hot weather. White fly are attracted to bright colours like yellow. Get a piece of bright yellow card or plastic sheet and smear it with petroleum jelly. Tie or nail this to a stake near your beans. The white fly will be attracted to the yellow and will stick to the greasy petroleum jelly.
