Hello Gerry, I am an oap and have just started to try to grow a few veges for myself. I brought 3 runner plants and put them in a grow bag. They were doing really well until a few days ago I notice that one plant completely died and the others look as though they are stricken with the same complaint – the leaves look as though they have been eaten away leaving just the skeleton – I’m so disappointed – can you help? I love runner beans but they are so expensive in the supermarket. Thank you, Katie.
