I am desolate - I have been growing runner beans in large pots for many years with no bother. Now, though, many flowers have dropped from the unusually long stems and it looks as if I may not get any beans at all. What has happened?
I think it maybe the heat, you'd be surprises how quickly plants dry out and then they get stressed, don't fruit and have spindly stems. Not your fault, we're not used to this kind of heat I'm afraid they don't sound as though they're salvagable.
Give them a good soak. dont feed. If it cools off a bit then they will carry on trying to flower and form seed pods.
Thanks, folks. Yes, I think I should have taken more care - like spraying and even fleecing. I suppose that, because I'd had no bother for twelve years (!), I thought they'd always come good. Thanks to my old man giving a hand, they've been really well watered, sometimes twice a day. Ah well.....If we have a heatwave next year, I'll be ready. But meanwhile, NO BEANS... Boo Hoo
Thanks for your input, Verdun!
My beans in pots are prolific and earlier than those sown at same time in ground. The "secret" is watering with hose every day. Fine spraying with hose under the flowers is supposed to help setting. Start now and plants will flower probably towards the top of plant.
