Runner beans - masses of flowers, only ONE bean.
I have 3 White Lady runner bean plants in a big pot on my patio. It is my first attempt at growing them. They look really healthy and have smothered the 6' wigwam with masses of leaves and flowers. 9 days ago I spotted my first miniscule bean, and felt really proud! But since then, absolutely nothing - just dead flowers on the ground. Bees don't seem to be visiting, even though I have planted some sweet peas with the runners and there are single dahlias and roses nearby. Any suggestions?
