Runner Beans

[Little Lou]

Many thanks for this tip, Mary. My own runner beans were all right, as this year I had to grow them in pots with trellis towers right next to the house, and I harvested them all very young. However, I did have exactly this problem with my climbing French beans ('Cobra') and wish I'd known this solution a couple of weeks ago! They are now resting peacefully in the bowels of the compost heap...
Never mind. I'll know what to do if this ever happens again, so thank you very much for passing this on.
