I have lovely broad beans that are bulking up nicely. However when I have picked a few to taste -yes I can never wait -the small beans seem to be a brownish colour...is this normal.? Will the mature bean be ok?
Brown beans are not normal. Mine are a bright green. Some will be white when mature although young beans will still be green. Are the beans that you are picking very small? I don't pick mine until I can feel the beans in the pod.
