Runner beans are usually ready to harvest in July, when the pods reach about 20cm (8") long. Avoid leaving the beans on the plant for too long or they'll turn stringy. Ideally, you should pick beans every day or two to ensure optimum tenderness and remember, the more you pick, the more pods your plants will produce. | GrowVeg
