Scroggin, I plant a seed close to the roots of each sweetcorn plant when they are about 10-12 inches high, otherwise the beans will easily outgrow the corn. As the beans grow, they are trained to twine round one corn stem, then over to another etc, so they do not climb vertically as such - the bean stems are used to 'tie' the corn stems together. When there is enough support for the corn crop, I nip the tips of the beans off. There are usually beans available for harvesting well before any cobs are ready. After harvesting the cobs, if the beans are still cropping, I leave the whole shebang and cut down when everything dies in early winter. Any beans harvested are really a bonus as their primary purpose is to provide nitrogen for, and to support, the corn.
