Plant pole beans if you want an abundant bean crop that takes up little space in the garden. Since pole beans grow vertically as vines, they do not require the amount of garden area that bush beans require. Pole beans usually climb up their support poles with little aid, but as the plants become full with ripening pods it may be necessary to tie them in place so their weight doesn't pull them down. Shelling beans are more likely to need tying. Unlike green beans, they stay on the vine longer until they are fully mature.
Guide young bean vines onto the pole by wrapping the tip of the vine clockwise around it. The vine should start climbing the pole on its own thereafter.
Examine the vines after the pods are beginning to ripen for areas where the bean plant is not tightly wound or is pulling away from the pole. Also look for areas on the plant that are full of blossoms or beans, as these parts are more likely to require tying later on.
Cut a 10-inch length of garden twine. Wrap the twine around the pole and cross the ends over each other. After crossing the ends, pass them around the bean vine. Tie loosely. The tie should resemble a figure eight with the cross between the vine and pole.
Tie the bean above the flower clusters and pods. If the plant sags under its weight, the tie will not be able to strip off the flowers and pods if it is tied above them.
