You need any sturdy pole (wooden or PVC pipe) to dig into ground with at least 6 feet above the ground. Attach an old bicycle wheel horizontally on the top of the pole (I got mine from the landfill). Plant your pole beans in the circle around the pole (about 4 feet in diameter). I put seeds (soaked overnight) every 2 inches and then thin them. When plants emerge and reaches some 6 inches I use any kind of twine or thin rope cut in peaces a little longer than double distance from the ground to the bicycle wheel. Then I tie one end of the twine to the staple what I stick into ground at the base of the plant (we just cut thicker wire in 1 foot peaces and bend it in the middle), go up to the wheel and then down to attach to another staple at the base of the next plant. You get nice airy tower when you are done. When the plants start growing help them from the beginning wrapping around the twine. Soon they will catch up and go up by themselves. Usually I move my pole to other spot every 2 years. Staples get rusty but who cares! If you use heavier synthetic twine you can reuse it next year too after washing it but it takes more time in the fall to pull vines from the twine. When you use some organic twine then just pull out staples, cut it at the top and straight to compost pile they go. Makes very attractive accent green blooming tower in the garden. Easy to harvest.
