Trellises for pole beans are necessary for a healthy and abundant crop. Additionally, they provide a vertical design element in your garden. When selecting trellises for beans, be creative. Consider the look and feel you want to achieve in your garden and how much money you want to spend. Options include easy-to-make pole tepees, living supports such as sunflowers and attractive, but expensive, iron or wood-crafted designs.
The most common and inexpensive method of trellising beans is to use "tepees" made out of poles. To do this, assemble three or more poles in a cone shape. Dig the bottoms of the poles into the dirt and secure them at the top with sturdy twine, wire, or nails. Poles can be bamboo stakes, 2-by-2 cedar cut to 6 or 8 feet long, metal rods, PVC piping, or, for an economical and rustic-looking option, fallen tree branches.
Living trellises are another traditional and economical option. Rows of corn make excellent trellises for beans. Sunflowers also make an attractive and sturdy trellis. Any very tall plant may function as a trellis, but those with sturdy and relatively bare stems work best.
Garden supply shops sell a wide variety of attractive trellises. They can be quite expensive, but this may be worthwhile if you intend to leave the trellis on display through the winter months, or if you do not want to build a trellis yourself.
