Gardening supports can add a good deal of growing space to a small area. By growing vertically, plants produce a larger crop because more flowers are exposed and fruits and vegetables do not rot because they do not lie against the ground and are easier to pick. A bean tower provides these benefits to bean plants and makes growing them much more rewarding.

To build a bean tower you will need:

4 uprights: 2 x 2 x 96"
4 top crosspieces: 2 x 2 x 12"
4 bottom crosspieces: 2 x 2 x 48"
3 diagonal braces: 2 x 2" x 9', cut to fit
28 screws: #10 2ΒΌ"
Ball of string

The tower itself is easily moved in order to allow optimum placement in your garden. Three sides are covered by string, and beans are planted against these sides. The last side is open to allow you to reach in and pick the beans.

The four upright pieces, as well as the top and bottom crosspieces, can be made by ripping 2 x 4s. Make sure the crosspieces are their proper length, and drive nails partway into three top and three bottom pieces to hold the string. Make one side using two uprights and a top and bottom crosspiece. Put one screw through each end of the crosspieces into the uprights. Make another side the same way and put both upright on a flat surface. Fasten a top and bottom crosspiece to connect them, forming a three-sided structure. Attach the opposite crosspieces in the same manner.

Set the assembly squarely and drive a second screw through each joint to secure it. The diagonal braces are fastened onto three sides to add further strength. Wind the string around the nails in the crosspieces and your finished product will have string on three sides with the fourth side open. Position the tower in your garden, mulching the inside to keep weeds from growing inside it and plant the beans against the outside of the three sides.
