How to Build a Trellis for Beans

Overview

Gardeners can build a trellis for beans to keep the pole beans off the ground where moisture may cause them to rot. The trellis can be a grid or netting of wire, twine or synthetic material like plastic or nylon. The growing vines of pole beans will wrap around and grow up a vertical support of a trellis in a clockwise fashion, following the sun from east to west. Build the trellis for the pole beans before planting to avoid damaging tender roots.

Step 1

Pound a few stakes 12 to 18 inches into the ground. The stakes can be metal, like those predrilled or hooked and used for fencing, or 2-inch by 2-inch wood stakes. Pound the stakes 5 to 10 feet apart in each row.

Step 2

Secure the end of garden netting to the first stake in the row. With metal fence stakes, the garden netting can be secured by wrapping a vertical strand of the netting around the protruding hooks. Wire or twine can also be used to tie the netting to the stake. With wood stakes, the netting can be nailed or stapled in place. If you're using wire and twine instead of garden netting, connect a strip of 10 to 12 gauge wire to reach from the top of the first stake to the top of the second stake. Connect a second strip of wire about 6 inches up from the bottom of the first stake and connect it to the bottom of the second stake. The two horizontal strips of wire create the framework of the trellis grid.

Step 3

Unroll the netting to reach the second stake and secure the netting to the stake to finish that section of trellis for the beans. If you're using wire and twine, tie the twine on the top horizontal wire about 6 inches from the first stake. Let the twine drop down to the lower horizontal wire where the twine should be tied. Continue adding vertical strips of twine at about 12-inch intervals across the wire framework. The planted pole beans do not have to be directly under a vertical twine support. The beans will seek out the best way to grow upward.

Tips and Warnings

  • In windy areas, additional horizontal strips of either wire or twine should be added at 6- to 12-inch intervals between stakes for added stability. Wrap the vertical twine around each horizontal support one or two times to increase tension and hold the crossed lines together.

Things You'll Need

  • Stakes (6 to 8 feet long)
