According to horticulturists at Cornell University, pole bean plants yield two to three times more than bush bean plants. They also claim that some gardeners find pole beans to be better-tasting. Whatever your reason for wanting to grow pole beans, it is important to keep in mind that beans are a warm-weather crop and should not be planted until soil temperatures reach 70 degrees F. Preparing the soil takes minimal effort and requires only a few common garden materials.
Choose a spot in the garden in which to grow your beans. They should receive full sun all day.
Dig 6 inches into the soil with a shovel, and pile up the soil you remove. Dispose of any rocks or other debris you may find, and yank out any roots.
Add a 3-inch layer of compost to the pile of soil you removed, and mix it together with a gardening fork. Add the amended soil back to the planting area, and level it well with the gardening fork or a rake.
Create small mounds of soil for each plant, spaced 3 feet apart. The seeds or plants will be planted in these mounds. If planting more than one row of pole beans, allow 3 to 4 feet between rows.
Drive a stake into the middle of each mound, and plant three to four bean seeds around it, or plant your seedling right next to it. For larger-scale pole bean gardens, drive a 10-foot-tall t-post into each end of the row. For long rows, there should be a t-post every 20 feet. Stretch wire between the posts, at the top and the bottom. Loosely tie one end of a piece of heavy string or twine around the base of each bean plant and the other end around the top wire.
