Choose poles that are 7 or 8 feet tall for pole beans or indiscriminate peas. Plants can grow to be 6 feet tall, and the bottom 2 feet of your pole will be underground.
Install your poles once the ground is thawed, before you plant your beans. Wear gardening gloves to avoid getting splinters or scraping your hands. Grasp the pole firmly and push it into the ground wherever you plan to plant your beans or peas. Push the pole about 2 feet into the dirt to make sure it's sturdy enough to support your vines once heavy pea pods start to grow.
Plant your peas or beans at the base of the pole. Once the plants are a few inches tall, begin winding the vines around the pole. If the vines do not stay in place, or don't climb on their own, use soft string or pantyhose to train the vines to the pole. Tie loose loops to keep the vine in place, being careful not to squish the delicate plants.
