Dig the soil in your planting bed with a spade or pitchfork. Amend and enrich the soil by spreading a 1- to 2-inch layer of organic matter, such as peat moss, chicken manure or compost. Mix the organic matter with the garden soil.
Plant the bean seeds, one at a time, by pressing each seed into the soil, 1 inch deep. Plant the seeds 2 to 4 inches apart in double parallel rows, 12 to 18 inches apart, leaving 36 inches between each double row. Water the seeds daily until they sprout.
Thin the seedlings when they are 3 to 4 inches tall, leaving 4 to 6 inches between seedlings. Drive bamboo stakes into the ground around pole beans to support the vines as they grow.
Pick green beans when they are young and tender. Let dried beans mature on the plant until the bean pods turn brown and the beans inside are hard to the touch. Dry the beans at room temperature for two weeks, then store them in airtight containers.
