Get creative when you lack garden space. Even if you do not have land for a garden, you can plant many of the same vegetables in 5-gallon buckets that you would plant in the soil. Pole beans are well-suited for container-growing because they grow vertically up a support system. Place your buckets in a sunny location where you can build the twine support.
Drill three or four holes in one side of the bucket (spaced 2 inches apart) and tie a 5-foot-long piece of twine into each hole. Stretch the twine overhead from the bucket to an overhead, where you can attach the twine to create climbing supports for the pole beans.
Fill the bucket to the top with potting soil.
Plant the pole bean seeds approximately 3 inches away from the edge of the bucket just below the twine supports. Space the beans 2 inches apart, placing as many bean seeds as you can fit into this side of the bucket.
Push the bean seeds beneath the potting soil approximately 1 inch and firm the potting soil above the seeds.
Provide enough water to saturate the potting soil immediately after planting the seeds. Keep the potting soil evenly moist without allowing it to dry out between watering.
Fertilize the pole beans after one month by mixing an all-purpose fertilizer with water according to package recommendations for the size of your container. Pour the fertilizer around the bean seedlings. Fertilize the beans once per month during the entire growing season.
Train the pole beans to climb the twine if they need encouragement. Loosely tie the vines to the twine, if necessary.
Harvest the pole beans when they are tender and approximately 4 inches long. Continue to pick the beans daily to encourage the plants to continue producing beans.
