Green beans are tender, warm-season vegetables that are popular for home gardens. There are two basic types of green beans. Bush beans grow upright without support, while pole beans climb supports to stay upright. These cold-sensitive vegetables are planted after all danger of spring frost is gone. Using a plant pot to grow green beans allows the gardener to take advantage of unused gardening space. It also lets gardeners with limited space to grow a traditional vegetable garden plant in a nontraditional way.
Drill at least four holes 1/4 inch in diameter in the bottom of a 5-gallon plant pot if it does not have any drainage. Wash the container with soapy water. Rinse with one part bleach and nine parts water to eliminate any hiding pests and plant disease.
Mix together one part sand, two parts potting soil and two parts peat moss. Fill the bottom of the plant pot with 1/2 inch of small stones, gravel or broken clay-pot pieces.
Fill the plant pot with the soil mixture, leaving 2 inches of space below the rim. Mix 1 cup of 5-10-5 slow-release fertilizer into the soil.
Tap the sides of the plant pot to settle the soil without compacting it. Create four to six holes 1-inch deep evenly spaced around the edges with your fingers. Drop a green bean seed in each hole and cover with soil. Sprinkle the plant pot with water until the soil is wet.
Tie three 6-foot sticks together near the top to form a tepee. Place the stick tepee in the green bean container. Train the green bean plants up the poles once the plants start to grow. Move the green bean plant pot to a sunny location with protection from the wind. Pour water in the top of the container, allowing it to run through the bottom of the plant pot. Water once a week after the green beans have sprouted. Do not sprinkle the leaves since this may spread plant disease.
