Whether a young gardener plants one bean seed to learn about how a seed grows or an experienced gardener plants several rows of bean seeds in a garden, the process is basically the same. Beans need warm temperatures to germinate. When a gardener plants a bean seed in the soil and gives it water, it will germinate and grow into a small bean plant. With continued care, the bean plant will produce a small harvest of beans within several months.
Fill the small container with potting soil if you will be planting the bean in a container. Prepare an outdoor growing area with the garden spade if you will be planting the bean outdoors. Work the soil of the outdoor growing area down to a depth of approximately 6 inches with the garden spade and add 1 inch of compost to the top of the soil. Work the compost into the soil with the spade.
Make an indentation in the soil of the container or the growing area with your finger. Plant a bean seed horizontally into the indentation and cover the bean seed with 1 inch of soil. If you are planting more than one bean seed in an outdoor growing area, space bush beans 4 inches apart in rows 2 feet apart and space pole beans 6 inches apart in rows 3 feet apart.
Provide a stake or a pole to support pole beans if you planted a pole bean variety.
Water the bean seed(s) immediately after planting. Provide at approximately 1 inch of water each week. Remove any weed growth that grows among the bean plants to ensure the beans receive adequate nutrients from the soil.
Harvest beans when they are firm and about 4 to 6 inches long. Harvest only when the beans and plants are dry because picking from wet plants may introduce a bacterial infection that would damage the bean plants.
