Choose a planting site in full sun. Bush beans require well-draining soil. The plants prefer a soil pH of 6.0 to 6.8.
Work aged manure into the soil a week or two before planting. Add the manure to the soil at a ratio of 50 percent manure with 50 percent garden soil. The soil should feel crumbly and rich to the touch.
Plant the beans when the soil temperature is 65 to 75 degrees Fahrenheit to help ensure germination. Dig a 1-inch-deep hole with a garden trowel. Drop the bean into the hole. Cover the bean with soil. Space each bean three to four inches apart. Locate the bean rows so they sit 18 to 24 inches apart.
Water the newly planted beans. Apply a 2-inch layer of mulch across the soil's surface to help keep it dry. Keep the beans evenly moist throughout growth.
Harvest the beans when the pods completely dry out and begin to split open. Take a bean from the dry pod and pinch it between your fingernails. If the bean does not dent, it is ready for harvest. Handpick the bean pods from the plant.
