In the Spring, plant beans after all danger of frost has passed. In the Fall, plant beans 10 to 12 weeks before the first expected frost. For large plots, use ¼ to ½ pound of seed for each 100 feet of row of green beans. Plant pole beans in hills about 3 feet apart in the row. Space the rows about 3-4 feet apart. Place a 6-8-foot stake in the center of each hill. Plant 3-4 seeds around the stake about 1 inch deep in the soil. Planting in moist soil is best for seeds to germinate and emerge quickly.
