Green beans, also referred to as snap or string beans, are one of the most popular vegetables to eat and grow. These relatively maintenance-free plants can produce an abundant crop throughout the growing season, and the yield can be eaten fresh or preserved through freezing and canning. Beans, whether green, yellow or purple, grow either on bushes or vines, and come in a wide array of hybrids such as Blue Lake, Soleil and Beurre de Rocquencourt.
Rotate crop planting from season to season. Avoid planting beans in the same location as the previous year to deter any diseases that may have remained in the soil. It's also best to avoid planting seeds where potatoes, lettuce, tomatoes or cabbage were grown previously.
Pretreat soil, before planting, with an application of fertilizer, such as Natural Fertilizer 4-3-3, or place fertilizer directly into rows when sowing bean seeds. Beans respond best in soil with a pH level of 6.0 to 6.5. Have your soil tested to determine the pH level and amend the soil to achieve the proper level.
Plant seeds at least 1 inch to 1 1/2 inches deep and 2 inches apart, in rows that are spaced at least 2 to 3 feet apart. This gives the bean plants adequate air flow and also will allow you space to walk between rows when weeding, watering and harvesting.
Water bean plants at the base of the plant to deter the development of fungal diseases or blossom drop. Only during feedings should you water the plants to properly disperse granular fertilizers. Water at least once per week during dry spells, and do not allow soil to dry out completely.
Stagger planting times for continual production throughout the growing season. Plant a new row of beans every three weeks through August to maintain a constant crop.
Pick beans as soon as they are ready. Constant harvesting of ripe beans will encourage production of new beans on the plant.
