Pole varieties are also planted in hills three feet apart in all directions. Sow six to eight seeds in each hill and thin to three to four strongest plants to a hill. Care Weeds are controlled easily in the seedling stage by shallow cultivation. Do not cultivate too deep because bean roots are close to the surface. Black plastic stops all weed growth and may hasten bean growth by warming the soil.
Beans are sensitive to both dry and wet conditions.
Too much or too little water can cause beans to drop their flower buds or pods. Keep the soil evenly moist. An inch of water per week is needed during the growing season. This will moisten the soil to a depth of six to 12 inches. Harvest Snap beans are harvested as immature pods before the seeds are well developed.
