The Effects of Laundry Detergent on Bean Plant Growth

Green Bean Growing Requirements

• There are two primary types of beans, bush and pole beans. Bush beans are self-supporting and do not climb or trail. Pole or runner beans require support. Sturdy poles, the garden fence or a trellis will provide adequate support. Traditionally beans are grown with corn so that the corn stalk can support the bean plant. Both types of beans require fast-draining soil. Water around the roots of the plant and allow the soil to dry between waterings. Excess water will cause dropping blossoms and root rot.

Grey-water Recycling

• Grey water is household waste water that does not contain sewage. Recycling grey water can greatly reduce the household consumption of potable water. However, some cleaning products contain corrosive chemicals and salts that are detrimental to plant health, especially in garden soil that is already alkaline. Unless the laundry compounds are totally organic, the toxic chemicals will damage your green-bean crop, or may kill the plants. Cleaning products that contain phosphates can also damage plants. Phosphates encourage excess foliar growth, and few bean pods will develop to maturity. If you use recycled water, flush the soil with rain water or other fresh water to prevent salt buildup.

Choose Organic Products

• Select only organic laundry, dish-washing or personal-grooming products. These products are made with natural ingredients that will not harm your family or damage your plants. Avoid products with artificial "whiteners" or "brighteners." Do not use products that contain bleach or any form of chlorine.
