Vegetable Gardens 4 U and Sunshine Landscapes uses only organic material in our vegetable gardens, so that your yield is great tasting and healthy! Organic matter is used in the garden and landscape for many reasons. It helps all poor soils, whether they are too sandy or made of too much clay. In addition, organic matter improves soil by stimulating or feeding the life of the soil. It provides nutrients to bacteria, fungi, earthworms, and other organisms in the soil, which in turn recycle the nutrients into forms that are readily avail-able for plants to absorb through their roots. Organic matter also helps to prevent soil and wind erosion, and prevents caking, cracking, and water run-off that occurs when clay soil dries out.
