Vital Earth's high-quality organic potting soil is the perfect medium in which you grow all your fruits and vegetables. With sphagnum peat moss, which increases the holding capacity of air and water and decomposes very slowly, your plants are sure to be happy and healthy from seeding to harvest. In addition to sphagnum peat moss, this organic potting soil also contains an earthworm bedding, which helps nutrient and water absorption. As if it weren't enough, this organic potting soil also contains specially formulated Vital Earth's® Organic Compost OMRI, which provides fertility to soil as well as suppressing disease. Humus helps your soil retain moisture by increasing its microporosity.
