Worm castings, also known as vermicompost, are a valuable organic fertilizer and soil amendment that can greatly benefit gardens, farms, indoor plants, and even aquariums. These nutrient-rich castings are produced by earthworms as they digest organic matter, resulting in a highly concentrated and beneficial product for plant growth.
