The end result of Vermicomposting is Vermicast, which is what is left after the worms completely break down the material! The reason why Vermicompost is considered “black gold” is because it is packed full of water-soluble nutrients. When added to the soil that your plants are already rooted in, it acts as a nutrient-dense, organic fertilizer, as well as a soil conditioner. When your plants are exposed to water and vermicast, they are being given access to the best nutrients around. Vermicast is for anyone! It is used on farms in larger quantities and is also popular among gardeners and green thumbs alike, who are just looking to take the best possible care of their plants.
