Mountain Gate Organics Earthworm Castings

We at Mountain Gate Organics are a small family owned business located in Rockingham, VA. We specialize in the making of organic fertilizer derived from earthworm castings. Our earthworms are fed an organic plant based diet to ensure pathogens are not transmitted from the host to the plants. We have a system that applies strong manufacturing principles to ensure both quality and consistency. Due to our production techniques and harvesting methods, we can provide pure organic fertilizer with no impurities such as undigested bedding materials, stones, straw and worm eggs. Our multi-screening process eliminates eggs without the need for heat or other sterilization process, which can kill beneficial bacterial and microbes.
