Yes, and no. Worms transform whatever they consume to a very different material. However, the food they start with plays an important role in the value and quality of the final product. At Black Diamond VermiCompost, dairy manure is "hot" composted prior to feeding to the worms. This stage kills pathogens and weed seeds and is closely monitored and adjusted to maintain optimum temperatures. The worms are fed this pre-treated food and thrive on the bacteria, fungi and other decomposers that are generated through the composting process. A few weeks later, vermicompost is harvested. The final product, Black Diamond VermiCompost, is a very mature and stable material, promoting soil health and vibrant, strong, productive plants and trees. It will not burn and is safe for the most sensitive plants. Lab results are impressive. The worms are doing their job! We do our part to keep them well fed, warm and moist in an environment as close to nature as possible.
