The Readi-SOIL Seed Starter is a naturally perfect blend of our own, site-managed worm castings combined with distinctly homorganic deep woods peat moss, resulting in the perfect planting soil. Our worms are fed a consistent diet of non-GMO corn silage, a high energy food source for cattle, goats and sheep and grown on site. The corn silage itself benefits from being fertilized with our own worm castings. With Readi-SOIL, the gardener can enjoy beautiful garden plants, helping create the vegetable garden of your dreams without potentially harmful chemicals, or the need to add any other supplements.
