Fertilizer and Soil Amendment: Made from a combination of our Pure Worm Castings mixed with added Worm Egg Material to enhance the microbial activity of your soil while providing aeration, improving drainage, and adding nutrients. High Quality Fertilizer: Pure Worm Castings aerate the soil and improve drainage while adding nutrients and boosting microorganisms in the soil to grow better, healthier roots for fuller, and more fruitful plants. Promotes Living Soil: Worm egg material is the cocoons the worms lay, and tiny balls of soil mixed with bits of bedding not eaten by our worms, which helps to increase the microbial activity in soil - Some debris including small rocks may make it through the sifting process. A Chance for Worms: Worm eggs may hatch in soil, adapt, and begin to help improve soil quality - Worm tunnels bring in oxygen, drain water, and create space for plant roots, and live worms will produce more castings. Simple Packaging: Ships in a black-and-white printed bag with the same great product inside.
