Worm Castings Organic Fertilizer: Our worms are raised in worm beds that are decades old and work all layers of the compost, not just the top few inches, creating a wholly better compost. The worm casting mix is full of nutrients and aerated by the earthworm colony, providing the best possible growing base for plants. Black Gold Worm Castings: Using live earthworm castings for gardening and plant growing purposes can benefit any garden or farm soil. The food scraps and waste the worms consume in the compost bin gets digested and transformed into some of the most nutritious earth material that lawns and gardens could grow in: worm castings! Organic Worm Castings: The worm castings produced by our worms are 7 times richer in phosphates, 5 times richer in nitrogen, and 11 times richer in potash than average lawn soil. The ample supply of nutrients provided by each worm composter helps your garden to grow healthier plants and this valuable substance is all a result of your trash! Composting Worms Help the Earth: By feeding food scraps to compost worms instead of throwing them away, we all help to recycle nutrients and keep less trash in landfills. Using worm castings also reduces the need for harmful earth-destroying chemicals, instead relying on safe, organic compost production.
