These beneficial insects are safe and separately ordered can cost hundreds of dollars and they all come for FREE inside your bag of Colorado Worm Company Castings. Most companies cannot guarantee this because they repackage truckloads of worm castings that look like "Pure Castings" because the worm bedding is dark black sedge reed peat that looks like castings. Colorado Worm Company uses finished Farm Made Compost as their bedding source. This is the absolute best way to do this as taught by ClackamasCoot and many others.

👨‍🌾 Crafted with care on a family horse farm in Western Colorado, each batch of COWOCO vermicompost is a testament to our commitment to organic, high-quality soil amendments. We feed our privileged worms a rich diet of bio-dynamic, fully finished compost, native soils, and glacial rock dust. 🌾

🛡️ Guaranteed Performance: We're so confident in our castings that if they don't outperform your expectations, we'll offer a replacement bag or a full refund. Expect your castings to arrive moist, rich, and teeming with life, or we make it right!

1 Cubic Foot = Approximately 40 lbs
1/2 Cubic Foot = Approximately 20 lbs
2 Gallon Bag = Approximately 10 lbs
1 Cubic Yard = Approximately 1000 lbs

Application methods and rates:

🌼 Top-dress your flowerpots or raised beds with a generous two-inch layer every two weeks to one month during both veg and flower stages. For an extra phosphorus boost, aerate water and add our castings at a rate of 1:10 to water, brew for no more than 24 hours, and apply directly to the root zone for immediate results.

🌍 Eco-Friendly Production: Our operation boasts a minimal carbon footprint, utilizing only a modest tractor while maintaining a closed-loop system with our hardworking worms. 🚜
