Worm Castings & Soil Mixes
Only a few left!
Back2TheDirt's premium worm castings are a perfect soil amendment and natural fertilizer for farmers, gardeners, and indoor plant enthusiasts. Help support both your plants, soil, and community! Our worms are fed local food and paper waste collected from our Cincinnati compost program. Castings are sieved with 1/12" mesh. They have a neutral pH and no odor. We price our castings by gallon, since moisture can greatly affect weight, you know exactly what you are getting (1 gallon=~4 lbs). Apply at a rate of 20% castings by volume for potting soil mixes or 5-10 gallons of castings per 100 square feet of garden space or 2 gallons per 100 square foot of lawn.
Worm castings contain:
Beneficial soil microbes • Plant nutrients and minerals • Natural plant-growth hormones
Castings have been shown to:
Increase root growth and plant biomass • Speed up germination of seeds & increase seedling
growth • Reduce transplant shock • Reduce pests • Suppress plant diseases • Increase soil porosity and aeration • Decrease water loss and nutrient leaching • Increase cation exchange capacity • Buffer soil pH

It mixed in well with my raised garden container and I believe it will help fertilize it for a better crop next year.
Potting Soil Mixes
Island Soil Mix
Our potting soil mixes are made to keep both your plant and the planet happy!
Our "Island Mix" contains a blend of our premium worm castings, coconut coir, pumice, perlite, and shredded pine bark―with a biochar and kelp fertilizer boost. Our blends are made to keep your plant roots aerated, all while providing the essential nutrients your plants need to thrive.
Coconut Coir- Provides structure for the roots. Good water retention and low bulk density. 100% Renewable.
Worm Castings-Provides plant nutrients, minerals, and growth hormones. Microbially rich. Improves soil aeration and buffers pH. 100% Renewable.
Pumice- Improves soil aeration and drainage. Retains excess moisture. Pumice does not break down, and since it is heavier than perlite, it will not float to the top of the soil. Pumice is mined from New Mexico.
Perlite- Improves soil aeration and drainage. Perlite will not break down over time. Perlite is a mined product.
Shredded Pine Bark-Improves drainage and aeration. 100% Renewable.
Kelp-Provides trace minerals and vitamins. 100% Renewable.
Biochar-Prevents water and nutrients from leaching, releasing them when your plants need them most. Biochar does not break down and contributes to soil structure. 100% Renewable.
*For local pickup/drop-off a $7 in store credit will be offered for each bucket returned
I really liked this soil mix. I liked that it was in a papersack and the potting soil was lightweight and not clumped like many other bagged potting soil. My plants like it too. A little goes a long way.
Mixed in with my new red raspberry plants and seems rich and full of nutrients. Will have to see how they progress next spring.
