We are devoted to a beneficial relationship with our customers, our employees, our vendors, and any others with whom we have contact.

What are Worm Castings?

As worms digest food, they leave their castings behind in the bedding or soil where they live. Castings (or vermicompost) are worm excrement. The vermicompost is made up of live biological organisms, including fungi, actinomycetes, beneficial bacteria, pseudomonads, plant growth regulators, yeasts, molds, trace elements and Nitrogen, Phosphorus and Potassium (N-P-K). Castings actually contain a perfect mix of nutritional needs.

“Everything I plant thrives, including things I have had problems growing in the past. I use lots of your worm castings in the soil a couple times a year and it makes a big difference. I also make worm casting tea a few times a year and pour it over the entire garden. Thanks for the excellent product.”
