Worm Castings

Worm castings are an all-natural and organic source of nutrition for your soil. They are the safest and most effective alternative to fertilizer. Made using only the  highest quality organic material.

Organic worm castings are famous for repelling pests and helping plants grow and absorb nutrients under challenging conditions. Unlike chemically treated soil designed to support one harvest, worm castings provide healthy bacteria that enriches the soil, creating more sustainable fertilizer. 


The castings are produced in "wedges," where about 10,000 worms are fed a weekly dose of 1-2" of compost. As they feed on compost and more is added, they eat through the wedge and leave behind coveted castings (poop), which are harvested and offered for sale. All castings are boxed fresh daily to ensure you take home active microbes!


Available only in 8 qt and 1 qt bags.
