Research has shown that high-quality worm castings are among the most nutrient-rich natural soil amendments available. They consistently outperform many synthetic fertilizers in supporting long-term soil health, microbial activity, and plant growth. Learn more about the independent research supporting worm castings on our Research page.
Worm castings absorb and hold more water than equivalent amounts of other soils. They increase water-holding capacity by improving soil structure through beneficial microorganisms.
Worm castings help protect plants by surrounding seeds and roots with beneficial microbes that can reduce the risk of certain soil-borne infections.
Worm castings enrich the soil with microorganisms. Microbial activity in the castings is 10 to 20 times higher than in the soil and organic matter the worms ingest.
Supports improved crop yields by enhancing root growth and structure, increasing water-holding capacity, and enriching the soil with beneficial microorganisms.
Worm castings can be made into a tea, used as a top dressing, soil mix or tilled in.
We recommend the following:
Top dressing: 1/4 inch layer on potted plants.
Soil mix: Add 20% to your mix (1 to 5 ratio).
Tilled in: 1 cubic foot per 100 square feet.
This is an all-natural product. We process our castings using a 1/8-inch screen. A small amount of seeds or other matter may be present. A few worms may occasionally be included. Due to the natural water-retaining properties of worm castings, some moisture may be present at the time of packaging. This is normal because we pack and ship our worm castings as promptly as possible.
