Worm Castings

Worm Castings are worm "poop". Worms ingest decaying organic material, grind it up very finely, extracting nutrients from the bacteria growing on the material, and excrete the result as "casts" or "castings".

While it is in their guts, worms inoculate the organic material with high concentrations of beneficial soil bacteria, two kinds of plant growth hormones, and significant amounts of humic acids. Humic acids are extremely beneficial to plants, storing nutirents in forms that plant roots can easily absorb.

Worm Castings also contain substances that help soil to "aggregate" or form clumps in healthy ways, making it easier for plant roots to penetrate the soil.

Worm Castings help plants resist diseases. Cornell University has published research showing that Worm Castings and Vermicompost help plants resist diseases. This video on Youtube shows how.


Using Worm Castings

For new vegetable beds: or to rejuvenate an old bed, mix about 40 lbs per 100 square feet of bed into the surface of the soil.

For Seed Starts: add 10 to 15% worm castings to your potting mix.

Transplanting plants: Add some castings to the soil as you transplant. Small plants will benefit from a tablespoon; larger plants could use 1/2 cup or a full cup.

Feeding: Sprinkle castings on the surface of the soil a month or so after transplanting or germination.



Between 60 and 80% of everything we send to landfills is compostable.
When this material decays, it produces methane - a greenhouse gas.
You can help change this. Join the Composting Circle.
