Earthworm Castings (gallon)

Worm castings, also called vermicast, worm humus, or worm manure, are a superior nutrient source for your plants.  They contain the nitrogen, phosphorus, and potassium (NPK) necessary for optimum plant growth.  Make your plants happy with worm castings. Suggested application rate is up to 20% of total soil mix.

Each bag is one gallon of naturally created worm castings.

Note: Worm castings will ship separately from your seed order, direct from the worm farm in California that "makes" them.
