Worm castings are produced through natural composting, where earthworms break down organic materials like kitchen scraps and garden waste. This process enriches the soil with essential nutrients and beneficial microorganisms.
💡 Occasionally, live worms, isopods, or springtails may be present—they further enhance soil health by decomposing organic material.
