📊 Proven Success in Plant Growth

  • Plants grown with worm castings develop stronger roots, lusher foliage, and faster growth.
  • Slow-release nutrients ensure long-term nourishment without over-fertilization.

💡 Did you know? Unlike synthetic fertilizers, worm castings prevent nutrient leaching, keeping nutrients available for root absorption.

How to Use Worm Castings

🔹 As a Soil Amendment

  • Mix into potting soil to improve nutrient availability and support root development.
  • Recommended ratios:
    • Cacti & succulents: Up to 10% (monitor moisture retention).
    • Young & sensitive plants: 1:2 worm castings to soil.
    • Most houseplants: 1:3 or 1:4 worm castings to soil.
    • For extra fertility: Up to 1:1—adjust watering accordingly.

🔹 Worm Castings Tea – A Liquid Nutrient Boost

  • Add a few spoons of worm castings to lukewarm water, let it steep for a few hours, then use as a nutrient-rich liquid fertilizer.

🔹 Refreshing Soil Nutrients

  • Worm castings remain active in soil for up to 6 months.
  • To refresh soil:
    • Remove 20% of the top layer and replace it with worm castings.
    • Lightly mix in and water to allow nutrients to reach the roots.

How Are Worm Castings Made?

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.
