April 18 2026

Learn how to build healthy soil that forms the foundation of a thriving garden by combining compost, native soil, manure, and worm castings to support diverse microbial life and long-term plant health.

Key takeaways for building a strong base soil mix:

  • Mix compost with native soil: Blend a 2–4 inch layer of humic (fully decomposed) compost into existing native soil to create a healthy, fertile foundation.

  • Use diverse compost sources: Combine plant-based compost and animal manure to support a wider range of beneficial microbes and improve soil biology.

  • Add chicken manure carefully: Composted chicken manure is a nutrient-rich fertilizer, especially high in nitrogen. Apply a light layer (about ½–1 inch) before mixing it into the soil.

  • Incorporate worm castings: Worm castings introduce beneficial bacteria and microbes that support plant health. While purchased castings are helpful, living worms in the soil are even more beneficial.

  • Maintain proper moisture: Test soil moisture by hand to ensure it is evenly hydrated. Water slowly and in multiple passes so moisture reaches deeper root zones instead of staying at the surface.
