Biochar: Terra Preta – The Magic of Ancient Black Dirt
“Soil so good it fed civilizations” — now in your hands.
🌱 Perfect for indoor & outdoor plants, garden beds, trees, pots & planters
What Is Biochar?
Thousands of years ago, ancient Amazonian civilizations turned poor jungle soils into rich, black earth — called terra preta. They slowly burned plant material in low oxygen environments into charcoal and mixed it into the soil. The result? Thriving farms and enormous populations sustained by healthy, productive land.
Now you can harness the same ancient magic.
🌱 What Does Biochar Do?
Biochar is more than just carbon — it’s a powerful soil enhancer that improves structure, stores nutrients, and supports living soil biology.
Microbe Superhighway
The porous structure acts like a network of tunnels for beneficial bacteria and fungi — helping them move, multiply, and colonize your soil.
Healthier, Stronger Roots
Improves root mass, water uptake, and nutrient absorption for faster-growing, healthier plants.
Nutrient & Water Retention
Adding 5% biochar increases your soil’s water retention by 20 percent! It also helps retain nutrients in the root zone where your plants can use them.
Indoor & Outdoor Use
Safe and effective for houseplants, containers, garden beds, trees, lawns, and more.
The Science & Substance
Biochar is permanent carbon locked away in your soil.
-
Lasts for centuries: Biochar has been found in 1,000+ year-old soil, still active and effective
-
No pine, no bark, no contaminants: Our product avoids the issues common with tree- or wood-based char
🌼 How To Use
Mix into soil or potting mix:
-
2%-5% of your total soil volume, depending on how you would like to invest in your soil
-
Or top-dress 1–2 ounces per plant, and gently mix into the surface. Watering will eventually move it into your plants roots and soil.
Water will carry the biochar downward over time. Safe to use every few months as part of a soil-building program.
