You bury it in your garden
and something begins.
The Soil Maker™ is not a product you maintain. It is a living system you invite into your land. Handcrafted from stoneware, made in two pieces, built to last generations. Working quietly beneath the surface, week after week, season after season.
How It Works
Bury it. Feed it. Let it go.
Dig a hole.
Meet the earth.
The Soil Maker comes in two pieces. The bottom chamber, round stoneware with small holes in its base, goes underground. The holes sit just below the soil line. The earth holds it in place. No concrete. No adhesive. Just ground and gravity.
Two pieces · No tools required · Place near where you want the garden to grow
Drop scraps in.
The worms arrive.
The top piece rises above the soil. A tall narrow neck opens into a wide bowl. Drop in vegetable peels, fruit rinds, coffee grounds, eggshells. They fall into the buried chamber. The worms already living in your soil find their way in through the base holes. They eat. They carry. They return to the earth.

Two to eight weeks.
Scraps become soil.
To get started, add redworms directly into the chamber, or build the culture slowly with small consistent amounts over the first few weeks. Once established, what you drop in transforms in two to eight weeks. Bacteria, fungi, worms — all working quietly underground. Your garden gets richer without you doing a thing.
Start with redworms or build slowly · 2–8 weeks once established · No turning required
Every few months,
spread it further.
Every three to six months, lift the top piece. Scoop the living soil from the chamber and spread it into nearby holes you've dug in the garden. Like feeding a sourdough starter. You're not emptying it. You're extending it. Each time you spread, the network reaches further. Slowly, what began in one spot becomes the whole yard.
Spread every 3–6 months · Dig nearby holes · The whole yard comes alive
The Alchemy Pot Initiative
This is not just a composter.
It is a classroom.
Every Soil Maker sold supports the Alchemy Pot Initiative, a national program teaching children in schools and underserved communities how to make soil, inside and out. To transform waste into possibility. Food scraps into earth. Heavy emotions into connection.

One vessel is a beginning.
Three is a conversation.
As you spread composted soil into new holes every few months, you are building physical paths beneath the surface. Tunnels and trails the worms follow between vessels, carrying nutrients as they move. Over time, what started as individual points of life begins to connect. Worm networks touch. Fungal threads extend. The whole yard becomes one breathing system.
