The 1921 French Garden Method Soil Science Quietly Walked Away From — And a North Carolina Workshop Is Bringing Back

In a small workshop behind a quiet house in West Asheville, a 78-year-old retired toolmaker is hand-winding the last 400 copper garden stakes from a French gardening tradition most American gardeners have never heard of.

Henri Brossard in his West Asheville workshop, holding a finished hand-formed Brossard copper stake. Slender copper rod, ring-binding, helical-wrapped stem, and the trademark flat spiral coil head — each one still wound on the walnut mandrel his grandfather hand-turned in the Vendée in 1921.

Most American backyard gardeners have never heard the name Georges Lakhovsky. They have certainly never seen one of his copper coils. And yet a small workshop in West Asheville, North Carolina, has been hand-winding the same coils, on the same walnut-wood mandrel, in the same family, since 1921 — quietly, without a website, without a sign, without explanation.

The mandrel is six centimeters across. It was hand-turned in the Vendée region of western France by a man named Henri Brossard, who attended two of Lakhovsky’s gardening lectures in Paris in 1921. Two years later, he carried it across the Atlantic in a wooden trunk along with a leather-bound notebook full of penciled sketches. He bent his first American copper coil in a North Carolina barn in 1924. The mandrel has been winding coils ever since.

His grandson, also named Henri, is the one bending them now. He is 78. There are 400 stakes left in a wooden crate behind his workbench. After that, the mandrel goes.

Why the Soil Question Got Quiet

For most of the twentieth century, American soil science went in one direction: feed the plant, not the soil. Synthetic nitrogen, potassium, phosphorus — delivered in measured doses, root-zone application, predictable response curves. It worked. Yields climbed. Backyard gardeners followed the same playbook, scaled down: a bag of granular fertilizer in spring, a bottle of liquid feed mid-season, repeat.

What got lost in that arc was the soil itself. The living layer — the bacteria, the fungal threads, the microscopic invertebrates that compose what gardeners a hundred years ago simply called “good ground” — thinned out, year by year, plot by plot. Most American backyards today have a microbial population a fraction of what their grandparents’ gardens carried. The plants still grow. The soil no longer remembers how.

In the last decade, that has started to shift. A new generation of backyard gardeners, permaculture practitioners, food-forest tenders, and heritage-seed savers has been reaching back — past the bottle, past the bag, past the entire post-war fertilizer model — and asking older questions. Questions their great-grandparents would have recognized. Questions Vendée market gardeners in 1921 already had answers to.

The Brossard workshop sits at one end of that reach.

The Man Who Found the Notebook in a Garage

Henri Brossard, 78, lives in a 1942 craftsman house at the western edge of Asheville, where the city ends and the Blue Ridge foothills begin. He is a retired toolmaker. He spent his working life making precision parts in small batches — the kind of work that teaches a man what a millimeter feels like under his thumb. He retired in 2013 and started spending most of his time in the workshop behind the house.

The workshop is the same one his father used. His father was a quiet man who almost never spoke about France. The grandfather, the original Henri, had died in 1962, when the present Henri was fourteen. The leather notebook had been in the garage corner since the funeral. Henri did not open it until 1998.

He was fifty when he sat down with it for the first time. The pages were brittle. The pencil had faded. The French was old and regional — some of it he could read, some of it he could not. But the sketches were exact. Coil dimensions in millimeters. Spiral counts. Wire gauge. A diagram of how the finished stake should sit in a tomato bed. And a note in the margin of the third page, in the grandfather’s hand, that translated roughly: “The wood holds the wire. The wire holds the silence. Do not change either.”

That winter, Henri sat down at the bench with a length of pure copper wire, the grandfather’s two flat-nose pliers from Nantes, and the walnut mandrel. It took him eleven months to wind a coil that matched the master sketch on page three.

What Makes a Brossard Stake a Brossard Stake

The stakes are not complicated. A length of 99.9% pure copper, 32 centimeters long, with three distinct structural elements wound by hand. What makes them different from the imported copper wire-work sold by the dozen on internet marketplaces is not what they do. It is how they are made.

A side-by-side test in an Asheville backyard, photographed in late summer. Two identical raised beds, same heritage tomato varieties, same soil, same season. The right bed received five Brossard copper stakes at planting; the left bed received none.

A similar test in a backyard kitchen garden: lacinato kale and butter lettuce, both beds planted the same week. The right bed received four Brossard copper stakes at the start of the season; the left did not.

Why the Workshop Is Closing

The diagnosis came in the winter of 2022. Arthritis in the right thumb and the right index finger — the two fingers that bear the load when a Lakhovsky coil is wound. The Brossard coil requires a specific pressure: too much and the pure copper wire kinks at the third winding, too little and the spiral sits loose against the mandrel and rattles when shaken. There is a window of maybe ten percent of human grip strength where the coil sets right. Outside that window, the coil is wrong, and Henri has never sold a wrong coil.

Henri used to wind twenty-five stakes a day. He winds four or five now. Some mornings, the thumb cramps after the second coil and he sets the wire down and walks out into the garden.

“My thumb cramps after the second coil now. It used to be the twenty-fifth. The wire knows. The wood knows. Now I know.”— Henri Brossard

There are 400 stakes left in a wooden crate behind the workbench. When the last one is wound, the mandrel will be wrapped in oilcloth and passed to a younger member of the family who has been apprenticing on weekends. The notebook will go in the same parcel. The workshop will go quiet.

This is not a sale. It is the last batch of a hundred-and-three-year unbroken tradition. After 400, there are no more Brossard stakes in the world.

The wooden crate behind the workbench. Four hundred remaining. After the last is wound, the mandrel passes to the next generation.

Why the Price Is Low

Henri’s toolmaker pension covers his living. The Asheville house is paid. His daughter set up the online storefront on a Sunday afternoon in the spring of 2026 and helped him write the listing. She wanted to price the stakes at three times what they are listed for. A hand-formed pure-copper stake of this length, made on a century-old mandrel from a documented French gardening tradition, would not be unusual at $80 or more from a custom blacksmith. Claire wanted that price. Henri refused.

“I do not want my grandfather’s stakes in a collector’s display case. I want them in a tomato bed. I want them where someone will look at them in twenty years and remember the old man who made them.”— Henri Brossard

The price is set to a level that a young permaculture family in Asheville can afford. A backyard gardener in Vermont. A retired couple in Oregon starting a raised-bed garden for the first time. The people the grandfather, walking off a boat in Charleston in 1923, would have recognized as his own. The low price is not a clearance. It is an invitation.

What Lakhovsky himself reported about copper coils in his 1925 work Le Secret de la Vie — that Vendée market-garden plots planted alongside his coils produced harvests his own field notes described as “far exceeding” the controls — is not Henri’s claim. Henri does not make claims. He makes coils. What he says is this: every stake has been hand-wound on the same mandrel his grandfather turned in 1921. What it does in your garden is between you and the soil.
