About Zazen Tree
A ancient art form.
A modern tool.
A better way to grow.
Zazen Tree is a small-batch bonsai substrate company built by someone who couldn't find soil guidance he trusted — so he built a tool to generate it, then started mixing it by hand.
"Every tree has a biology. The Lab maps that biology to a substrate — species by species, ratio by ratio — so the soil your tree grows in is built around what it actually needs."
The background
Tech first.
Bonsai second.
I came to bonsai the way a lot of people do — looking for something that wasn't a screen. I spend most of my time in tech, thinking about systems and problems and efficient solutions. Bonsai was supposed to be the opposite of all that.
It worked, mostly. Except for the soil.
Every species has different drainage requirements, different moisture needs, different root systems. The guidance online was scattered, conflicting, and often generic. I kept second-guessing every repot. That anxiety was the opposite of what I was going for.
The solution
So I built
a tool.
The Soil Lab is an AI-guided blend configurator. You search your species, it recommends akadama, lava rock, and pumice ratios based on that tree's native habitat and root biology — then explains why. You can adjust the sliders, accept the blend, and order it.
I mix every order by hand in Buffalo, NY. Small batch. Fresh substrate. Shipped within a few days.
It started as a personal project. Then it seemed like something other people might actually want.
The goal was always for it to feel more like a tool you want to play with than a form you have to fill out. Pick a species, watch the blend update, adjust the sliders. The science is underneath it — the experience should just be satisfying.
The name
Zazen is the practice of
just sitting.
The philosophy
Zazen is a form of seated Zen meditation — the discipline of being present without agenda. It's not about achieving anything. It's about showing up, being still, and letting the practice do its work over time.
The parallel
Bonsai works the same way. A tree you're shaping today won't look the way you want it for years. That's not a problem — it's the point. The daily attention, the small decisions, the patience — that's where the calm lives.
The reason
I named this Zazen Tree because the whole point of keeping bonsai — for me, anyway — is to have something that pulls you back to the present. Not a screen, not a deadline. Just a tree that needs water.
Why soil
Everything starts underground.
Bonsai substrate isn't really soil in the traditional sense. It's a precise blend of inorganic materials — akadama, lava rock, and pumice — engineered to drain fast, hold just enough moisture, and give roots the oxygen they need. Get it wrong and nothing else matters.
The ratios change by species. A Japanese Black Pine wants almost no moisture retention — high lava, low akadama. A Japanese Maple wants the opposite. A Ficus wants something in between, with extra pumice for indoor aeration.
Most hobby bonsai soil comes pre-bagged and generic. It works okay for the most common species under average conditions. It's not dialled in to your tree, your climate, or your watering habits.
Zazen Tree exists because that gap bothered me enough to do something about it. The Soil Lab is the tool. The hand-mixed substrate is the product. The goal is to take one source of anxiety out of a hobby that's supposed to reduce it.
