Still Sleeping on Biochar? Here's What It Does

We talk a lot about biochar. But what is it, really and why does it matter for your plants?

Thousands of years ago, Indigenous communities in the Amazon discovered that burning organic material in low-oxygen pits created nutrient rich soils known as Terra Preta.

Centuries later, Western scientists began testing charcoal in soil. Then In the 1960s and 70s, Dutch soil scientist Wim Sombroek’s research on Terra Preta helped kick off the modern science of this material.

Today, we call this specially made charcoal “biochar.” It’s used around the world for sustainable farming, cleaner water, and locking away carbon to fight climate change, and it’s the not‑so‑secret ingredient in every bag of Rosy.

Here’s what biochar is doing for your plants right now:

Holds moisture - keeps roots hydrated without staying soggy
Stores nutrients - stops the good stuff from washing away
Supports good microbes - creates housing for beneficial soil life
Stores carbon - locks up CO₂ so your garden helps fight climate change
