BIOChar is a natural, carbon-rich upgrade for your soil mix, designed to give roots the space, structure, and support they need to thrive. This lightweight additive is all about balance, it improves drainage, boosts water retention, and holds onto nutrients so your houseplants stay happy, even between waterings. Just add 1–5% to your SYBASoil mix and let the magic begin.
Sybotanica’s BIOChar is produced from PEFC-certified spruce wood in Scandinavia, using a method called pyrolysis at 600°C. The wood is sourced from forests within 80 km of the production site, keeping the environmental footprint low. And yes, it’s organically certified. That means it’s kind to your plants and the planet.
Whether you’re building a terrarium, repotting your Monstera, or creating your own blend from scratch, this BIOChar is a premium, sustainable material that delivers lasting benefits to any potting mix.
Once it’s in your mix, BIOChar gets to work as a powerful soil amendment. Its porous structure acts like a sponge, absorbing moisture and holding onto nutrients so they’re available to your plant’s roots when needed. That also helps reduce nutrient leaching, meaning you’ll waste less fertiliser and get more consistent results.
BIOChar is also great for microfauna. Its texture creates a cozy microfauna habitat, encouraging the growth of beneficial organisms like bacteria and fungi. These tiny helpers improve nutrient cycling and support overall soil health.
This isn’t just a short-term fix. BIOChar increases your soil’s cation exchange capacity, a fancy way of saying it helps your soil store and release nutrients efficiently. It also acts as a natural pH buffering agent, helping keep your soil stable and plant-friendly over time.
Because it’s carbon-rich, BIOChar plays a role in building long-term soil carbon, boosting the health of your substrate season after season. It’s perfect for creating airy, breathable mixes that support root aeration while also locking in the right amount of water. That means less chance of soggy roots and more consistent hydration where your plant needs it most.
Use BIOChar with other Sybotanica staples like Worm Castings, Mealworm Castings, or Lava Gravel for a personalised mix that’s packed with power. It mixes with compost beautifully, bringing structure and sustainability to every scoop.
Sybotanica’s BIOChar is clean, effective, and planet-friendly, a true win-win for you and your leafy crew. Give your soil a long-lasting boost and let your houseplants do what they do best: grow, thrive, and make your space a little greener every day.
