BioChar Horticultural Charcoal - 1/4"

BioChar Horticultural Charcoal (1/4") – Pre-Activated with Compost Tea

Enhance your soil with premium BioChar Horticultural Charcoal, a highly porous, carbon-rich amendment that improves root health, nutrient retention, and microbial activity. Produced from natural organic materials through a controlled pyrolysis process, biochar creates a stable structure that can remain in the soil for years.

Ours arrives ready to use. Raw biochar is essentially an empty sponge — added straight to a mix, it will pull nutrients out of your soil before it begins releasing any back. That is why biochar needs to be "charged" first. We have already done that step for you: our biochar is pre-activated with compost tea, so it goes into your mix loaded with nutrients and beneficial microbes from day one. No soaking, no waiting, no nutrient lockout.

Our 1/4" particle size is ideal for bonsai, tropical plants, houseplants, succulents, cacti, raised beds, and garden soils, providing excellent aeration and drainage without breaking down quickly.

Why Use BioChar?

Biochar acts like a microscopic sponge, storing water, nutrients, and beneficial microbes in its porous structure. When incorporated into your growing media, it creates a healthier root environment and can improve overall plant vigor, resilience, and growth over time.

Common Application Rate

Use as 5–15% of your soil mix depending on the crop and growing conditions. Because it is already activated, simply blend it in — no pre-soaking or charging required.
