Enhance your soil with premium BioChar Horticultural Charcoal (1/4"), a highly porous, carbon-rich amendment designed to improve root health, nutrient retention, and microbial activity.

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. Biochar can also be “charged” with fertilizer or compost tea before use to maximize its effectiveness.
