How Biochar with CarbonBoost™ supports soil
Biochar supports soil structure and helps retain water and nutrients around roots. Its porous structure also creates habitat for beneficial soil microbes.
CarbonBoost adds humic acid, mycorrhizal fungi, and beneficial bacteria to support soil biology from the start. The blend is pre-moistened and ready to mix into soil.
How to use Biochar with CarbonBoost™
For garden beds, raised beds, containers, and lawn repair projects, mix thoroughly into soil or growing mix at about 5–10% by volume of the finished soil mix.
As a quick planning example, one 1 CF bag can cover about a 4 ft × 8 ft bed mixed 6 inches deep.
No additional charging is needed. Mix into soil as directed and water in. Continue using compost or fertilizer as appropriate for your plants and soil conditions.
Using CarbonBoost in lawns and repair areas
For new lawns, seeding, or sod, mix into the top layer of soil before planting. For existing lawn repairs or patches, aerate, spread by hand or shovel, then rake into the openings. Spreading and raking without aerating is another option; small garden spreaders can clog.
