raw hemp char (1.1lb packaged in a reusable bag)
Usage: As a soil amendment, we recommend 2-3 cups of biochar per square-foot of garden space, or 2-3 cups per pot. Healthy soil should have 5-10% biochar for the purpose of nutrient retention and healthy bacterial growth.
Existing lawns, shrubs, trees and gardens
You can use biochar over the ground and rake it in thoroughly. You can spread 1 cu/ft box of biochar over ~350 sq/ft of soil. This is a typical application for existing lawn care.
- 1 cu/ft bag = ~375 sq/ft.
- 1 gallon bag = ~55 sq/ft.
*Reapplication of biochar each year is recommended for several years.
An alternative would be to apply a 50/50 mix of biochar and organic compost to the planting area. This new mix will work its way into the existing soil.
