The Earthshine Biochar blend is a fast and easy way to boost the performance of new soil, reuse your old soil, and improve the effectiveness of compost teas and mycorrhizae products. This amazing product will save any gardener money by reducing soil costs, improving fertilizer use and reducing water use over the gardening season. Since this is considered a fermented fertilizer product (and biologically active), please note that over time a fermented wine or yeast smell may occur due to the breaking down of nutrients in the product or soil. This is safe, natural, and completely normal. Store in a cool, dry place and out of direct sunlight until application.
