Harris Horticultural Charcoal, Premium Biochar Soil Amendment for Plants and Terrariums, 2qt

What is Biochar? Biochar is a type of charcoal made from plant materials such as hardwoods, grasses, and agricultural and forest residues that are decomposed at high temperatures, often during renewable energy production. During the process, the physical and chemical properties of the plant material change into a porous, stable, carbon-rich by-product known as biochar. Why use it? Biochar has been used in agriculture for many centuries. Adding biochar to soil has the potential of increasing soil carbon, soil nutrient content, increased water retention and water-soluble nutrients, and increased beneficial microbial life. DIRECTIONS Best results are achieved when adding this mix to your soil at least 5-7 days BEFORE planting. However, this can be used at any time in the planting process. Optimal ratio for most gardeners is 5-10% biochar in the top 6 inches of their soil. (1 part Bio Char to 9 parts planting soil). Indoor Plants(container plants, seeds, cuttings, transplants): Use a small rake or spoon and hand-mix this product around the plant within your desired container. Best results are adding close to the root zone. You can also just layer a light dusting on the top and water in as usual. Outdoor Plants (Gardens, Bedding Plants, Ornamentals): Use your conventional tiller and rake and till directly into the soil. Adding more over time can increase product performance. Trees and Shrubs: Best when applied to the root zone area. Rake into this area and water as desired. Compost Mix: Mix as needed within your compost process – use as desired as you would your final compost. This product is not intended to be used as a soil substitute.
