by: Espoma
Espoma Organic Charcoal is an all-natural high carbon material that is used to help improve soils. Using a process called pyrolysis, it is created by heating untreated hardwoods to very high temperatures without oxygen, resulting in an excellent soil conditioner. It can improve potting mixes and in containers can add better drainage.
