This low-cost, biodegradable, mulching paper is designed to be used for one growing season and can be tilled in. When the edges are secured, the crepe in the thin paper allows it to hug the soil and to efficiently pass on the heat it absorbs, giving crops a boost early in the season. Porous to water, it effectively suppresses weeds and keeps vegetables from contact with the soil, reducing spoilage. It is made from recycled paper containing a resin binder and an anti-microbial to stop decomposition at the paper/soil interface (may not be acceptable for organic). Black.
