Jersey Greensand

Jersey Greensand – NPK 0-0-3

Used as a soil conditioner and fertilizer since the 1700s, Greensand is a long-term, slow-releasing fertilizer of marine origin with iron-potash-silicates and unique properties that loosen clay soils and increase the moisture-holding capacity of both clay and sand. When added to container potting soil, Greensand significantly reduces the need to water.
