WM EarthCare™ Homegrown Compost is made from Bay Area yard trimmings and residential food scraps at our windrow composting facility in Marin County. It is processed to be stable and mature and is tested to be free of pathogens and chemicals.
Compost releases nutrients slowly, contributes to soil structure, and helps with water retention and drainage. Compost may be applied year-round and is especially beneficial in the fall and spring. The recommended application is 2″- 3″ in depth.
WM EarthCare™ Homegrown Compost is a recipient of the US Composting Council Seal of Testing Assurance (STA), the Organic Materials Review Institute (OMRI) listing for use in organic farming, and the California Department of Food and Agriculture nutrient label, the industry standards for quality.
