Our Sustainable Plant Food is specially formulated to improve soil health without any synthetic fertilizers (see our mission for our feeling on weird colored balls in soil). In fact, many of our ingredients are grown, so they sequester carbon while they are made and then deliver nutrients right to your plants. The main ingredient in this mix is OurCarbon, a material made of carbon sequestered from organic waste that was diverted from landfill. Super charges up to 66 cups of soil - or - half a cubic foot of soil Climate Impact: 18 lbs prevented carbon emissions
