Copper For The Garden: What Copper Does For Plants

2021-4-6  Copper is an essential element for plant growth. Soils naturally contain copper in some form or other, ranging anywhere from 2 to 100 parts per million (ppm) and averaging at about 30 ppm. Most plants contain about 8 to 20 ppm. Without adequate copper, plants will fail to grow properly. Therefore, maintaining fair amounts of copper for the ...
