Tribute to Eddie King
On July 19th, 2025, our team at Hiwassee Products lost a great friend, mentor, and member of our extended family with the passing of Eddie King, a livestock and vegetable farmer of many decades in Chester, New York. Eddie’s passion for pursuing new, better methods to grow vegetables in a market farm environment led him to pioneer many practices that contributed to greater awareness of soil health and nutrient quality. Eddie was an inspiration and frequent collaborator during the development of Hiwassee Products, and his input, patience, and enthusiasm will be missed. His son Jeff continues his legacy and farming operation in the Hudson Valley.
