Eric Fleisher of F2 Environmental Design has been breaking new ground – literally ­– ever since he first began converting New York public landscapes to organic management 30 years ago. By building up and managing the soil, and treating the landscape as a holistic system, he eliminates the needs for chemical inputs and turns garden wastes into an environmental resource. In this way he has transformed landscapes all over the country, from the Harvard University campus to the Museum of Modern Art Sculpture Garden.
