You can obtain a license to become a Regional Nature Technologies Service Center in your area. Each Center provides professional soil and plant products and services to the Landscape, Agriculture and Retail market -- a safe, environmentally responsible program for healthy plants and soil. This includes supplying non-toxic, organic plant protection products and related services for customers located within a defined territory.
