In 49 states (and four Canadian provinces) where the program exists, Master Gardeners (MG) are trained and supervised by the Cooperative Extension Service (CES). In fact, the CES created the MG Program. When you work as an MG, you are representing the CES in your state. enesis of CES The CES grew out of the U.S. Congress’ concern for the education of the average citizen. Prior to the Civil War, few college curriculums addressed the problems of citizens making their livelihood from agriculture. In 1862, congress passed the Morrill Act, which provided a university in every state that would educate citizens in agricultural and mechanical fields. These colleges are known today as “land-grant universities.” Congress soon realized that to be effective, the educational function of land-grant universities must be supplemented with a research capability. Consequently, Congress passed the Hatch Act in 1887. This act enabled the establishment of facilities where colleges could conduct research into agricultural, mechanical and related problems faced by the rural citizens and the general public. You may have passed one of these research stations on a trip or even know of one near your home.
