The Tri River Area Master Gardener Program is a vital part of Colorado State University Extension outreach for the counties of Mesa, Delta, Montrose, and Ouray in western Colorado. Our Master Gardener volunteers are our valued partners, helping us provide accurate, research-based information to the members of our communities on many aspects of horticulture.

The Master Gardener Program originated in Washington State in 1973 and rapidly spread across the country. The Master Gardener Program was started to address urban landscaping. The basic concept of the program is that volunteers receive a specific amount of top-quality training from Extension and in return provide back to Extension a specified amount of time and effort. This partnership has been of great benefit to all parties.

The Tri River Area Master Gardener Program began in 1978 with eight volunteers, and has grown to include about 150 members today. Well over 1000 people have gone through the program. During an average year, Tri River Area Master Gardeners assist 10,000 members of our communities in solving their yard and garden problems and becoming better gardeners, thus improving quality of life in western Colorado. Master Gardeners provide educational services to homeowners and other non-commercial gardeners, while Extension agents serve the commercial green industry.

Master Gardener applications accepted August 1-September 15. Find out more
