What is a Master Gardener?

Colorado Master Gardener Volunteers assist CSU Extension staff in delivering knowledge-based home gardening information to the public.

The Colorado Master Gardener (CMG) audience is exclusively home and community gardeners. CMG volunteers serve the public by answering questions from citizens of Weld County about home gardening, staffing diagnostic clinics, teaching gardening classes, writing newspaper articles, and mentoring gardening and community greening projects.

State-wide, over 1,500 CMG volunteers serve 43 county-based programs and contribute over $1.3 million in volunteer time annually!
