The Colorado Master Gardener Program

Colorado Master Gardener Volunteers

Colorado Master Gardenerssm are CSU Extension volunteers trained in horticulture and work out of the local county extension office. We extend research based education throughout Colorado to foster successful gardeners, develop partnerships and build stronger communities.

We may do this through:

  • Educational workshops
  • Speakers' bureau
  • Farmer's market, garden show and fair booths
  • Answering questions through email, on the phone or in person
  • Mentoring community and school gardens
  • Mass media such as blogs, newspaper, radio, podcasts
  • Identifying plant pest problems
  • Demonstration and research gardens

Contact a CMG Volunteer about your yard and garden questions.

Search online yard and garden publications.
