Colorado Master Gardeners

Master Gardeners are Important to Our Community

Colorado Master Gardeners (CMGs) are members of our community who love lawns, trees, shrubs, flowers, and vegetables. They are passionate to learn and share their knowledge with others. Master Gardeners are life-long learners who complete an initial training that covers various aspects of horticulture with the intent to teach others while volunteering in our community. Their goal is to help foster successful gardening with Larimer County residents.

Have a yard or garden question? 

Master Gardeners are available year-round and are often found at many community events during the growing season. Send your questions and photos to LarimerMG@gmail.com.

A special program of the Larimer County Master Gardeners is the Tree Team. Diagnosing tree issues can be difficult over the phone or email. Additionally, a large portion of questions Master Gardeners receive are about woody plants. The Tree Team was formed so Master Gardeners could provided site visits to better support residents of Larimer County.
