Info

Douglas County Master Gardeners provide useful information to help your gardening efforts all year long. Through the Douglas County Extension Office, trained volunteers are available to answer horticulture questions about vegetable gardening, flowers, trees, shrubs, lawns, pruning, watering, plant disease and diagnosis, insect problems, composting, and environmental concerns.

Our volunteer Master Gardeners are now on winter help desk hours.  The winter help desk hours are answered by email only.  Please email dcmgardenr@gmail.com if you have any questions.

Douglas County Master Gardeners are also available to give talks to community groups on a variety of gardening topics. We are available to speak on flower or vegetable gardening, landscaping, xeriscaping, houseplant care, turf management, insect and weed control, and other home horticulture subjects with particular emphasis on Douglas County–Where ever you are, we’re local! The materials contained in presentations are the most up-to-date, research-based information from Colorado State University.

View Training Schedule

Our program’s training includes both in-person and online classes offered through CSU Online. Courses are specific to Colorado’s climate, soil, environment, insects, wildlife, and plants. Training is a big commitment and includes reading (online, no text required), homework, in-class activities, and lectures. You will be expected to attend 80% of the classes and pass the final exam (open book, open note, researching encouraged) with a 75% or better.

Colorado Gardener Certificate Student

Individuals interested in completing Master Gardener training without a volunteer commitment may enroll for the coursework under the Colorado Gardener Certificate, CGC, enrollment option. The Colorado Gardener Certificate program requires a fall application followed by winter and spring training classes.  Individuals who were not selected as CMG volunteers may enroll as Colorado Gardener Certificate students. Applications for 2021 will be available in fall 2020. If you would like to be added to our notification list, please contact the CSU Extension Office.

CMG/CGC Certification

Students who are accepted into the Colorado Master Gardener program and complete the required volunteer commitment, become Colorado Master Gardeners. The title Colorado Master Gardener is a registered service mark of Colorado State University Extension. It is used to identify volunteers serving in official CSU Extension activities. It may not be used to infer credentials, imply endorsement of a private business, or used on marketing materials of a business. Students who choose the Colorado Gardener Certificate option will not become Colorado Master Gardeners upon completion of the training.

Colorado Master Gardener Volunteers and Colorado Gardener Certificate students both receive the Colorado Gardener Certificate, which may be displayed in a place of business and used in business marketing.
