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.

Volunteers are no longer staffing the office. Volunteers are available via email year-round to answer all of your gardening and home horticulture questions! Please email for help.

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. The materials contained in presentations are the most up-to-date, research-based information from Colorado State University. Local Douglas County climate and garden conditions are also targeted.

Enrollment Options and Class Information

Colorado Master Gardener Volunteer

The Colorado Master Gardening (CMG) training program requires a fall application and interview followed by winter and spring training classes. Tuition for CMG Volunteer training in 2018 was $170 plus a commitment to complete at least 50 hours of volunteer work the first year.

Applications are due by October 30, 2018 with an interview and background check to follow, before being accepted into the program. Once you have been accepted, payment will be due by December 31, 2018 or you will incur a late fee.

As a volunteer, you’ll assist Douglas County Extension staff and fellow Colorado Master Gardeners in delivering research-based information about home gardening to Douglas County residents. To maintain your CMG status on a yearly basis, you’ll be required to pay nominal yearly dues and complete additional volunteer hours (typically 24 hours) and continuing education classes offered through CSU and the community.

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.

As an accepted CMG/CGC student, you’ll complete a curriculum that includes ten weeks (60 hours) of classroom instruction. Classes are held January through April through a combination of in-person (weekday 9AM-4PM with a lunch break) and online classes.
