Join the DCMGA

Prospective volunteers are required to complete the Master Gardener™ Training course, facilitated by experienced volunteers in coordination with the OSU Extension Service.

The course includes a complete review of Sustainable Gardening: The Oregon–Washington Master Gardener Handbook. In the 10-week course (September-November), students receive up-to-date education and hands-on learning from OSU Faculty and local gardening experts.

After completing their initial training, students become volunteers and they are able to give their time through our many community outreach programs including The Plant Clinic and The Discovery Garden.
