Are you interested in learning about gardening in Central Oregon? Are you willing to share your time and knowledge with your community? Become an OSU Master Gardener™ volunteer!

The OSU Master Gardener™ Program in central Oregon is entering its 43rd consecutive year, serving Crook, Deschutes, and Jefferson Counties. Over the years, this program has trained hundreds of volunteers and they, in turn, have reached thousands of clients within our communities.

The OSU Extension Master Gardener Program educates Oregonians about the art and science of growing and caring for plants. The program targets individuals interested in learning and sharing research-based gardening information. Currently, the program has over 90 active volunteers who find the program educational, fun, and very rewarding.

OSU Master Gardener trainees receive 48 hours of intensive classroom training followed by 48 hours of experiential learning. The OSU Master Gardener Program consists of two parts:

Classroom training (hybrid in person and online in 2024)
Experiential learning in the plant clinic and community outreach activities.

An individual must complete both parts to successfully become an OSU Master Gardener by October 31, 2024.

Classroom training dates are listed in the application. The cost of the program is $280 for the class of 2024. Partial scholarships are available, call 541-548-6088 to request more information.

Part 2: Experiential Learning/Volunteer Hours

As with any other learning process, hands-on experience is always beneficial and quite fun! In addition to classroom training, trainees are required to volunteer a total of 48 hours in experiential learning to complete their training. This involves working at the OSU Demonstration Garden in Redmond (3 hours required) unless physically unable. The remaining 45 hours of your experiential learning is completed through a variety of community outreach activities (see application).

At the completion of your experiential learning, you will become a certified OSU Master Gardener™. You will need to re-certify on an annual basis to keep your certification status. The OSU Extension Service reserves the right to interview applicants by phone or in person for final selections.
