    Training Options

    Option 1: Master Gardener Volunteer Educator Training - $495

    (Discount price $445 before January 15, 2018). 

    Learn about sustainable gardening in a fun, friendly environment and help your community grow!  Take a 56-hour training and contribute 56 hours of volunteer service toward OSU's horticulture education outreach program.  The MG Volunteer Educator Training is the equivalent of a college-level horticulture course focused on sustainable gardening.  It is coupled with a volunteer internship in which you apply your learning toward approved volunteer activities to help educate the public using research-based information. This MG program is an investment in your potential to serve as a garden-based educator in the community.  Join us to build your foundation as a community educator with OSU!  The MG program requires a season-long commitment (at least 112 hours total from February-September) to complete both the training and volunteer components of this community-based education program.

    Option 2: Certificate of Home Horticulture - $695

    Receive a Certificate of Home Horticulture upon successful completion of the course, which includes in-person classes, online content, hands-on workshops, gardening seminars, and final exam.  Learn the research-based content of the OSU Extension Master Gardener program without the volunteer commitment required to become a Master Gardener Volunteer Educator.  Participants who do not wish to become a Master Gardener Volunteer Educator (see Option 1 above) can still take the Master Gardener curriculum for their own personal and professional development.  The MG curriculum is the equivalent of a college-level horticulture course focused on sustainable gardening.  Have fun and connect with other garden enthusiasts.

    Option 3: Reduced-fee slots to become a Master Gardener Volunteer Educator

    Application period closed. 

    We are able to provide a limited number of reduced-fee positions in the Master Gardener Volunteer Educator Training as part of our fellowship program.  You will receive the same educational and volunteer opportunities as Option 1 above.

    • Scholarship (You pay $75 materials fee + $175 program fee = $250) Available to participants that don’t meet the Federal Poverty Guidelines, but can’t afford the full cost of the Master Gardener training.  We are looking for volunteers with special skills (bi-lingual, expereince educating diverse audiences) for these reduced-fee slots. Payment plans are available if you pay by cash or check.

    Here are the criteria for these reduced-fee positions:

    3. You have financial need based on Federal Poverty Guidelines.
      • If your annual income is below 50% median income based on the criteria listed at the link above, you are eligible to apply for a FELLOWSHIP option.

    Online Master Gardener Course

    Master Gardener Program Resource

    The Master Gardener & Home Horticulture Basic Training course is designed for anyone who is interested in learning more about the effective and sustainable management of their home horticultural landscape. There are no course prerequisites, although a basic understanding of plants is helpful.

    Option 1: An alternate route to becoming a Certified Oregon State University Extension Master Gardener Volunteer, if the timing of the live training doesn't work for you.

    Option 2: The same training Master Gardeners receive in Option 1, for those who want the training but do not want to become a Master Gardener Volunteer. Participants receive a Certificate of Home Horticulture upon successful completion of the online course.

    In this course you will learn about the art and the science of caring for plants. We examine plant types (e.g. woody, herbaceous), garden types (e.g. container, vegetable), and elements that influence the growth and vigor of plants in the home garden (e.g. pathogens, soils, insects, management decisions). We will also focus on the prevention and diagnosis of plant problems, as well as a least toxic approach to tolerating and/or managing plant problems in the home horticultural landscape.
