Training Options

Option 1: Master Gardener Volunteer Educator Training - $495

Register for Option 1 (With volunteer commitment)

(Discount price $445 registering before January 11, 2019)

Learn about sustainable gardening in a fun, friendly environment and help your community grow!  Take a 50-hour training and contribute 50 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 100 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

Register for Option 2 (No volunteer commitment)

Receive an OSU Extension Service 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.
