What does it take to become a Master Gardener™ Volunteer?

The Master Gardener™ Program of Oregon welcomes enthusiastic gardeners with a willingness to share their interest and experience with the public. To become a Master Gardener you must take the Master Gardener Basic Training Program offered through a OSU County Extension office. For further information on Oregon chapters we have provided  links to each county chapter on this web site.


We are committed to sustainable gardening through:

  • Partnering with the OSU Master Gardener Program to promote sustainable gardening practices.
  • Advocating for funding to deliver the Master Gardener Program across Oregon;
  • Fostering quality continuing education of all Master Gardeners.


Enable OSU Extension Service Master Gardeners as the premier source of information on sustainable gardening.

What is OMGA™ and what does it do for you?

The Master Gardener™ Program was established by the OSU Extension Service to help disseminate horticultural information to the public. Volunteers are trained in participating counties and serve under the direction and guidance of County Extension Agents.

Many volunteers in OSU’s Master Gardener Program choose to associate themselves as members of their county Master Gardener Association Chapters.  Membership in these chapters brings with it membership in the statewide organization, OMGA™.

While OMGA and its subsidiary Chapters were created principally to support and supplement OSU’s Master Gardener Program, OMGA and the Chapters are separate entities, distinct from the Master Gardener Program itself, OSU.  OMGA acts autonomously and is governed by a Board of Directors consisting of a State Representative from each of its chapters. OMGA is a tax-exempt organization 501(3)(c) Incorporated in the State of Oregon.
