Linn County Master Gardener training consists of 66 hours of the following activities:

  • Class room instruction one day per week for eleven consecutive weeks during January, February and March
  • Online modules

The cost of this training is $135 to cover the cost of the Master Gardener reference notebook, classroom materials, and classroom expenses.

Returning Hours

After completing the classroom training, Master Gardeners must agree to return 66 hours in volunteering gardening information, public service, or remit $500 for the course.

minimum or 46 hours is spent at the Extension office, farmers market or other plant clinic venue answering gardening questions.

The additional 20 hours can be returned in activities such as:

  • staffing information booths and/or giving demonstrations at the Linn County Fair,
  • co-teaching Seed to Supper classes,
  • working in the demonstration garden located at the Linn County Fair and Expo Center,
  • providing gardening programs for service clubs
  • writing newspaper articles, or taping radio spots.

Continuing as a Master Gardener (Recertification)

Master Gardener certification is only valid for one year. After that each year, MGs must attend at least ten hours of educational classes. Example are webinars, OMGA Mini-College, Insights into Gardening, or PNW classes. Additionally MGs must volunteer for at least twenty outreach hours. This might include staffing plant clinics, working in the demo garden at an event, or teaching a class.

You may renew your certification as many times as you wish. A few have remained active since the first class was held in 1978! Others have remained active since their training. Many become members of Linn County Master Gardener Association. This association holds monthly meetings to become better acquainted with each other, to have fun, to gain additional knowledge, and to plan community and educational gardening activities.

Statewide Resources

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.
