Being a Master Gardener is about learning, volunteering and fun. If you enjoy learning about gardening, sharing your knowledge with others and volunteering in your community, you should consider becoming a Master Gardener Volunteer.

Marion County Master Gardener training requires completion of the OSU delivered Master Gardener course and a 66-hour volunteer service requirement. Volunteering helps you apply the concepts learned in class and supports the public service commitment of the Master Gardener program. When you have passed the training course and completed your required volunteer hours, you will become a Certified Master Gardener.

Training is available in two formats: classroom and online.
Classroom Based Master Gardener Training in Marion County
As a classroom participant you will learn about practical research-based home-gardening from OSU professors and other experts in a face-to- face interactive learning environment.

2019 Marion County Master Gardener Course – Salem
Mondays, January 7 through April 1
9:00 a.m. to 4:00 p.m.

Your training will include topics such as basic botany, entomology, plant disease, soils, water, lawns, ornamental trees and shrubs, pruning, fruits and berries, propagation, composting, organic gardening, weed management, pest management, problem diagnosis and specific information about gardening in the Willamette Valley. You will also learn how to find reputable research-based information you can use to answer difficult questions, because no one knows everything about gardening.

Being a Master Gardener After Training
Once certified, you will have many opportunities for advanced training and volunteer activities. You can attend seminars, teach workshops, make presentations, volunteer in the demonstration garden, participate in community gardening events, answer questions and provide advice at the help desk and plant clinics, work with the Jr Master Gardener program, participate in leadership activities, and more.

To maintain certification, Master Gardener volunteers complete at least 10 continuing education hours and at least 20 hours of volunteer service each year.

Online Master Gardener Course

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.
