How to Join

Start by visiting our Marion County Master Gardener Association Website 

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.

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 Junior 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.
