Do you love to make things grow? Apply to join our cohort of plant enthusiasts in Linn and Benton Counties. As part of the Master Gardener volunteer team, you will build your gardening knowledge and share what you learn with our communities.

Who are Master Gardener volunteers?

Master Gardener volunteers are people just like you who are excited about making things grow.  They are from all walks of life, but they are all part of a team that works together to:

  • Learn how to grow plants for food and beauty.
  • Discover tested and trusted resources.
  • Solve plant problems.
  • Teach what they discover.

As a Master Gardener volunteer educator, you will complete a university-taught course about the nuts and bolts of growing. You’ll join a cohort of new and experienced volunteers and connect with a community of fellow plant enthusiasts. Then, you’ll contribute 66 hours of volunteering to share research-based sustainable gardening practices to promote healthy landscapes, healthy foods and healthy lives.

You can help grow knowledge, gardens and communities. Join us.

Becoming a Master Gardener

Master Gardeners spend one day each week for eight consecutive weeks during January through March in the class room + online modules + hands on workshops for a total of 66 hours of instruction. It is helpful if potential Master Gardeners have had some gardening experience, but it is not required.

Some typical training topics include:

  • botany essentials
  • soil management
  • plant nutrition
  • pest identification and control
  • diagnosis of plant problems
  • growing vegetables
  • sustainable landscape design
  • fruit trees
  • and more

Cost

Each new Master Gardener who is accepted for training pays $140 to cover the cost of the Master Gardener reference notebook, class materials, and classroom expenses.  

Thanks to support from our nonprofit partners, a limited number of partial scholarships are available, please contact elizabeth.records@oregonstate.edu for more information.

Volunteer service

To become Master Gardeners, volunteers complete 66 hours of volunteer service.

  • 46 hours is spent at the Extension office, farmers market or other plant clinic venue researching and resolving gardening questions for our communities.
  • Volunteers can fulfill the additional 20 hours of service in activities like cultivating our demonstration gardens, supporting educational activities, staffing community events and more.
