Master Gardener Online

Option 1: Certified Master Gardener

Open to Oregon residents only. Non-Oregon residents see Option 2.

An Alternate Route to Becoming a Certified Oregon State University Extension Master Gardener Volunteer (open to Oregon residents only).

Would you like to become a Master Gardener Volunteer? FIRST, contact your local Extension Office to find out what live training they offer - this is the best route to becoming a Master Gardener.

If the timing of the live training doesn't work for you, this Instructor-led Online Training is an excellent alternative. The curriculum includes:

  • Recorded lectures on a variety of required topics
  • Additional lectures for optional specialized knowledge
  • Lively forum assignments and discussions with other students
  • Weekly quizzes to help you retain information
  • Extensive additional resources to help ensure your long-term success

To become a Master Gardener in your county and receive a badge, take this course and pass the final exam, then complete 40 to 70 hours (varies by county) of on-site volunteer practicum. You will apply the concepts you learn in the online training course to community volunteer opportunities through your local Extension Master Gardener Program.

Master Gardener volunteers must complete volunteer and continuing education requirements to maintain certification.

Option 2: Certificate of Home Horticulture

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.

You will receive a Certificate of Home Horticulture upon successful completion of the online course.

Online Master Gardener Overview

The Master Gardener and 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.

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.

What You'll Cover in this Course

  • The basics of botany and entomology
  • Integrated pest management and pesticide safety
  • Soils, fertilizers and composting
  • Ornamental, herbaceous plants and woody plants
  • Vegetable, indoor and container gardening
  • Sustainable landscaping
  • Plant pathology

I wanted to become a Certified Master Gardener in OR. I loved the flexibility as I was on the East Coast at the time. The instructor provided wonderful feedback and tried hard to engage us, which can be hard in an online format. After completing the online course, I was able to get my volunteer hours in so that I am now a certified OR MG!

Beth Ewy

I learned a lot about the PNW flora, conifers and how to better amend my soil. The instructor was great, very responsive. I enjoyed the practical requirements. If you’re interested in learning about the diversity of this region, and how to better take care of plants, then absolutely I would recommend the program.

Donna DeViney
MG

I now have a new network and I've helped people learn how to garden without chemicals. After the course, I've helped grade school kids to like worms by teaching a class in 5th and 6th grade. I loved it all.

Rob Kappa
MG

The convenience of taking the class online was priceless. I was concerned I'd have enough time to put into the course given my busy schedule, but I was able to successfully complete the course working two jobs, plus the support of my full-time employer who let me change my lunch schedule to allow time to study. It was a great accomplishment for me and proved to me I can do whatever I put my mind to doing. I learned new skills and concepts and have a ton of resource material to refer back to as needed. I can't speak highly enough about the experience overall.

Barbara Corley
MG

I enjoyed the opportunity to learn about gardening from professionals but in online fashion. Completing this online master gardener program and earning a certificate in horticulture inspired me to further pursue the UCONN Master Gardener program this year and earn my formal certification. UCONN Master Gardener class of 2018!

Mary PowellStLouis
MG

I love gardening and wanted to meet more people that share my passion. Through this program, I met some wonderful people - actually, I met more of my neighbors through this program! The people I worked with were so interesting! Learning online was wonderful for someone working full time. The volunteer opportunities were also flexible, making it easy to complete 60 hours. I hope to see more young people and will encourage others to try this program.

Margot Wheeler
MG

I learned a ton and yields are up. I now have a scientific approach to organic food production. I enjoyed learning botany, soils, entomology and herbicides & pesticides. It was rigorous, but fun.

Suzanne Porter
MG

I like wearing my Master Gardener fleece vest and being approached by people with gardening questions. I also like having my gardening knowledge legitimized! This program enhances gardening knowledge, which is important because so many people have gardens/yards and feel frustrated about how to take care of it. My favorite part were the discussions and learning how to approach specific problems and hearing from others on what NOT to do, or from others’ bad experiences.

Stephanie Pringle
MG

I incorporated what I learned in teaching the general public about gardening and it greatly enhanced my classes. I enjoyed the online flexibility, quality instructors, and the ability to revisit lectures via weblink. I would recommend this program due to the benefits mentioned above, plus the quality, research-based information. OSU made online learning easy and I highly value the quality content and instructors.

Sherry Sheng
MG

This was something I always wanted to do. The daytime class didn’t work for me because of work. After taking the class, I was able to step into the Plant Clinic and stay with it. I loved the diagnostic section and the online flexibility for a working person. I had a great experience and would do it again.

Jan Gano
MG

 I wanted to be a better gardener. The course was a great education on all aspects of gardening. This summer I helped a work-colleague turn her front yard into a meadow of wildflowers with knowledge I learned. I visited it recently and it's beautiful!

Cynthia Chase
MG

I learned a lot and met great people and got involved in the community. The time involved compared to the amount I learned was well worth it. A lot of what I learned involved practices that everyone should know, IPM, when and how to use a pesticide if necessary, safe practices that help Mother Earth, etc. It was a great and thorough program.
