Home Horticulture Summer Intensive

YOU ASKED, WE ANSWERED! A self-paced, lower-priced course with the same high-quality horticultural instruction as the instructor-led winter course.  The course is now open and you can register until September 1st. After that, it will be closed until Summer 2025.

The Art and Science of Caring for Plants

Grow your gardening knowledge, whether you’re a beginner or an experienced gardener. If you’re looking for a comprehensive, science-based, horticulture and gardening essentials course, our Home Horticulture Certificate could be for you! 

Drawn from the training Oregon Master Gardeners receive, this on-demand summer course provides the same training as our popular instructor-led Certificate of Home Horticulture course. Both offer an exceptional experience that will help your garden thrive. (The instructor-led course will be offered again in winter 2025.)

NOTE: Though this course duplicates some of the training Oregon Master Gardener volunteers receive, this Certificate of Home Horticulture class will not lead to Master Gardener Certification.

Home Horticulture Overview

The 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.

During the course, you will learn about:

  • Basics of botany and entomology
  • Integrated Pest Management and pesticide safety
  • Diagnosis and prevention of plant problems using least-toxic methods
  • Soils, fertilizers and composting
  • Ornamental, herbaceous plants and woody plants
  • Vegetable and container gardening
  • Sustainable landscape design and maintenance

Certificate of Home Horticulture

Upon completion of this self-paced summer course, you will receive a Certificate of Home Horticulture. The curriculum for the online Home Horticulture course includes an innovative online format that includes:

  • 16 recorded lectures on a variety of Horticulture subjects you can use in your garden
  • Assignments you can do where you live. Many are hands-on and will deepen your understanding of the material.
  • Subject quizzes to help you retain information
  • Extensive additional resources to help ensure your long-term success

Upon successful completion of the online course, you will receive a digital Certificate of Home Horticulture.

NOTE: Though this course duplicates some of the training Oregon Master Gardener volunteers receive, this Certificate of Home Horticulture class will not lead to Master Gardener Certification.

Open Registration

This program is open to all. You don't have to be an OSU student or even live in Oregon.

Many of the modules, such as Botany Basics, Soils and Fertilizers, Intro to Entomology, Pesticide Safety and more are applicable anywhere. Others that are more plant-oriented use mostly western Oregon examples, although there is still plenty of basic, essential information. Western Oregon is a temperate, zone 8, dry-summer, wet-winter region. We include some information for dryer regions such as central Oregon as well.

If you live in a climate that is extremely different from western Oregon, most of the topics will still be useful, but you are encouraged to supplement the course with local information as well.

September 30 - December 8, 2024
Question: What technology is needed? ~ Kim W.
Answer: For the Home Horticulture online program, a computer and access to the internet are needed to take the course. You could rely on a tablet or iPad, however, the program is designed for the best experience using a computer, so a tablet is not optimal.
Question: Are there required reading for the online home hort gardening class?
Answer: There is no required text book, but there is a suggested book from the  OSU Extension Service Publications Catalog called  Sustainable Gardening. This book is the source for many of the readings for each subject, and contains additional topics that are not covered in this class. 
Question: I'm a Canadian Citizen, just want to make sure I am eligible to take this course. ~ Julia R.
Answer: Yep, you are eligible! The online Home Horticulture is open to anyone. There are no prerequisites or restrictions. 
Question: What if I can't finish the MG course in time? ~ Rita G.
Answer: You will have access to the Home Horticulture course for one month after the end date.
Question: How is this program different from the Master Gardener program? ~ Caroline R.
Answer: The Certificate of Home Horticulture has all the same online course content, but unlike the Master Gardener Certification, the Home Horticulture program does not require volunteer hours and therefore does not result in a Master Gardener Certification.  
Question: Will there be tests given throughout this gardening class? ~ Kim W.
Answer: Yes, in this online gardening and home horticulture course, there are weekly quizzes and assignments. You'll have a chance to show how much you've learned with a final exam at the end. Everything is graded as pass/fail and if you pass, you will receive a certificate of completion.
Question: When is the cut off for enrolling in this gardening training course? ~ W.K
Answer: Due to its popularity, enrollment for Home Horticulture is held open through the first week of class.
Question: Regarding the Certificate of Home Horticulture.... About how much of a time commitment is the program (per week)? And also, is there anything that's scheduled? Or are all of the lectures recorded, with intent that we watch them asynchronously? ~ Kate D.
Answer: To get the most out of this online Home Horticulture course, it is suggested that you spend about 6 – 9 hours a week on it. The class is asynchronous so there is no set time you have to be online. So you can attend classes when it's most convenient for you. However, quizzes and assignments will have a specific date, but you can choose where and when you work on them. 
Question: Do you have to be located in Oregon? ~ Nicole W.
Answer: Nope, there is no geographic restriction. You can take this online course anywhere there's an internet connection. 😀
Question: Is this course info specific to plants in the Oregon climate/planting zone? Or is it more general plant info that anyone can use regardless of what climate they live in? I live on the east coast and would love to sign up for this. ~ Megan T.
Answer: Many of the modules, such as Botany Basics, Soils and Compost, Intro to Entomology, Pesticide Safety, and the like, are applicable anywhere. Others that are more plant-oriented use mostly western Oregon examples, although there is still plenty of basic, generalized information. We include some information for the dryer regions of the PNW west, too. People in climates that are extremely different from western Oregon - desert or tropics - should plan to supplement the course with local information as well, especially when it comes to specific plants that will do well in their region, and special gardening techniques and timings that are specific to their climate. 
Question: I see there is a non-refundable $60 fee, is there a time constraint on withdrawal from the course and will there be financial penalties beyond the non-refundable fee? ~ Margaret B.

“I took the Home Horticulture Intensive course to expand my knowledge of my favorite hobby, but now it has evolved into a small business.”
Chelsae Marsh

I wanted to learn more about the science behind plants. I also wanted to validate my pre-existing knowledge of horticulture and desired a defined certificate that I could present to a future employer. I learned more information, gained quality written readings in the form of pdf downloads, and received a certificate for my resume. And the online flexibility, and the readings were all really easy to read and full of important information.

Jake Cardoza

This program taught me how to correctly manage my plants and any pest/disease they have. I was concerned about the pace of the class as it was accelerated, but did not find it to be too fast. I enjoyed the online flexibility and ability to look through quizzes at a later date. It was very instructive and just challenging enough to really teach students.

Keira Hedges

"Thank you to all of the instructors for providing such a wonderful course. I thoroughly enjoyed this course and would highly recommend it to anyone that has an interest in Horticulture."

F. S.

“I learned so much in the Home Horticulture Summer Intensive class that I took. My house plants have never been happier, and it even motivated me to begin certification with the Backyard Habitat Program. I would recommend the class to everyone."
