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.
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.
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.
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. I hope to see more young people and will encourage others to try this program.
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.
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.
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.
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.
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!
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.
I am still having a great time reviewing all the lectures as this is all new to me and a great challenge to learn. I especially want to thank Signe Dangler for her lectures that I loved. They are so easy to listen to. Her comments to all of us on our assignments are so informative. I am amazed that she is so good and that she is so thorough to read through all the assignments and provide specific feedback. All the knowledge that she has repeated to her in the small assignment efforts that we present to her could be so boring and frustrating. The way she corrects them in such a friendly personalized way makes us feel as if a dear friend guided and corrected us in a positive discussion.
Signe Danler is a veteran Master Gardener and landscape designer with a Masters of Ag degree in Horticulture.
