Best Online Master Gardener Programs of 2023

Online master gardener programs allow budding horticulturalists to learn more about plants and gardening. They can also provide certification which can be useful to those who wish to benefit their community in broader ways. Becoming a master gardener, or just taking a course on gardening online, can help you learn and grow as a gardener.

Consider what you wish to achieve from the program: You may simply want to improve your skills and tend your own garden, but if you are interested in certification, there are additional factors to bear in mind.

Certification as a master gardener usually involves contacting the local university co-operative extension in your particular area. It is state or country-specific and usually involves a course, which can be online or in person. Also, logging a certain number of volunteer hours is also required in order to achieve certification.

How to Choose the Best Online Master Gardener Programs

Above, we have outlined some options to consider. But there are many master gardener programs out there. Whenever you are evaluating options and trying to find the best online master gardener program, you should consider cost and value, what the program specializes in, level and experience, the duration of the course, format, and what types of certifications are available.

Online Master Gardener Programs vs. In-Person Instruction

Format is perhaps one of the most important things to consider when choosing an online master gardener program.

Whether an exclusively online program or in-person instruction is right for you will depend on what exactly you hope to gain from the course. It will also depend on what type of learner you are. Some people can successfully learn remotely. But others find it much easier to learn while going through the motions and being face-to-face with instructors.

If you prefer face-to-face instruction then you should certainly contact your local university extension to find out about courses, volunteer hours, and becoming a master gardener in your area. If you opt for online though, you can apply what you're learning directly into your own garden.
