Because of sustained interest in our online Master Gardener online course (which is offered only in January), we now offer the same curriculum in an accelerated format! Upon completion of this course, you will receive a Certificate of Home Horticulture. Note: Our summer intensive program will not provide a pathway to Master Gardener certification. For certification, check out Option 1 of our January 2019 course.

If you’re looking for a comprehensive, science-based, basic horticulture and gardening course, our Home Horticulture Certificate could be for you! This expert-led course provides the same training as our popular Master Gardener Online program, which offers an exceptional experience that will help you make your garden thrive.

The curriculum includes an innovative online format that 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

We have traditionally offered this option alongside our Master Gardener Online program, which takes 12 weeks to complete. This new summer intensive version of the course allows you to gain the same training in a fraction of the time!

Course Description

The Master Gardener & 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.

  • 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
