The University of Missouri Extension Center is offering its online Master Gardening course, beginning Aug. 23. 

The course will be taught by state horticulture specialists David Trinklein and Sarah Denkler. In a recent press release, Trinklein said the main goal of the course is to create initiative for service along with enriching community knowledge of plant life.

Participants work through 14 learning modules that cover topics such as basic botany, soils and plant nutrition, vegetable gardening, fruit production, landscape design, woody ornamental plants, turf management, insect and disease management, and pesticide safety. Overall objectives of the course are acquiring knowledge of plant growth and development, learning to apply this knowledge within a community, understanding basic horticulture terminology, and gaining an appreciation for what it means to be a Missouri Master Gardener.

To become a certified master gardener, participants must complete at least 30 volunteer hours and achieve a cumulative score of 70% or higher on chapter quizzes. Master Gardener coordinators will aid participants in finding volunteer opportunities in order to meet the hourly service requirement.

The deadline to register for the course is Aug. 13. Learn more and register at
