Become a Master Gardener

Master Gardeners are adults of all ages who love gardening and want to share their knowledge and enthusiasm with people in their neighborhoods, schools, parks and communities. You can become a Master Gardener by taking the training course coordinated by University of Missouri Extension and the Missouri Botanical Garden. The course is held from January through May on Thursday afternoons or evenings at the Kemper Center on the Missouri Botanical Garden grounds. 

Our training classes cover a variety of horticultural topics. Missouri Botanical Garden staff, University of Missouri Extension faculty and qualified professionals in our community teach classes in the following topics.

  1. Plant Relationships, Anatomy, Growth & Development
    Soils, Composting & Mulching
    Propagation Techniques
    Lawn Care
    Flower Gardening
    Woody Ornamentals
    Native Plants
    Landscape & Garden Design
    Integrated Pest Management

Each person accepted into the Master Gardener program agrees to give 40 hours of volunteer work and acquire 10 hours of continuing education in one calendar year. There are a lot of opportunities for each throughout the year. The same 40 and 10 are required to keep certification active on an annual basis.

The 2015 class will begin in January. The fee to attend will be $335. Applicants should understand that a lot of studying will be required to pass the course. Students report an average of 10 hours outside of class per week. In addition, students will need to have access to a computer to communicate with the instructors and take one test online each week. An additional test each week is taken in the classroom. Students are expected to arrive on time and attend all 19 sessions. 

There will be two separate class options in 2015

  • Afternoon sessions from 1 to 4 p.m.
  • Evening sessions from 6 to 9 p.m.
