Become a Master Gardener

The St. Louis area Master Gardener volunteer training program is the result of a partnership between University of Missouri Extension and the Missouri Botanical Garden. Those who complete the course become certified Master Gardeners after they complete 40 volunteer hours at sites associated with the Missouri Botanical Garden, other horticulture organizations, and the communities where they live. Trainees are supported by MBG staff while volunteering at Garden sites and by MU Extension while working elsewhere in the community. 10 hours of continuing education are also required to become a certified Master Gardener. These requirements must be renewed annualy to maintian active Master Gardener status.

  • Plant Relationships, Anatomy, Growth & Development
  • Soils, Composting & Mulching
