Missouri Master Gardener Core Manual coverEditor’s note
The following abstract describes a publication that is only available for purchase. Links to the individual chapters are provided below.

The Missouri Master Gardener program provides in-depth horticultural training to individuals throughout Missouri who then volunteer their time applying what they have learned to help others in their communities to learn about gardening and environmental education. The program’s core manual contains 14 guides: 13 detailed guides on a variety of horticultural topics and one covering program policies.

To become a Missouri Master Gardener, an individual must first attend a 30-hour classroom core course training. Then the Master Gardener trainee is required to give 30 hours of volunteer service back to their community in approved University of Missouri Extension activities, thus fulfilling the program’s mission of “helping others learn to grow.” Master Gardener training is offered online and face-to-face or combination.
