Master Gardener

The mission of the Missouri Master Gardener Extension Program is “helping others learn to grow.” The Master Gardener program provides in depth horticultural training to individuals throughout Missouri. They then volunteer their time applying what they have learned to help others in their communities learn about gardening and environmental education. The Master Gardener Program in Missouri promotes and raises public awareness of University of Missouri Extension as a source of unbiased, research-based gardening information.

Through activities such as Extension helplines, workshops, speaker’s bureaus, garden show booths and demonstration projects, Master Gardeners provide gardening information to thousands of Missourians each year.

Ozark Gateway chapter

In Jasper County, a participant must receive 30 hours of classroom instruction and agree to volunteer 30 hours back to the community. A participant must complete 20 hours of volunteer service, plus an additional six hours of continuing education yearly. The volunteer service has taken on many forms. Several have participated in community garden and community beautification projects. Some have given programs to various school groups, gardening clubs and residential care units. Others have provided assistance with a helpline in the University of Missouri Extension Center during the summer months. A fee is charged to cover the cost of the course core manual, handouts and other expenses. Other arrangements can be made if a participant does not wish to contribute volunteer hours.

The annual course covers a wide variety of topics including trees and shrubs, annuals and perennials, lawns, soils and fertility, pest management, control of invasive and noxious weeds and pests, fruits and vegetables, Season extension with cold frames, hoop houses and high tunnels will also be covered.
