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.

2016 Master Gardener training program begins Feb. 23, 2016

Would you like to know what disease might be attacking your plants, what insect is destroying your favorite ornamental, how to grow vegetables for your family or what kind of trees are growing in your yard?  These are just a few things you could learn in a Master Gardener course.

The class sessions will be held on Tuesday and Thursday afternoons through the first part of April.  The deadline to register for the course is February 3. If you are interested in participating, please complete and return the application found here.

A person who wishes to become a Master Gardener is required to attend 30 hours of training, and agree to return 30 hours of volunteer service during the following year.  Enrollment is limited and there is a fee to cover the costs of the program and materials.

Jasper County University of Missouri Extension has conducted a Missouri Master Gardener program since 1992.  Trained Master Gardeners assist Extension specialists in providing unbiased educational information about various aspects of horticulture to the public.  Since 1992, over 470 people have taken the course here in Jasper County.  Several of these are very active in conducting community projects, providing educational programs and other horticultural/gardening activities.

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 consists of a minimum of ten, three-hour sessions over an approximate six week period. Topics usually covered include an orientation to the Master Gardener program, soils and plant nutrition, annuals and perennials, fruit crops for home production, insects, woody ornamentals, lawns and turf, vegetable production, diagnosing plant problems and trees in the landscape.

The chapter's annual plant sale is usually held in May.  Plants are sold at reasonable prices and include perennials, bedding plants, bulbs, trees, natives and other seasonal plants
