Master Gardener Program
Jefferson County participates in the Colorado Master Gardener program. Citizens complete an application, are screened and interviewed in the fall. Those accepted into the program pay fees before Christmas, then begin the course of training in January. Basic classes (6 hours, once per week) are held in January and February, and a limited amount of supplemental classes are offered in March. The new Apprentice Colorado Master Gardeners then begin their volunteer work, consisting of 50 hours, with a certain amount of it performed in designated areas. All programs of the Colorado Master Gardeners in Jefferson County are designed to provide horticultural education to the public through a variety of venues including public speaking, media, and educational booths.
