Master Gardener Logo

The Master Gardener Program was originally created by the Extension Service of Washington State in 1972. It grew out of the need to meet increased requests from urban home gardeners for horticultural information. Before the program was started Extension Agents were dealing mainly with farmers and ranchers. Because of the urban and transient nature of the modern American life they also became a resource for answering urban landscape and garden questions, including insect and disease control, plant culture and variety selection. The Master Gardener is a vital part of Extension's ability to provide the community with up-to-date, reliable knowledge so they can enjoy and protect the value of horticulture around their homes. 

How Does The Program Work?

Master Gardener courses are offered in a self-paced, self-study format. Online instruction is provided by Montana State University-Bozeman Extension Master Gardener Coordinators, utilizing the Academic Technology & Outreach (ATO) Brightspace platform. There is no time limit for completing each course.

Volunteer Commitment

In order to be certified and maintain good standing as a Master Gardener, participants agree to complete a minimiun of 20 hours (for Level 1), 30 hours (for Level 2), and 40 hours (for Level 3) of volunteer service through the Yellowstone County Extension Office. Volunteer opportunities include: working in a neighborhood garden, giving gardening presentations at schools and to civic groups, manning Info-Booths, telephone and office work, researching and writing grants, fair judging, fund raising, land research, and other opportunities as they present themselves.
