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?
Participants attend a series of classes that train them in the latest, research-based, home horticulture practices. There is approximately 32 hours of class time over a sixteen week period. There is a $125 fee for the Level 1 program (which includes the Montana Master Gardener handbook), and a $125 fee for the Level 2 program.

Volunteer Commitment
When you enter the Master Gardener Program, you agree that in return for the training you receive, you will volunteer 20 hours (for Level 1) or 30 hours (for Level 2 - 50 hours total if both Level 1 & 2 are taken) of service time through the Yellowstone County Extension Office. (The volunteer commitment for renewal after first year of training is 20 hours.)
Placement is based on your knowledge, skills and interests.

Master Gardeners are required to donate 20 hours of volunteer service a year, to maintain their Master Gardener status. Volunteer opportunities include: working in the neighborhood garden, giving garden talks to schools, manning Info-Booths, telephone and office work, presenting gardening topics to civic groups, researching and writing grants, fair judging, fund raising, land research, and other opportunities as they present themselves.
