2018 Master Gardener Course

The Master Gardener course is available every other year and alternates locations to serve Adams, Washington, Payette and Gem County. Applications for the 2018 Master Gardener Course will be available in fall of 2017. The course will begin the second week of January and will be 13 weeks long. If you are considering taking the course please contact us and let us know your preferred location and schedule. We will make a decision on the location and schedule in the fall.

Classes and Labs

UI Extension educators, specialists and other local horticulture experts teach Idaho Master Gardener classes and labs.

Field trips, readings from the Idaho Master Gardener Handbook and individual projects will fill out your instructional program. Some materials are also available in Spanish.


Once you have finished your classroom training, passed your exam and completed your volunteer hours, you’ll be certified as an Idaho Master Gardener.

As a certified Idaho Master Gardener, you’ll have:

  • Up-to-date basic gardening knowledge
  • Pest identification abilities
  • Leadership training
  • Service skills

Many Idaho Master Gardeners choose to extend their certification into future years through advanced training and a commitment of additional volunteer hours.

To remain current on certification, volunteers must attend at least eight hours of education and contribute eight hours of service annually.

Contact UI Extension, Washington County ( or 208-414-0415) for specific Idaho Master Gardener course information.
