If you are interested in signing up for the next Master Gardener series, please contact the UI Extension, Teton County office. Depending on participant interest, we hope to offer this course every other year in our county (class size of 10 people minimum). If we do not have enough participant registrations, we offer the six-class High Altitude Victory Gardening series instead. This course is based on the Master Gardener curriculum, but in a condensed format without the volunteer requirements.
