The Idaho Master Gardener Program is an intensive 12-week course. It prepares you to help other gardeners with their gardening and horticultural problems.

Time Commitment

The Idaho Master Gardener Program requires:

36 hours classroom time (online)

From mid-January to mid-April. You will be given several open book quizzes and reading assignments.

40 hours hands-on training

Arranged with an Extension educator. Much of this time will be spent helping out in the Master Gardener room. There you will answer gardeners’ questions through the summer months with the assistance from an Advanced Idaho Master Gardener.

Certification and Credit

Upon completion of the course, master gardeners are considered paraprofessionals in home horticulture. University of Idaho credit is available for those interested.
