There are three parts to becoming and staying a Certified Master Gardener: 1) attending the training, which provides novice and experienced gardeners alike with the opportunity to improve their horticultural knowledge and skills, and 2) sharing at least 25 hours of expertise and time with the public through organized volunteer activities, and 3) earning at least 12 hours of personal continuing education.
If you are interested in learning more about the Master Gardener program or applying for the upcoming class, please visit the "How do I become a Master Gardener?" page.
