Become a Master Gardener

Master Gardeners are members of the local community who are interested in gardening and the environment. They participate in an extensive training program and commit to completing a certain number of volunteer hours on horticulture-related community projects each year. Master Gardeners are organized by their local county Extension unit. Upcoming face-to-face training will take place on Thursdays, January 24 - April 10, 2013.

The cost for the training is $175 and includes a comprehensive horticulture textbook. Classes take place on Thursdays from 9:00 a.m.–3:30 p.m. at the Knox County Extension Office in Galesburg.

The classes are taught by University of Illinois Extension educators.

Master Gardener volunteers work on behalf and under the supervision of University of Illinois Extension. The volunteer work is conducted in the local Extension unit and throughout the community on various projects involving parks, schools, gardening, or other city agencies.

Certified Master Gardeners are those who have completed their training and internship.

To remain active, certified Master Gardeners must complete 30 hours of volunteer service and 10 hours of educational training yearly. These are reported to and recorded by University of Illinois Extension.
