Master Gardeners

What is a Master Gardener?

The program is open to any adult with an interest in plants and a desire to share that with others. Master Gardeners are a dedicated group, and many choose to return year after year to share their knowledge with others. The University of Illinois Extension Master Gardener program is for enthusiastic individuals who have completed training and agree to volunteer at least 40 hours within two years at their local University of Illinois Extension office.

Certified Master Gardeners educate the public on topics such as improving landscapes, choosing plant varieties, water-saving tips, gardening tips, proper pest identification and management, growing their own produce, optimal mulching strategies, and composting. The only guideline is that the projects be educational and concern horticulture. You will work with the local Extension Unit Leaders to determine how your volunteer time can best be spent.
