Master Gardeners

Master Gardeners are volunteers who have received over 60 hours of training from Extension Educators and State Specialists from the University of Illinois.  They receive training in order to share unbiased, reliable, research-based information with home landscapers and gardeners. Another important function is to encourage young people to enjoy the pleasures of flower and vegetable growing.

The Master Gardener program is an all-volunteer program sanctioned by the land grant institution in each state and functions as an extension of the college or university. In Illinois, the program is sponsored by University of Illinois Extension.
