Master Gardeners

Who Are Master Gardeners?

Master Gardeners are a part of Cook County Extension’s Horticulture program and a vital link to getting research-based horticultural information to the public. They are volunteers who are passionate about gardening, plants, community, teaching, and the environment. Delivering horticultural education is what they’re all about! Master Gardeners have no products or services to sell; they can provide unbiased, research-based information from the University of Illinois to the public. They serve youth and adults of all ages and backgrounds through free or low-cost public programming.

Their mission is Helping Others Learn to Grow. Master Gardeners involve people in improving their quality of life by helping them find sound management practices for home and urban natural resources, by creating aesthetically pleasing environments, by promoting well-being through people-plant interactions, and by contributing to a safe, abundant food supply through home fruit and vegetable production.

There are three Master Gardener Programs for Cook County. These are Cook Chicago (within city limits), Cook North Suburban (north of Roosevelt Road), and Cook South Suburban (south of Roosevelt Road) units. Additionally, Chicago Botanic Garden runs a Master Gardener program. Master Gardeners must complete volunteering in the unit they apply.

What Do Master Gardeners Do?

To continue being certified active volunteers, MGs are required to volunteer a minimum of 20 hours each year and complete 10 hours of approved continuing education annually. Volunteers work in their communities teaching the public about horticulture topics. Please see the program request forms below to request programming!

Volunteers also run a year-round answer desk where you can ask your gardening questions.
