Serving DuPage, Kane and Kendall Counties

Illinois Extension has a vast collection of resources addressing horticultural interests. We recognize that home and commercial horticulturalists each have unique needs, so we've cultivated a set of resources designed to address their top concerns. Check them out at the bottom of this page.

You also can contact one of our Master Gardener Help Desks or educators with your questions. Each county's Help Desk information and hours are available just below.
