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 below.

Master Gardener Help Desks (in-person or via phone) are postponed currently. However, we're still here to help you grow! Each county's Help Desk email accounts are open!
