What Makes Weeds Thrive in Illinois?

Weed Pressure by Region in Illinois
When you look at weed pressure in Illinois, you’ll notice distinct differences based on the region.
Northern areas are plagued by cold-hardy creepers and lawn chokers, while the central region faces challenges from shifting zone weeds.
In southern Illinois, you’ll find a mix of statewide spreaders that can quickly take over your garden or lawn.
