How did Palmer amaranth and Waterhemp get in NC?

Depending on the species, weeds spread with the help of wind, water, or by other means. Additionally, people spread weeds with equipment, which is a very common way to spread weeds from field to field, across a state, from state to state, and even between countries. In this video, you will see how Palmer amaranth, a native species from the Sonoran Desert, traveled across the US and reached North Carolina. This video provides important information on prevention of weeds, including weed seeds traveling with farm products and used equipment.
