How do you get rid of kudzu?

With difficulty. Kudzu, also known as the mile-a-minute vine, is tenacious. To eradicate it, you must destroy the root system, which is not easy. The primary root can extend 7 feet or more and weigh as much as 440 pounds. The roots also can grow as deep as 20 feet. Herbicides usually don’t work because the hairy vine can provide a waist-high protective mat.
