This invasive vine swallows a flower bed area at a clients house of mine. It seems every 2-3 weeks they call me and want me to come pull more weeds. Their backyard is downhill from a overgrown wooden area. The beds are about 160 sq ft long and I fill up 2 large trash bags each time I go weed for them. It's all mainly this weed. They are hard to pull out of the ground and have a very thick root.
