Kudzu was imported from SE Asia in the 1930's to use as erosion control especially along highways. It is a vine that grows 1' per day. It covers the ground, grows up telephone poles and can completely kill smaller trees by covering them up. It grows deep roots. To get rid of it you have to use cows or goats and graze it down to the vines, then put hogs in there to root up the root system. It is very hard to kill short of digging it up. You want me to send you a sprig? It really doesn't grow up north because cold kills it like a decidous tree. However it isn't cold enough long enough in the south to completely kill it off. It comes back in the spring. Honeysuckle vines were also brought from Asia for erosion control also. However, honeysuckle is well liked by bees and due to the sweet flowers. We used to break them off and suck out the sweet nectar in the flower. It doesn't grow as fast as kudzu.
