kudzu is an irreversible misery, that stuff can grow 1-2 feet per day and will choke out EVERYTHING. The only thing that I would use kudzu for is for landscape revenge on someone you don't like. BSK, do you know where I can get some kudzu seed.
Seriously, it was first used by CCC 1930s(I think) for cover management practices to reduce erosion and stabilization of soft road cuts. Now it's a menace. I don't know how it escapes any government eradication efforts with regards to it being an invasive species, they may have just wrote it off.
