Well. I live in the south and the government (and private property owners) very aggressively spray and uproot kudzu. I always figured the slowed spread had more to do with that.

It is remarkable how fast it grows - there's a certain spot here where you can almost watch it grow up and over and on the powerlines in a very short span of time, until it is sprayed back and does it all over again.
