While I’m sure that other people have already written about this incredible invasion of unpleasant plant life, I think it’s important to emphasize that this is a huge problem sweeping the Southern USA. As soon as we began discussing invasive species during class, this was the first thing I thought of. In North Carolina you can hardly walk a few steps without seeing some amount of kudzu growth. While I was already aware of the kudzu mythos, I didn’t understand how it choked the land and prevented forest expansion until about a year ago. Like the Dust Bowl, the emergence of kudzu is an event that was perpetuated by human greed and spiraled out of our control before we could begin taking preventative measures.

Kudzu is originally from various areas of Asia, including Korea, Japan, and China. It was introduced in the US during the Centennial Exposition in Philadelphia, Pennsylvania during 1876. It was meant to be an ornamental plant, and could provide shade when planted on porches and around trees. During the 1940’s, however, one very vocal advocate of kudzu claimed that the plant prevented erosion and even created clubs in the name of planting more and more kudzu across the South. This backfired when the vine started choking native vegetation and the US Government discouraged planting kudzu in 1953. Up until that point, they were paying farmers up to eight dollars to plant the stuff during the Great Depression.
Not only is kudzu everywhere, it’s also almost impossible to kill. Even with the right herbicides, the plant can take from four to ten years to die, and that means a lot of time for more kudzu to spawn. Not only that, but because it covers forests completely native trees don’t get enough sunlight and die off as a result. Kudzu growth is currently outpacing our attempts to contain it to an incredible extent, and there is very little we can do aside from use the vine for things like basket weaving, and maybe turn it into face creams, jellies, lip balm, and any other manner of products. No, really.
Kudzilla
Unfortunately, the spread of kudzu is just one example of a phenomenon that happens over and over again in American culture, especially when natural resources are involved. When farmers discovered that by turning over the topsoil and planting huge fields of corn they could produce an even larger harvest in record time, companies started to manufacture bigger, more powerful equipment so that the land could be torn up and the topography changed in just a few years. As soon as the dust storms that had previously only been a nuisance started up again, however, there was no topsoil to protect the layer of dirt below and all of that loose material was swept up by the wind. This resulted in intense dust storms that lasted almost ten years and put a huge amount of Midwestern farmers in debt.
Discovering something positive and then exploiting that positive until it becomes a negative is almost a cultural tradition. Hopefully, we’ve learned our lesson from invasive plants like kudzu and can avoid going down this path again and again.
