Kudzu is listed in Chinese medicine as one of their top 50 sacred plants. However, I think they had specific rules (and may still have those rules and practices today) in China that kept it under control. I live in the PNWet, so my climate is very different. Many plants that are invasive in the SE, like autumn olive, are just fine here. We have long, dry, hot summers that are very different from those in the SE and E USA, and long, wet, cool, drizzly winters.
I would love to grow kudzu, but I would start in a container. If I were to grow it in the ground, I would take a hint from our equivalent: bamboo. It is extremely invasive here, especially the tall kinds that grow in sun. If you grow bamboo here, you need to put in a barrier all around the plant. There are commercial barriers that they sell exactly for this. Bamboo nurseries, which exist here, will only sell you the bamboo if you explain exactly what your plan is to stop its invasiveness. Some will plant it in an area surrounded by cement barriers. That's ok too.
I am excited to hear about these experiments.
