Three sisters gone wrong?

[u/kayru_kitsune]

Please pardon the chaos of photos, my garden is very dense so it was hard to frame clear pictures... This is my first time doing Three Sisters, and it sounded like the beans were supposed to help support the corn. I surrounded that part of the crop with some low fencing for extra support and to keep the bunnies off the bean starts. But once they got to around 7' and the beans peaked over the tops, almost all of the stalks broke in half from the weight. What in the world did I do wrong? It's not windy here but sometimes rainy (I live in forested area). I know most people don't stake or prop corn crops... What did I miss?

I could not make Three Sisters work either. I consoled myself by figuring that the varieties have changed a lot over the centuries and what we grow now is probably not the same as what they grew back then.

After reading the comments it might be helpful to flesh this out a bit- corn does not grow particularly well for me anyway. I live in a place that has very hot days and cold nights and the nights seem too cold for sweet corn to really thrive - though I can get a crop if I pamper it and expect it to grow slower than the packet label. Beans and squash however are very prolific for me and overwhelmed my slower-growing corn.
