sremick said:So I tried the "Three Sisters" method this year for the first time in one of my beds. I waited until the corn was at least 6" before planting the beans, as directed. However the beans are overwhelming the corn stalks, weighing them down and toppling them over. 
What did I do wrong? Not wait long enough before planting the beans? Wrong variety corn or beans?
I also had the same problem. At the community garden the beans took down the corn... and the squash was so shaded the insects and diseases could not be overcome. I harvested 1 zucchini and 2 ears of corn there. Then the big pile of bean vines made it impossible to harvest. Here at home I planted the half runner pinto beans on the corn and they were better, but still a big mess. The beans overcame the corn cobs, too, strangling them! The squash has finally taken off now that the corn and beans are done. It was not worth all of the work. I am sorry that you also tried this and had the same problems.
