I planted three mounds of 'three sisters' this year and as things started to grow, everything looked real good. Then the winter squash took over. These things are as big as my pumpkin plants, and sprawling just as long. I can't believe how big these plants have gotten. They're supposed to be a ground cover between the mounds, and now they're covering half the garden. I'm ready to get the hoe's out and start cutting.
