Interesting! I will plant some pumpkin seeds on the river bank into the knotweed patches and see, hope it is not a fluke. I know the area well as we walk the dogs regularly there. They spray roundup in late September every year but lots of them sprouting up in the spring like nothing happened, some looked stunted.
I give up the idea of growing asparagus at home after discovering harvesting knotweed shoots (away from sprayed patches) are way easier they are better tasting than asparagus, a small positive factor of such an invasive and expensive plant.
