I was finally able to figure out what kind of tree i have in my yard, that was there before i moved in. It is a Koelreuteria Paniculata or Goldenrain tree. It has these pods with little black seeds in them. They go all over my yard and make these sprouts everywhere. I can not cut it down because my neighbor has one just like across the fence line. I was just hoping to prevent them from growing. If there is a way to do it. If i could stop them I would have hardly any weeds in my yard and life would be great.
