Q: can the black beauty seed be put down over an existing lawn?

As I mentioned in a previous review of this product the product didn't germinate(grow) in two attempts to overseed an existing lawn under ideal conditions. I even took some seed and placed it in a seedling tray and it didn't germinate either. I attempted to reach out to the company twice prior to posting the negative review to provide them with an opportunity for a response/explanation and never received a response.
