I am puzzled about why my pond has essentially no vegetation. I've pulled in only one water weed while fishing, and I've drug many lures and flies across the bottom. It was one of the several kinds of common water weeds (Potamogeton or Najas), and it was in bad shape. I put it in an aquarium to see if it would grow a new leaf or two so that I could identify it better, but it died. I wonder if someone put weed killer or grass carp in the pond. In either case, I may have wasted my time and money planting the gorilla grass.
