Duckweed is lighter green, grass green in color These
tiny green leaves float on top of the water. It is an
excellent natural food for pond fish. Each plant is
smaller than the eraser on a number 2 pencil. Duckweed
is the smallest plant in the plant species world!
most do not grow duckweed in the pond but grow it
outside of the pond in large containers to grow to feed
it to their fish. If you have a skimmer this plants
will very likely end up in the skimmer unless you have
fish that eat it quickly. My own guys get 3 pounds a
few times a week.
