I have many darker green patches about 1 foot wide all over my back yard and
a few in my front. These patches have grass that looks healthy but it grows
much faster than the rest of my lawn. There is no dead grass or brown grass
just dark green patches that have seemed to multiply on my lawn. I first
thought this may be due to our new female retriever and the nitrogen in her
urine but I have also seen this in the front yard and on a boulavard down
the street. Any ideas?
