My neighbor has a decent lawn with few weeds. The most original thing you notice are the white patches. There is a white leaf on each (stolon?) The grass looks like crabgrass. Together all the blades show up very noticeably. She has quite a few patches of it, though smaller in size. She has it along her sidewalk, and along the street. My best photo of it did not upload. I will look for or later take another. Can anyone figure out what caused it ? Or if there is a name for this condition? Thanks for any help.
