I have a few areas in my backyard that hold water just long enough to make the grass very thin/not grow but not long enough for the algae. I had a couple spots that were so compacted that they looked like this. You haven't spilt any chemicals have you?Stro3579 said:Im not a expert, but doesn't look like fungus. I am with cnet24 on possibly standing water, but if that was the issue, you would see black algae. Has this always been like this, or just occurred?
That side of the house gets the most shade and used to be pretty thin. But overall it has got better. These patches seem to SLOWLY be getting worse.Redtenchu said:I would do the screwdriver test first. The holes made will help a little if there is a drainage issue, but it looks to be sloped away from the foundation.
I have some areas around the north side of my house that are patchy like that because they don't get enough direct sunlight.
