Does this look like insect damage to grass?
I posted a message earlier, but now am thinking that this might be insect damage. We found wireworms in the backyard several months ago, and just now we found a single wireworm in a small patch we dug up in one of the yellowing areas in this photo.
This is St Augustine. We have not put fertilizer down yet. We were about to put nitrogen down at the direction of the Clemson Extension office per the soil test.
Suggestions on what is causing this grass death?
