I live in southwest Florida and almost overnight parts of my lawn have turned completely yellow. We have had unusual low temperatures. I do have a sprinkler system so I know the lawn has been watered. What should I do.
If you have zoysia grass, it is probably going dormant. In the north, zoysia is the first grass to go dormant in the fall and the last one to perk up in spring. I think you'll see it recover when temps return to normal.
