Are yellow patches in newly installed sod dead or a fungus?
Pallets of sod often arrive hot with fuzzy mold underneath from sitting stacked, but yellowing can also stem from heat stress or lawn disease. These damaged spots often recover if the underlying roots are still healthy, though severely rotted sections may need to be replaced. Proper watering and cooling help determine whether the grass will bounce back or needs to be rescued.

“My question is- do you think these yellow spots are dead dead? Im not sure how zoysia works- will the yellow spots die and the green parts fill in from the sides or is this a fungus- or are the yellow parts not fully dead and maybe come back pretty in the spring when its not 100°F?”source ↗
