We installed about 1500 sq ft of Bermuda sod on top of 2” of compost this spring. We have been watering daily for the first 4 weeks as instructed and it was a deep green in color. Was looking great. We finally mowed and raked the lawn. After the 4th mowing it now looks like this! I have changed the water pattern to 3 times per week, 1/2” each watering. I’m in SC where it had been very hot the past few weeks. I thought it might be a fungus so I treated this past weekend. Any other ideas?
