We need help with our lawn!
Late last year (November), we had St. Augustine sod planted. We followed our landscaper's instructions with initial care (i.e., frequent and long watering, minimal foot traffic, etc.) for the first month. After the initial care, the lawn was fine up until a month ago when brown spots began appearing. At first, they were small and in isolated areas of the lawn. But after they began growing and spreading, we brought a sample and photos to our local nursery for advice. They suspected a fungus infection and advised us to cut back watering to twice a week for twenty minutes and to apply a fungicide. That was a month ago. The brown spots are still spreading and we're concerned that our grass is dying.
Additional environmental background:
We're in Southern California about 20 minutes from the coast. Temperatures are moderate.
Any assistance, suggestions or help would be appreciated.
