Symptoms: Patch diseases can be caused by fungi, appearing as brown circles with a green patch in the center. It is commonly said to look like “frog’s eye”. Once established, these can be very difficult to control.
Conditions: The conditions that favor patch diseases are excessive thatch, high humidity, and high tempuratures.
Recommended Treatment: Fungicide treatments are recommended to slow down and possibly stop the spread of these diseases. Core aerations are also helpful. In severe cases, a second fungicide treatment may be necessary.
The areas with the rings will need to be reseeded. The grass will not come back on it’s own.
We also recommend using proper watering and mowing practices.
