Title: Brown patches on St. Augustine grass
Answered by: Nan Hampton

QUESTION:

I have brown patches on my st. augustine grass, it looks like the grass has rotted from standing water, but the drainage is not a problem, What could it be?

ANSWER:

There are several possibilities for the cause of the brown patches on your Stenotaphrum secundatum (St. Augustine grass):

1) Fungal disease such as brown patch or take-all patch;

2) Insect pests such as chinch bugs or grubs; or

3)  Drought.

Please see the City of Austin's Grow Green Earth-Wise Guide to Lawn Problems for diagnoses, detailed descriptions and treatments.
