Have you been noticing wilted circular patches that are brown or bronze in your lawn?
You might have take all root rot, a fungus that attacks St. Augustine, bermuda and centipede grasses.
To identify the disease, pull up a piece of the infected grass. If it is pulled up easily and has black, rotted roots , then Take all is your culprit.
Take All likes to attack in the fall and often goes undetected until early spring where noticible symptons appear, but at this point the damage has been done.
There is not much you can do for your lawn in the summertime just don't make it worse. Water deeply and infrequently as possible. Overwatering is often a cause of Take All. Make sure the pH is not too high, preferably between 5.5 and 6. If chemicals must be used then apply in fall or early spring .
