Signs of Over Watering St. Augustine Grass

By John Smith
Too much water can lead to  problems with St. Augustine grass.

St. Augustine is a warm-weather, wide-bladed grass commonly grown in the southeastern part of the country. St. Augustine grass grows rapidly in the heat and slows down in the winter, when less watering is required. A lack of water can damage this grass, but too much water can also produce problems because it is has shallow roots and is susceptible to fungal attacks.

Curled Leaves

If the leaves on St. Augustine grass begin to show a slight curling, it is a sign they probably have received too much water. Refrain from watering until the leaves straighten out.


When you walk on St. Augustine grass and the leaves do not spring back, it is often a sign of over watering. When this is the case, a matted depression will be left by your footprints.

Color Change

St. Augustine grass that has been over watered can often change color. Instead of a deep green color, the blades will have a more blue or grayish color.

Dying Grass

St. Augustine grass that has received too much water is vulnerable to being attacked by a fungus known as brown patch. When a St. Augustine lawn begins to die, brown circles will appear. These circles spread and usually multiple patches occur.
