Signs of Over Watering 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.
