Lawn Care: 4 Signs You Are Overwatering Your St. Augustine Grass

St. Augustine is a wide-bladed, warm-weather, grass that does well in Florida. It grows quickly in summer and slows down during winter, when less watering is needed. Too little water can damage this species, but too much can also lead to lawn care problems because St. Augustine has shallow roots and is vulnerable to fungal attacks.

Look out for the following signs of overwatering:

  1. Depressions: If you walk on your lawn and the grass leaves don’t spring back, this is often a symptom of overwatering. Your footprints will leave matted depressions.
  2. Curled Leaves: When the leaves show signs of curling, it’s usually because they have had too much water. This is a lawn care mistake that many people make. Don’t water again until the leaves have straightened out.
  3. Dying Grass: Overwatered St. Augustine grass is at risk of being attacked by a fungus called ‘brown patch’. When the lawn starts dying, brown circles appear in multiple patches, like this:

  4. Change in Color: Overwatered St. Augustine often changes in color. The blades take on a grayish-blue hue, instead of a deep green.


What about St. Augustine grass and weeds? Several weeds can affect it, including crabgrass, annual bluegrass, fescue, clover, chickweed, henbit, dollarweed and goosegrass. These weeds not only rob the grass of nutrients, but they can completely take over areas of a lawn. If your St. Augustine grass is being invaded by weeds, consult with a professional lawn care company and ask for a free estimate to have the problem resolved.
