Many Pinellas homeowners are curious to learn how to care for St. Augustine grass. First, you want to check underneath the grass blades each spring for any thatch (organic matter that has not become fully integrated into the soil). If there is any more than a half-inch of thatch, rake the grass intensely. However, if the grass is still in its dormancy or if the soil is wet, do NOT dethatch. Give the grass regular mowing –specifically so that you do not get into a position in which you need to remove a significant portion of the blades in a single cutting. Otherwise, the growth rate of the grass (given specifics of the setting) will guide proper intervals for mowing.
In the absence of regular rainfall, St. Augustine grass should get about an inch of water per application. One way to easily check how much you are watering is to put a can out with the sprinklers running, to catch its water.
