St. Augustinegrass is a warm-season, perennial grass that is used in residential landscaping to provide a thick, dark green lawn. St. Augustinegrass thrives in sunny areas, and the wide blades hold up well to kids and pets. St. Augustinegrass spreads by runners and rhizomes and has difficulty setting seed. Because of this, it is available commercially only as plugs, sprigs or sod.
Soak the bare spots with water if they have occurred due to dog urine. Allow the spot to dry, and repeat the soaking process two more times.
Water the planting area to a depth of 4 inches if you haven't done so. Allow the soil to drain.
Create holes that are 1 inch wider than the St. Augustinegrass plugs' rootballs. Place the plugs 12 to 18 inches apart. A bulb auger or dibble will help you easily create the holes.
Add plug fertilizer to the holes according to the rate suggested on the fertilizer package for the size of the holes.
Place the plugs into the holes, and pat soil around the roots.
Water the St. Augustinegrass plugs just enough to moisten them, and then soak them everyday until they have covered the bare spot.
