St. Augustine grass offers a plush green carpet for play and, if cared for properly, is a dense lawn that will keep out weeds. If you are thinking of growing the grass, make sure you are in a location where the climate is appropriate. St. Augustine is mainly grown in warmer climates, such as the southern and southwestern United States. St. Augustine grass has a height range from which to choose, depending on how much time you have to spend on your lawn.
Decide on the length of your St. Augustine grass. You can mow this grass at varying lengths from 1 1/2 inches up to 3 inches. Base your decision on length on the amount of time you want to spend taking care of the lawn. Cut grass 3 inches high every two weeks; cut 2 1/2 inch length every week to 10 days; and mow a lawn 2 inches or less every five days.
Adjust the blade height of the mower to the length you have decided on. If you have a mostly shady lawn, choose 3 inches.
Cut grass 1 inch higher in the fall. Raise the blade on the mower to adjust for this. Mow less often in the fall, as the grass grows more slowly.
