St Augustine grass is a versatile grass that can adjust to different height requirements and conditions. Providing a lush green turf, it is a popular type for those who love to work and play in their yards. St. Augustine is not fond of cold weather and is mostly found in the southern and southwestern states in the U.S.
Decide how high you want your St. Augustine grass to be. Grass kept at a height of 2 inches or less must be mowed every five to seven days. Grass between 2 and 3 inches can last seven to 10 days, and 3 inches, 10 to 14 days.
Set the blades of the lawn mower to the height you want the lawn, based on how often you wish to mow.
Set blades to 3 inches for lawns that are mostly shady. St. Augustine does best at this height if it is in the shade.
Raise the height of the blade one inch from your normal mowing height during the fall. You will most likely not need to mow as often either.
