The Best Way to Care for St. Augustinegrass in Florida

St. Augustinegrass is a popular choice for lawns in Florida due to its lush green appearance and tolerance of the state’s warm and humid climate. However, like any grass, it requires care to maintain its health and beauty. In this blog, we will discuss the essential St. Augustinegrass care practices that you should follow to keep your lawn looking great. 


Watering is a critical aspect of St. Augustinegrass care, especially during hot, dry periods. The grass needs approximately one inch of water per week, including rainfall. If your area does not receive ample rainfall, it’s important to supplement with regular irrigation. It’s best to water early in the morning before the heat of the day but with enough time for the water to evaporate from the leaf blades before nightfall. Avoid overwatering, as this can result in root rot and other issues. Use a rain gauge or a moisture meter to determine whether your lawn needs watering.

Mowing is another essential aspect of St. Augustinegrass care. The grass should be mowed regularly, being careful never to remove more than one-third of the total length of the grass in any one mowing event. Selecting a proper mowing height of around 3 inches is important to help the grass reach its full potential. Mowing too low can cause scalping and encourage weed invasion.

Fertilizing is essential for St. Augustiegrass to look its best, as it helps promote and improve the lawn’s overall health. It is recommended to fertilize three to four times per year, making sure only to apply fertilizer to actively growing grass. Products like 16-4-8, 15-0-15, and 28-0-0 will nicely complement a slow-release granular fertilizer program. Be careful not to over-fertilize as this can lead to pollution of water bodies. 

Weed Control

Weeds can be a problem in St. Augustinegrass lawns, and if left uncontrolled, can quickly take over. You can help prevent weed growth by maintaining proper mowing, watering, and fertilizing practices. Choose to manually remove weeds first before turning to herbicides. Using a preemergence herbicide in the fall and the spring can help limit weed encroachment.

Pest Control

St. Augustinegrass is susceptible to pests like chinch bugs, sod webworms, and armyworms. Regularly inspect your lawn for signs of pest infestation, such as yellowing patches or damaged grass blades. If you notice signs of infestation, treat them with an insecticide labeled for control of the specific pest. Again, be sure to read the label carefully and follow the instructions closely to avoid damaging your lawn or the environment.
