Buyer’s Guide to Fertilizing St. Augustinegrass

Choosing the right fertilizer for your St. Augustinegrass is essential. Here are a few key factors to consider:


A soil test can help determine your lawn’s specific nutrient needs. In general, St. Augustinegrass requires nitrogen for its green color and phosphorus for healthy root development. Potassium strengthens grass immunity. Look for fertilizers with NPK ratios like 4-1-2, 3-1-2, or 3-0-0.

Time of Year

Fertilize your St. Augustinegrass every 8-10 weeks during the spring and summer. Avoid fertilizing during winter, and never exceed recommended nitrogen amounts in a calendar year.

Type of Fertilizer

Choose between slow-release and quick-release fertilizers. Organic options yield long-lasting results, while synthetic options may be more affordable. Consider whether you prefer granular or liquid fertilizers.


The cost of fertilizing your lawn depends on its size and the type of fertilizer you choose. DIY fertilization typically costs between $40 and $320, while professional services range from $120 to $480 per fertilization.

With these tips in mind, you can confidently select the perfect fertilizer for your St. Augustinegrass lawn.
