Transform your patchy, yellowing St. Augustine lawn into a vibrant, envy-worthy green carpet with the right fertilizer. St. Augustine grass, a warm-season favorite, demands specific nutrients to thrive, but choosing the wrong product can lead to weak growth, weeds, or even lawn burn. That’s why we’ve compiled this comprehensive guide to the best 10 St. Augustine fertilizers available on Amazon in 2025. Backed by customer reviews, expert insights, and agronomic data, our recommendations will help you make an informed choice to achieve a lush, healthy lawn that stands out in any neighborhood.
Why St. Augustine Grass Needs Specialized Fertilizers
St. Augustine grass (Stenotaphrum secundatum) is prized for its thick, carpet-like texture and vibrant blue-green hue, making it a top choice for lawns in warm, coastal regions like Florida, Texas, and the Gulf states (USDA zones 8–10). Its coarse blades and shade tolerance set it apart, but it requires a precise nutrient balance to maintain its vigor. High nitrogen fuels lush foliage, phosphorus supports root development, and potassium enhances drought and disease resistance. Micronutrients like iron prevent chlorosis (yellowing), a common issue in sandy soils.
Without proper fertilization, St. Augustine lawns can suffer from thinning, weed invasions, or pest issues like chinch bugs. Over-fertilizing risks burning the grass, while under-fertilizing leads to sparse growth. Experts recommend a 3-1-2 or 4-1-2 N-P-K ratio and fertilizing every 6–8 weeks during the growing season (spring through early fall). Soil testing can pinpoint deficiencies, ensuring your lawn gets exactly what it needs for optimal health.

Key Considerations:
- N-P-K Ratio: St. Augustine thrives on high-nitrogen (3-1-2 or 4-1-2) formulas with moderate potassium and low phosphorus. Iron is crucial for preventing chlorosis.
- Granular vs. Liquid: Granular fertilizers offer long-lasting feeding but require spreaders; liquid fertilizers provide quick results and easy application.

- Coverage Area and Cost: Calculate cost per square foot to ensure value, especially for large lawns (e.g., Lesco’s 10,000 sq. ft. coverage).
- Additional Features: Look for iron for greening, weed control (BioAdvanced), or slow-release formulas for low maintenance.
Seasonal Application Tips:
- Spring: Use high-nitrogen fertilizers like GreenView or Scotts for rapid green-up.
- Summer: Opt for slow-release formulas like The Andersons or Pennington to sustain growth in heat.
- Fall: Choose potassium-rich options like Espoma to strengthen roots for winter.
Common Mistakes to Avoid:
- Over-fertilizing, which can burn grass or harm waterways.
- Ignoring soil tests, which reveal nutrient deficiencies (e.g., iron or pH imbalances).
- Applying during drought or extreme heat, which stresses St. Augustine.
Additional Features: Consider fertilizers with iron (Lesco, Pennington) for color, micronutrients (Simple Lawn Solutions) for overall health, or weed control (BioAdvanced) for multi-tasking.
Maintenance Tips for a Thriving St. Augustine Lawn

- Mowing: Maintain St. Augustine at 3–4 inches to enhance shade tolerance and reduce stress. Use sharp blades to prevent tearing.
- Soil Testing: Conduct annual soil tests to monitor pH (ideal: 6.0–7.0) and nutrient levels, addressing deficiencies with targeted fertilizers.
- Aeration: Aerate annually to reduce thatch buildup and improve nutrient and water uptake, especially in compacted soils.
