St. Augustine Lawn Fertilizer Services

We recommend waiting a week after weed control to fertilize your lawn. It’s best to fertilize the soil when it’s not under any stress from weed control. Similarly, you should wait a few days before fertilization after treating the lawn for pests. However, there are fertilizers that include weed control and work well together. Our team will work closely with you to help you determine the best course of action for your lawn.

For a healthy, dense growth and vibrant appearance for St. Augustine grass, you should always consider fertilizers that provide a balanced mix of micronutrients, particularly nitrogen, phosphorus, and potassium. Let's take a look at some of the best lawn fertilizers for St. Augustine grass types:

• Hi-Yield 4# Ammonium Sulfate: This type of fertilizer contains 21% nitrogen and 24% sulfur, which helps in boosting the growth and the thickness of your grass. The sulfur also aids in soil pH balance and nutrient uptake.
• The Andersons PGF Complete 16-4-8 Fertilizer: This is a very well-balanced fertilizer for St. Augustine grass. It has an NPK ratio of 16-4-8, which promotes healthy root development of the root system, and increases tolerance to heat, cold, and drought. It even increases your lawn's ability to withstand pests and diseases.
• Polymer-Coated Urea: This is a slow-release fertilizer with 40% nitrogen, which is gradually supplied to the lawn for over 2–6 months. This will reduce the amount of fertilizer applications and will minimize nutrient leaching, ensuring a continuous and balanced growth.
• Down to Earth Bio-Turf 8-3-5 Fertilizer: This is an OMRI-certified organic fertilizer that has an NPK ratio of 8-3-5 and will strengthen the turfgrass's tolerance to heat, cold, and drought. It will encourage strong root growth, and will provide a steady supply of nutrients to the grass over an 8-week period.

While you can certainly fertilize your St. Augustine grass during the winter, it does require careful consideration to avoid damaging your lawn. Let's take a look at some key points to consider for the best practices for St. Augustine lawn fertilizer in the winter:

• Avoid high-nutrient fertilizers: During the winter, you should avoid high nitrogen fertilizers, since they often encourage new growth that may be vulnerable to cold damage. Instead, choose fertilizers that promote healthy root growth and energy storage without stimulating excessive growth.
• Use slow-release or high-potassium fertilizers: Slow-releasing fertilizer with a high potassium content is recommended for winter application. This will help the grass store energy for the upcoming growing season, and even enhance its resilience to the cold and disease.
• Timing of application: You should strive to apply fertilizer in the early fall before the winter settles in. This will ensure that the grass has the necessary nutrients to sustain it through the colder months without promoting new growth.
• Soil conditions and pH: If necessary, you can adjust the pH of your soil using lime or sulfur, but avoid applying these during the active growth season. The optimal range of pH for St. Augustine grass typically requires a number between 6 and 6.5.
