Fertilizing St. Augustine: 5 Steps to a Lusher Lawn in 2023

If you're looking to transform your St. Augustine lawn from drab to dazzling, proper fertilization is the key. Follow our 5-step guide to give your lawn the nutrients it needs to thrive this year.

1. Determine Your Soil's Needs

The first step to effective fertilization is understanding your soil's nutritional profile. A soil test will reveal the levels of nitrogen (N), phosphorus (P), and potassium (K) in your soil. These essential nutrients play crucial roles:

• Nitrogen: Promotes lush leaf growth and greening
• Phosphorus: Supports root development and flowering
• Potassium: Enhances disease resistance and water uptake

2. Choose the Right Fertilizer

Once you have your soil test results, select a fertilizer that will address your lawn's specific needs. Look for formulations that provide a balanced ratio of N-P-K and include slow-release forms of nitrogen to prevent excessive growth.

3. Apply Fertilizer at the Right Time

The ideal time to fertilize St. Augustine grass is during its active growing season, which typically spans from spring to fall. Aim for the following application schedule:

• Spring: Apply a fertilizer with a higher nitrogen content to promote leaf growth.
• Summer: Use a balanced fertilizer that focuses on maintaining a lush appearance.
• Fall: Apply a fertilizer with a higher phosphorus content to prepare the lawn for winter.

4. Apply Fertilizer Evenly

When applying fertilizer, use a spreader to ensure even distribution. Avoid over-fertilizing as this can damage your lawn. Follow the recommended application rates provided on the fertilizer label.

5. Water Thoroughly After Fertilizing

After applying fertilizer, water your lawn deeply to dissolve the nutrients and move them into the soil. This will help the fertilizer reach the grass roots and maximize its benefits.

Additional Tips for Fertilizing St. Augustine Grass

• Use a slow-release fertilizer: Slow-release fertilizers release nutrients gradually over time, providing continuous nourishment to your lawn.
• Don't fertilize during drought: Avoid fertilizing during periods of extended drought as this can burn your lawn.
• Keep pets and children off fertilized areas: Fertilizers can be harmful to pets and children, so keep them away from treated areas until the nutrients have been absorbed.
• Mow regularly: Regular mowing helps promote new leaf growth and allows fertilizers to reach the base of the grass.

Benefits of Fertilizing St. Augustine Grass

• Enhances Color and Texture: Fertilization improves the green color and texture of your lawn, giving it a more lush and vibrant appearance.
• Promotes Thick Growth: Fertilizers stimulate leaf growth, resulting in a thicker and more dense lawn.
• Reduces Weeds: Fertilizing helps strengthen your lawn, making it more resistant to weed invasion.
• Improves Disease Resistance: Fertilizers provide essential nutrients that help your lawn fight off diseases.
• Increases Drought Tolerance: Fertilizing helps your lawn develop deeper roots, which enhances its ability to tolerate drought conditions.
