How to Lay St. Augustine Grass: A Complete Guide

How to Lay St Augustine Grass

Preparing the Area for St Augustine Grass Installation

Before laying St Augustine grass, it’s important to prepare the area properly to ensure successful installation. Follow these steps to get your lawn ready:

  • Clear the area: Remove any existing grass, weeds, or debris from the area where you plan to install St Augustine grass. Use a rake or a turf cutter to eliminate all vegetation.
  • Level the ground: Ensure the ground is even and level. Fill any low areas with topsoil and use a rake or shovel to spread it evenly. Avoid creating slopes or uneven spots.
  • Test the soil: Conduct a soil test to determine its pH level and nutrient content. St Augustine grass thrives in slightly acidic soil with a pH range of 6.0 to 6.5. If your soil is too acidic or alkaline, you may need to adjust it accordingly.
  • Amend the soil: Based on the soil test results, add any necessary amendments to improve the soil structure and provide essential nutrients for the grass. This may include adding organic matter, such as compost or peat moss.
  • Remove rocks and debris: Take the time to pick up any rocks, roots, or large debris that could interfere with the installation process or create unevenness in the final lawn surface.
  • Water the area: Before installing the St Augustine grass, thoroughly water the prepared area to moisten the soil. This will help the roots establish more easily.

Choosing and Measuring St Augustine Grass

The next step in laying St Augustine grass is selecting the right type and measuring the area accurately. Follow these guidelines to ensure a successful installation:

  • Choose the right St Augustine grass variety: There are several St Augustine grass varieties available, each with its own characteristics. Consider factors such as shade tolerance, disease resistance, and maintenance requirements when choosing the best variety for your specific lawn.
  • Measure the area: Measure the length and width of the area where you intend to install the grass. Multiply these measurements to get the total square footage. Add an extra 5-10% to account for any cuts or waste during installation.
  • Order the correct amount: Contact a reputable turf supplier and provide them with the square footage of your lawn. They will help you determine the appropriate amount of St Augustine grass needed for your project.

Installing St Augustine Grass

Now that you have prepared the area and obtained the necessary materials, it’s time to install the St Augustine grass. Follow these steps for a successful installation:

  • Start with fresh sod: It is recommended to install fresh St Augustine sod for the best results. Avoid using sod that has been sitting for too long, as it may have reduced viability.
  • Begin at a straight edge: Start laying the sod along a straight edge of your lawn, such as a driveway or sidewalk. This will serve as a guide for the rest of the installation process.
  • Fit the sod tightly: Place the sod pieces tightly together without overlapping or leaving gaps. This will ensure a seamless and uniform appearance in your lawn.
  • Trim as needed: Use a sharp knife or sod cutter to trim any excess sod to fit around curves, trees, or other obstacles in your lawn.
  • Water immediately: After laying a few rows of sod, water the newly installed grass thoroughly. This will help settle the sod and promote root growth.
  • Roll the sod: Use a lawn roller to gently press the sod into the soil. This ensures good soil-to-root contact and prevents air pockets.
  • Water regularly: After installation, water the St Augustine grass regularly to keep the soil moist and aid in root establishment. Avoid overwatering, as it can lead to shallow root growth and other issues.

Post-Installation Care for St Augustine Grass

Proper post-installation care is essential to help your St Augustine grass establish a healthy and lush lawn. Follow these tips for maintaining your new lawn:

  • Keep the grass moist: Water the St Augustine grass frequently during the first few weeks to encourage root growth. Be careful not to let the grass dry out, as this can hinder establishment.
  • Mow at the right height: Once the grass reaches a height of around 3-4 inches, mow it to a height of about 2-3 inches. Avoid cutting too short, as it can weaken the grass and make it more susceptible to pests and diseases.
  • Fertilize as needed: St Augustine grass benefits from regular fertilization. Follow the recommended fertilization schedule for your specific grass variety and climate to promote healthy growth.
  • Control weeds: Keep an eye out for weeds and promptly address any issues. Apply appropriate herbicides or manually remove weeds to prevent competition for resources.
  • Address pest and disease problems: Monitor your lawn regularly for signs of pests or diseases. Take appropriate measures, such as using pest control products or seeking professional help, to keep your St Augustine grass healthy.

2. Test the soil: Conduct a soil test to determine the pH level and nutrient composition of your soil. This will help you determine if any amendments are needed.

3. Loosen the soil: Use a tiller or garden fork to loosen the top 6 to 8 inches of soil. This will help improve drainage and root penetration.

4. Add organic matter: Incorporate organic matter such as compost or peat moss into the soil to improve its fertility and structure.

5. Level the surface: Rake the soil surface to ensure it is level and free from any large bumps or depressions.

6. Water the soil: Before laying the St. Augustine grass, thoroughly water the prepared soil to help settle it and provide a moist environment for the roots.

When is the best time to lay St. Augustine grass?

1. Initial watering: Immediately after installation, thoroughly water the grass to a depth of approximately 6 inches. This helps settle the soil and ensures the roots make good contact.

2. Daily watering: For the first two weeks, water the grass daily to keep the soil consistently moist. Water deeply, applying approximately 1 inch of water each time.

3. Gradual reduction: Gradually reduce the frequency of watering after the initial two weeks. Water deeply but less frequently to encourage deeper root growth.

4. Watering schedule: Once the grass is established, water it deeply once or twice a week, depending on the weather conditions. Adjust the frequency based on rainfall and the appearance of the grass. Avoid overwatering as it can lead to shallow root growth and other issues.

How long does it take for St. Augustine grass to fully establish?

The establishment period for St. Augustine grass can vary depending on various factors such as temperature, soil conditions, and maintenance practices. Generally, it takes about 2 to 4 weeks for the roots to fully establish, but complete coverage and density may take several months. Regular watering, fertilization, and mowing will aid in the grass’s establishment and speed up the process.

Can I lay St. Augustine grass over an existing lawn?

It is not recommended to lay St. Augustine grass directly over an existing lawn. The old grass will create a barrier that prevents the new grass from establishing properly. It is best to remove the existing lawn by either manually removing it or using appropriate herbicides. Once the old grass is removed, follow the necessary steps to prepare the soil and then proceed with laying the St. Augustine grass.

Final Thoughts

To lay St. Augustine grass, start by preparing the soil by removing any weeds, rocks, or debris and leveling the surface. Then, apply a layer of organic compost or topsoil to improve the soil quality. Next, lay down the sod pieces tightly, ensuring they are properly aligned. Water the newly laid sod immediately and continue to keep it hydrated for the next few weeks. Regularly mow the grass once it reaches a height of about 3 inches. Remember, when laying St. Augustine grass, thorough soil preparation and consistent watering are key to establishing a healthy and vibrant lawn.
