Proper chemical weed control not only ensures a clean planting area for your St. Augustine grass, but also helps maintain a healthy, weed-free lawn throughout the growing season.

Planting Methods for St. Augustine Grass

St. Augustine grass can be planted using a variety of methods, including sod, plugs, or sprigs. Each method offers different advantages and establishment times, so it’s important to choose the one that best suits your needs and preferences.

In the following sections, we will discuss the benefits and drawbacks of each planting method and provide guidance on how to successfully plant St. Augustine grass using these techniques.

Sod Installation

Sod installation is the quickest method for establishing St. Augustine grass and is an excellent choice to create an instant lawn. It’s known for its thick and lush coverage.

However, this method can be more expensive than other planting options, such as plugs or sprigs. To successfully install St. Augustine soil, you’ll first need to prepare the soil by ensuring it is moist 3-4 inches deep and filling any low or uneven areas with topsoil.

Start by laying the St. Augustine sod pieces over the bare, moist soil.

Fit the edges tightly together in a staggered brick-like pattern to avoid any open cracks. Be sure to keep the newly laid soil moist by watering it frequently during the establishment period.

With proper care and maintenance, your St. Augustine sod will quickly establish, providing a beautiful, lush lawn.

Plugs and Sprigs

Plugs and sprigs are more affordable planting options for St. Augustine grass, but they require more time and care to establish a full, dense lawn.

St. Augustine plugs are small squares of sod, typically measured in square feet, or commercially available plugs that are inserted into holes or open furrows and firmly tamped into place. Stolons are nodes on a plant’s stem where its sprouts grow. Sprigs are created when these stolons are planted end-to-end in furrows 6-12 inches apart.

Both St. Augustine grass plugs and sprigs should be planted during the late spring or early summer for optimal establishment. Make sure to keep the soil moist during the establishment period to encourage healthy root growth and successful establishment.

With patience and proper care, your St. Augustine plugs or sprigs will eventually fill in and create a dense, attractive lawn.

Caring for Your Newly Planted St. Augustine Lawn
