When to Plant St. Augustine Grass

Here are the steps you need to plant St. Augustine grass seed

St. Augustine grass plugs

Measure Your Lawn

To ensure you buy enough St. Augustine grass plugs, measure the exact measurements of the area you’ll be planting. The area covered by a tray of 18 plugs is approximately 32 square feet.

Prep the Area

Rent a sod-cutter to remove the old sod and vegetation if you’re replacing an existing lawn. Then, 2 weeks before planting, use a non-selective herbicide to eliminate weeds; make sure you pick a product that won’t leave a residue that will affect the newly planted St. Augustine grass.

You can hand-pull a few weeds if you just have a few but make careful to get the complete root system.

Apply Lawn Repair

Apply a lawn repair treatment for St. Augustine Lawns evenly across the planting area, and ensure no bare ground is visible. To help St. Augustine grass plugs fill in faster, you can find such products mix fertilizer and a mulch which absorbs up to 6 times its weight in water.


Water the Ground

Before you plant, make sure the area is well watered. Watering makes the earth more pliable and provides instant moisture to the roots of the St. Augustine grass plugs and helps grass spread quickly.

The water you apply should seep into the soil rather than remain on top of it. Continue to wet the patch until totally saturated and no more water is absorbed, which could take several minutes.

Start Digging

Dig holes in a diagonal planting pattern, forming a diamond with each group of four holes. The holes themselves should be separated at a distance of 12 inches, so holes across the center of each diamond will be 15 inches apart.

Each hole should be larger than the root ball of the plug, but at the same depth. A grass plugging tool can also be purchased or rented at your local hardware shop or online. With a lot less effort, this tool creates exactly sized plug holes.

Position Your Plugs

Make sure each plug is level with the surrounding ground by pressing a plug’s root ball firmly into each hole. If your holes wind up being too deep, you can make sure they are completely filled by pushing in some nutrient-rich soil.

St. Augustine grass watering schedule

Water Your Lawn

Maintain a strict watering schedule every day or as needed until the plugs are well-rooted and spreading. The roots will usually take 7-14 days to establish themselves. After that, unless your lawn has received a lot of rain, water it once a week.

Check for Bugs & Disease

St. Augustine grass lawns that have just been planted need to be protected as they establish themselves. Pests such as Southern Chinch bugs and disease can affect both the roots and the turf. Keep a tight eye on your grass. If you see brown patches (chinch bugs) or mildew forming, you’ll need to take action. (Learn How To Make St Augustine Grass Thicker)

Nitrogen, potassium, and phosphorus in the ratio 3:2:1 are the optimum fertilizers for St. Augustine grass development.

Nitrogen is critical for the growth of St. Augustine grass, and around 1 pound (0.45 kg) of soluble nitrogen per 1,000 square feet (92.9 m2) is required, implying a high coating of nitrogen. When using nitrogen fertilizer in the initial stages, use caution and apply sparingly.
