  • Soil pH should ideally range between 5.0 and 8.5 for optimal growth.

Soil Conditions For Successful Growth Of St. Augustine Grass

To ensure successful growth of St. Augustine grass, it is essential to pay attention to the soil conditions. Sandy or well-draining soil is recommended, as it allows the roots to establish and spread more easily. It also helps prevent waterlogging, which can be detrimental to the grass’s health.

Moreover, maintaining the proper pH level of the soil is crucial. Conducting a soil test can help determine the pH level and make necessary adjustments if needed. Adding lime to increase pH or sulfur to decrease it can help create an optimal environment for the growth of St. Augustine grass.

Another aspect to consider is the nutrient content of the soil. St. Augustine grass thrives in soil that is rich in nutrients. Using a phosphorus-laden fertilizer for the first 3 to 4 months after installation can provide the necessary nutrients for the roots to establish. Afterward, switching to a normal nitrogen fertilizer will sustain healthy growth.

  • Use sandy or well-draining soil
  • Conduct a soil test for pH level
  • Adjust pH level with lime or sulfur
  • Use a phosphorus-laden fertilizer initially
  • Switch to normal nitrogen fertilizer after 3-4 months

Proper Care And Maintenance For St. Augustine Grass

Proper care and maintenance are essential to ensure the optimal spread and growth of St. Augustine grass in Florida.

One crucial aspect is watering. During the initial establishment phase, it is important to water the newly planted grass plugs multiple times a day for the first 7 to 10 days. This will help the roots take hold and promote the spread of the grass. Gradually scaling back the frequency of watering afterward, while still ensuring adequate hydration, allows the roots to become more resilient and self-sufficient.

Weeds can pose a significant threat to the growth of St. Augustine grass. Allowing weeds to grow freely in the yard can steal vital nutrients from the grass, impeding its spread. Using a pre-emergent herbicide can be effective in preventing weed growth and maintaining a healthier lawn.

Certain weeds, including dallisgrass, crabgrass, and broadleaf weeds, are particularly notorious for their negative impact on St. Augustine grass growth and spread. Regularly monitoring the lawn for the presence of these weeds and taking prompt action to remove them can help ensure a more vigorous and spreading lawn.

Planting Tips For St. Augustine Grass Lawns

Planting St. Augustine grass plugs is a popular and relatively easy method to establish a lawn. However, following proper planting techniques is crucial for successful establishment and subsequent spread of the grass.

Timing plays a significant role in planting St. Augustine grass. It grows best during the warmth of spring and summer when temperatures range between 80-100 °F. To allow sufficient time for growth before the first fall frost, it is recommended to plant the plugs at least 90 days before the anticipated frost date.

Preparing the planting area is an essential step. The exact dimensions of the area should be measured accurately to determine the number of plugs needed. An existing lawn can be removed using a sod-cutter, and a non-selective herbicide can be applied to kill weeds.

Once the area is prepared, applying Scotts® EZ Patch™ Lawn Repair for St. Augustine Lawns can provide a uniform covering of bare ground. The area should be thoroughly watered before planting to ensure the plugs receive sufficient moisture upon placement.

When planting the plugs, digging holes in a diagonal pattern, spaced 12 inches apart is recommended. Each hole should be slightly larger than the plug’s root ball. After planting, filling in any holes with nutrient-rich soil and watering daily until the plugs are rooted and start spreading ensures a successful establishment. This process typically takes 7-14 days.
