how to grow st augustine grass from runners

St. Augustine grass is a popular choice for lawns in warm climates due to its lush, green appearance and relatively low maintenance needs. One of the most effective and economical ways to establish a St. Augustine lawn is by planting it from runners, also known as stolons. This method allows for quick spread and a strong, healthy lawn. This guide will walk you through the process step-by-step.

Preparing the Soil for Your St. Augustine Grass Runners

Before you even think about planting, preparing your soil is crucial for success. Healthy soil provides the foundation for a thriving lawn.

Testing Your Soil

First, test your soil's pH. St. Augustine grass prefers slightly acidic to neutral soil (pH 6.0-7.0). You can purchase a soil testing kit at most garden centers. Adjust the pH accordingly using lime (to raise pH) or sulfur (to lower pH) based on the test results.

Improving Soil Structure

Next, consider your soil's composition. St. Augustine grass needs well-drained soil. If your soil is heavy clay, amend it with organic matter like compost to improve drainage and aeration. This will allow roots to breathe and grow properly. Adding compost also enhances nutrient content.

Clearing the Area

Finally, clear the planting area of any weeds, rocks, and debris. Existing weeds will compete with your new grass for nutrients and water. A clean, level surface ensures even growth and prevents drainage issues. A tiller or garden spade can help with this process.

Selecting and Preparing Your St. Augustine Grass Runners

Choosing healthy runners is essential for a successful planting.

Sourcing Your Runners

Obtain your runners from a reputable source, such as a local nursery or landscaping company. Ensure the runners are green, healthy, and free of disease or pests. Avoid runners that are brown, dried out, or show signs of damage.

Inspecting the Runners

Carefully inspect each runner before planting. Remove any dead or damaged portions. Healthy runners will have vibrant green leaves and firm, well-developed nodes. These nodes are where roots and new shoots will emerge.

Planting Your St. Augustine Grass Runners

Now comes the planting! Here's how to do it correctly:

Laying the Runners

Lay the runners horizontally on the prepared soil, spacing them 6-12 inches apart. Overlap the runners slightly to ensure complete coverage and quicker establishment. The spacing will determine how quickly your lawn fills in.

Securing the Runners

Lightly press the runners into the soil to ensure good soil contact. Avoid pressing too hard, which could damage the delicate roots and stolons. You can use a garden rake to gently cover the runners with a thin layer of soil.

Watering

After planting, water deeply and thoroughly. This helps the runners establish root contact with the soil and aids in their quick establishment. Consistent watering is crucial, especially during the first few weeks.

Maintaining Your New St. Augustine Lawn

After planting, consistent care is essential for the long-term health of your lawn.

Watering Schedule

Water deeply and regularly, especially during dry periods. The frequency will depend on your climate and soil conditions. Aim for 1-1.5 inches of water per week, delivered through deep, infrequent watering sessions rather than many short ones. This promotes deep root growth.

Fertilizing

Fertilize your new lawn according to the package directions of a fertilizer specifically formulated for St. Augustine grass. Avoid over-fertilizing, as this can lead to excessive growth and disease. Spring and fall are generally the best times to fertilize.

Weeding

Regularly remove any weeds that emerge. This will prevent competition for nutrients and water, allowing your St. Augustine grass to flourish. Hand-weeding or spot-treating with a suitable herbicide are common methods for weed control.

Mowing

Begin mowing once the grass has established itself, usually after a few weeks. Mow at a height of 2-4 inches. Avoid cutting more than one-third of the grass blade at a time to prevent stress and damage to the grass plants. Sharpen your mower blades regularly for a clean cut to prevent ragged edges.

Troubleshooting Common Issues

While relatively low maintenance, even St. Augustine grass from runners can face problems.

Yellowing or Browning

Yellowing or browning can indicate various issues, including nutrient deficiencies, disease, or pest infestation. Test your soil's pH and nutrient levels. Consult with a local gardening expert or your nursery to diagnose and treat the specific problem. In some cases, simple adjustments to watering or fertilization can resolve issues.

Patchy Growth

Patchy growth might be due to poor soil preparation, uneven watering, or pests. Ensure proper soil preparation prior to planting. Check for areas with poor drainage or compacted soil.

Weeds

Persistent weeds indicate a need for improved weed control strategies. Consider pre-emergent herbicides to prevent weeds from sprouting, or spot-treat weeds with a selective herbicide labeled for St. Augustine grass.

By following these steps, you'll be well on your way to establishing a lush, healthy St. Augustine grass lawn using runners. Remember, patience and consistent care are key to success.
