How to Fix Bald Spots in Your Precious Lawn

Why Do Bald Spots Appear in St. Augustine Grass?

Before diving into solutions, it’s important to understand the root cause of the problem. St. Augustine grass, while resilient, has its quirks. Here are the most common reasons bald spots develop:

• Foot Traffic and Compacted Soil: High-traffic areas often develop compacted soil, which prevents roots from growing deep.

  • Tip: Install stepping stones or a path in high-traffic areas to reduce stress on your lawn.

• Drought Stress: Inconsistent watering, especially during Texas summers, can lead to thinning grass and brown patches.

  • Tip: Use a sprinkler timer to ensure consistent watering during dry periods.

• Fungal Diseases: Warm, humid conditions promote diseases like brown patch, which causes circular discoloration.

  • Tip: Water early in the morning to let the grass dry during the day, reducing fungal growth.

• Pests: Chinch bugs and grubs damage your lawn by feeding on the roots, leading to thinning and patchy grass.

  • Tip: Inspect your lawn regularly for pests, especially in sunny, dry areas.

• Shade and Poor Mowing Practices: Grass in overly shaded areas or mowed too short is weaker and more prone to damage.

  • Tip: Avoid mowing your St. Augustine grass shorter than 3 inches to retain strength and moisture.

Step-by-Step Guide to Repairing Bald Spots

Repairing bald spots in St. Augustine grass requires some tools, effort, and patience. Follow these steps to get your lawn back in shape:

Step 1: Diagnose the Problem

Start by understanding the root cause of the bald spots:

• Check for Pests: Pull back grass in the affected area and look for chinch bugs, grubs, or other pests. If found, apply a targeted insecticide.

  • Tip: Test for chinch bugs by placing a can (open at both ends) into the soil and filling it with water. Bugs will float to the surface.

• Test for Fungus: Look for circular patches of discolored grass, which indicate fungal diseases like brown patch. Treat with a fungicide like Bonide Fungicide.

  • Tip: Avoid fertilizing during fungal outbreaks, as this can make the issue worse.

• Assess Soil Compaction: Hard, compacted soil needs aeration to improve water and nutrient flow.

  • Tip: Use a screwdriver to test compaction. If it’s difficult to push into the soil, aeration is needed.

Step 2: Prepare the Area

Preparing the area is crucial for a successful repair:

1. Remove Dead Grass: Rake out any dead grass, weeds, or debris.

   • Tip: Use a stiff brush to clear debris near tight spots or borders.

2. Loosen the Soil: Aerate the soil using a tool like the Yard Butler Lawn Coring Aerator.

   • Tip: Aerate when the soil is slightly moist for easier penetration.

3. Level the Area: Add a thin layer of sandy loam or compost to improve drainage and create a smooth surface for planting.

   • Tip: Use a flat board or level to evenly distribute soil.

Step 3: Replant Using Plugs or Sod

St. Augustine grass doesn’t grow from seed, so you’ll need to replant bare areas:

• Sod for Large Areas: Lay fresh sod over bald spots, trimming to fit. Press firmly to ensure soil contact.
  • Tip: Lightly water the soil before laying sod to encourage root bonding.
• Plugs for Small Patches: Use plugs like Planket Lawn Patch Seed Plugs, spacing them 6–12 inches apart.
  • Tip: Stagger plugs for faster coverage and stronger growth.

Step 4: Water and Fertilize

Once the grass is planted, proper watering and fertilizing will ensure success:

• Water Regularly: Water lightly but frequently for the first 10–14 days to establish roots.
  • Tip: Avoid overwatering, as it can lead to fungal growth or root rot.
• Fertilize Wisely: Use a starter fertilizer like Pennington Lawn Booster to provide essential nutrients.
  • Tip: Opt for a slow-release fertilizer to encourage steady growth.

Step 5: Maintain and Monitor

Maintenance is key to long-term success:

• Limit Foot Traffic: Keep people and pets off the repaired areas until grass is established.
• Mow Carefully: Wait until the grass reaches about 3 inches before mowing, and use a sharp blade to avoid tearing.
  • Tip: Leave grass clippings on the lawn after mowing to return nutrients to the soil.
• Inspect Regularly: Watch for pests, fungal issues, or signs of stress, and treat problems early.

Preventing Bald Spots in the Future

Once your lawn is lush and green, keep it that way with these prevention tips:

• Aerate Annually: Loosen compacted soil every spring to encourage deep root growth.

  • Tip: Combine aeration with fertilizing for best results.

• Water Smartly: Water deeply but less frequently to encourage stronger roots.

  • Tip: Use a tuna can to measure 1 inch of water per session.

• Fertilize Seasonally: Use a balanced fertilizer at key times of the year.

  • Tip: Test your soil to determine the exact nutrients your lawn needs.

• Control Pests: Regularly inspect for signs of bugs and treat issues promptly.

  • Tip: Encourage natural predators like birds by adding bird feeders to your yard.
