Caring for Dallas, GA Bermuda Lawns In Late Summer Heat

Bermuda grass is a favorite turf choice across the Southeast for its heat tolerance, rapid growth, and lush green appearance. But in August, when temperatures peak and the growing season begins to wind down, your Bermuda lawn needs specific care to stay healthy.
As a landscape professional with over 20 years of experience in Southern lawn care, here are my three top tips for keeping Bermuda lawns strong through the final stretch of summer.

1. Complete Your Final Nitrogen Fertilization by Mid-August

August marks the last safe window for high-nitrogen fertilizer applications in the Southeast. Applying nitrogen too late in the season can encourage tender growth that’s vulnerable to winter damage when cooler weather arrives.

• When to Fertilize:
  Aim for your final application between August 1 and August 15.
• What to Use:
  A balanced or slightly high-potassium mix such as 15-0-15 supports root health while still providing the nitrogen Bermuda needs.
• How to Apply:
  Use a broadcast spreader for even coverage and water in thoroughly to push nutrients into the root zone.

💡 Pro Tip: If you’ve aerated recently, follow with a topdressing of compost to add slow-release nutrients and improve soil structure.

2. Maintain Proper Mowing Height to Reduce Heat Stress

August heat can stress Bermuda turf, especially if it’s cut too short. While Bermuda lawns typically thrive at 1.5 to 2 inches, mowing slightly higher during hot, dry stretches helps shade the soil and retain moisture.

• Mowing Guidelines:
  • Standard summer height: 1.5–2 inches
  • In drought or heat stress: Raise height by 0.25–0.5 inches
• Frequency:
  Mow often enough to follow the one-third rule—never remove more than one-third of the grass blade in a single cut. At a minimum you should be mowing weekly.
• Blade Care:
  Keep mower blades razor-sharp to reduce tearing and disease entry points.

💡 Pro Tip: Leave grass clippings on the lawn (“grasscycling”) to return nitrogen naturally and help shade the soil.

3. Water Deeply and Early in the Morning

Bermuda grass is drought-tolerant, but consistent deep watering is key to keeping it vibrant in August’s scorching sun. Shallow, frequent watering promotes weak roots and increases susceptibility to pests and disease.

• How Much Water:
  Supply about 1–1.25 inches per week, including rainfall.
• Best Time to Water:
  Early morning (between 3 a.m. and 9 a.m.) to reduce evaporation and allow grass blades to dry quickly, minimizing fungal risks.
• Watering Technique:
  Use fewer, deeper sessions rather than daily light sprinklings—this encourages roots to grow deeper, improving drought resistance.

💡 Pro Tip: If your lawn shows signs of drought stress—like footprints remaining visible after walking across it—it’s time to water.

Be The Envy Of Your Neighborhood With August Bermuda Lawn Care

By finishing nitrogen fertilization on time, mowing strategically, and watering deeply, you’ll prepare your Bermuda lawn for a healthy transition into fall. August is also a good time to spot-treat summer weeds, inspect for pests like armyworms, and plan your fall pre-emergent applications in September.

When you follow these expert-approved steps, your Dallas, Georgia Bermuda lawn will stay thick, green, and ready to handle whatever the rest of the year brings.
