How Long Should You Run A Sprinkler To Water Your Lawn?

Watering Your Bermuda Lawn in Dallas, TX

In the hot and humid summers of Dallas, TX, maintaining a vibrant Bermuda grass lawn involves not just regular watering but doing so in a way that promotes deep root growth and efficient water use. Bermuda, known for its resilience and beautiful, dense growth, requires a thoughtful approach to irrigation, especially given the region’s climate. Here’s a comprehensive guide on how long you should run your sprinkler to keep your Bermuda lawn in peak condition throughout the summer.

Understand Your Lawn’s Needs

Bermuda grass thrives when it receives about 1 to 1.25 inches of water per week, whether from rainfall or supplemental watering. This helps the lawn maintain its lush appearance and supports deeper root development, which is crucial for withstanding drought conditions that are not unusual in Dallas.

Calculating Sprinkler Duration

To determine how long to run your sprinkler, you’ll first need to understand your sprinkler system’s output, measured in inches per hour. This can vary significantly based on the type of sprinkler you use. A simple catch cup test can help you measure this:

  1. Place several catch cups (tuna cans work well due to their uniform size) around your lawn at different distances from the sprinkler.
  2. Run the sprinkler for 15 minutes.
  3. Measure the water depth collected in each can, averaging these measurements to get a rough estimate of your sprinkler’s output in inches per hour.

For Bermuda grass in Dallas, aiming for 1 to 1.25 inches per week, here’s a straightforward formula:

\[ Sprinkler Duration (in hours) = Desired Water Depth (in inches) ÷ Sprinkler Output (in inches per hour) \]

Assuming your sprinkler system outputs 0.5 inches of water per hour (a common rate for many oscillating and rotary sprinklers), to achieve 1 inch of water, you would need to:

\[ 1 inch ÷ 0.5 inches per hour = 2 hours \]

Implementing Efficient Watering Practices

  • Water Early in the Morning: To minimize evaporation and ensure the water reaches the roots, it’s best to water your Bermuda lawn early in the morning before the sun gets too hot.
  • Frequency Over Duration: Especially in Dallas’s climate, it’s beneficial to split your watering sessions into two half-inch applications over the week rather than a single one-inch watering. This promotes better absorption and prevents water waste through runoff, a common issue with heavier soil types found in the area.
  • Adjust to Rainfall: Always account for rainfall in your weekly watering calculation. If the area receives significant rainfall, reduce your sprinkler use accordingly to avoid overwatering.
  • Monitor Your Lawn: Pay attention to signs of dehydration in your Bermuda lawn, such as blue-gray coloration and footprints that remain visible longer than usual. These indicators suggest your lawn needs watering.


Keeping your Bermuda lawn lush and healthy in the demanding summers of Dallas, Texas, requires careful water management. By understanding your sprinkler system’s output and adjusting your watering schedule based on the specific needs of Bermuda grass, you can maintain a vibrant, resilient lawn that’s both a joy to behold and an oasis in the heat. Remember, the best approach is one that conserves water while providing your lawn with the hydration it needs to thrive.
