Each summer in Austin, Texas, feels like an endless heatwave, but that doesn’t have to mean an endless waste of water. By now, Austinities are pretty familiar with citywide water restrictions implemented to help conserve water during drought periods. So, how can you stay mindful of your lawn’s water use without ruining your grass? We’ve got some lawn watering tips to help you out.

1. Topdressing the Soil for Moisture Retention

Regarding Austin’s soil types, the common thread seems to be that they’re often low in organic matter. This means the soil has a harder time holding onto moisture, meaning high temperatures and blaring sun can leave the soil dry as a bone. 

To solve this, topdress your soil with an organic-rich compost or mulch to restore that essential moisture. Adding a bit of natural fertilizer to the mix is also a great way to increase your soil’s nutrient content and naturally boost its fertility. But be sure to choose a fertilizer with low nitrogen content, as too much nitrogen can make the grass grow faster and suck up more water.

2. Timing is Key

Early morning, before 10 am, is the ideal time to pour on the H2O since temperatures and wind speeds are lower. That’s when water is most likely to be absorbed into the soil and less likely to evaporate or blow away without ever reaching your grass. 

As a general rule, it’s best to water your lawn no more than once a week. During spring and fall, your grass can go up to two weeks between waterings. 

3. Be Aware of How Much You’re Watering

Be mindful of how much water you’re using to prevent waste and harmful overwatering. No more than one inch of water per week is a good rule of thumb – and that includes rainfall.

Usually, a good soaking of an inch is enough. However, depending on your Austin grass type, you may go up to 1.5 inches. For instance, a Bermudagrass lawn needs 1.5 inches during a typical summer week, whereas Zoysiagrass and Buffalograss only need 1 inch.

4. Deep Waterings Over Shallow Sprinklings

If you want your grass to be resilient enough to survive a scorching summer, its roots will need to dig deep into the soil. Watering deeply and infrequently will encourage the grass roots to grow deeper. Frequently watering with shallow pours can stunt growth and end up doing more harm than good. 

Note that if you overwater your lawn, you may end up weakening the root system and depleting the precious oxygen that grass roots need to thrive and survive.

5. Aerate Your Lawn Regularly For Maximum Effectiveness

At least once a year, it’s a good idea to aerate your lawn by puncturing 6-inch holes to help increase the soil’s water absorption. Aeration will also help prevent flooding and runoff, as well as letting the vital nutrients get down to the deep roots. 

6. Check Your Irrigation System

Run a checkup on your irrigation system come springtime and make sure there aren’t any leaking pipes or hoses that need repair. This way, you’ll double-check you’re getting the most bang for your water buck!

7. Keep an Eye on Your Sprinkler System

It’s important to check the alignment of your sprinkler heads regularly, particularly after you’ve cut your lawn. Make sure you replace any broken or clogged parts right away to prevent water waste.

8. Mulch the Grass Clippings

When you mow, don’t forget to mulch the grass clippings. Not only is this a great way to break down the clippings and return their nutrients to the soil quickly, but it’s also a natural way to reduce evaporation. Just be careful not to smother the grass with too many clippings!

FAQ About Lawn Watering in Austin

How long to run sprinklers in Austin? 

It depends on the grass type and your sprinkler system, but a good general rule is to run the sprinkler for 30 minutes or one hour max, one day a week. In the fall and winter months, you may need to water less. 

What type of grass grows best in Austin, TX?

The most common types are warm-season grasses, such as:
• St. Augustinegrass 
• Buffalograss
• Bermudagrass
• Zoysiagrass

Is it better to water the lawn in the morning or evening in Texas? 

Both are good options. Just make sure to avoid the 12:00 – 6:00 pm window when the sun is at its strongest. Early morning and late evening are the best times to water your lawn in Austin.

What type of sprinkler should I use? 

If you have an automatic sprinkler system, you’ll want to use a timer-activated sprinkler that suits the area you want to water. Hose-end sprinklers are great for smaller gardens, single-family dwellings, and commercial properties. Another option is the soaker hose, which works best for circular beds and vegetable gardens.

What else can I do to keep my lawn green? 

In addition to regular watering, aerating the soil and adding an organic-rich compost or mulch can make a big difference in the health of your lawn. Mowing regularly and mulching the clippings are also great ways to keep your grass looking lush and green. 
Avoid common lawn care myths such as ignoring the lawn in winter, fertilizing only once per year, or trying cheap DIY aeration methods.
