How do you water your lawn during a hot Texas summer?
To some of us, lawn-watering seems a great mystery. We know we need to water our lawns so the sun doesn’t scorch the grass.
But when do we water? How often can we water? How deep should we water?
We can solve these mysteries for you. Our summer watering tips will help you care for your lawn, no matter how high summer temperatures climb in central Texas.
When do I water?
Experts recommend you water in the morning. Any time before 10 a.m. is best. But it’s better to water in the early morning, between midnight and 6 a.m.
Many irrigation systems have timers that can water during set periods.
Austin residents have conservation stage restrictions:
- If you have a hose-end irrigation system, you can only water on watering days between midnight and 10 a.m., or between 7 p.m. and midnight.
- If you have an automatic irrigation system, you can only water on watering days between midnight and 10 a.m., or between 7 p.m. and midnight.
- If you hand-water your lawn, you can water any time of day and on any day of the week.
- If you use soaker hoses or drip-irrigation systems, you can water any day or time.
During summer heat, we recommend you water once a week only, and water deeply so your roots can grow deeper in search of the water. This will create a healthier lawn. However, this only works if you have deep soil (we recommend a watering level of 1 inch).
Don’t know how much water your lawn gets? Try setting a tuna or coffee can on the lawn. As you water, check this can to see how long you must water to reach 1 inch.
Of course, lawns with shallow soil or rocky soil should be watered for shorter periods—twice per week, if your city’s watering schedule allows this. Always remember to water only during these arranged times.
What is Austin’s watering schedule?
You can use this website tool to determine your permitted watering in the city of Austin.
Assigned watering days are determined by property type and type of irrigation system. They’re also based on your street address—whether an address number is odd or even.
- Home address can water twice a week:
- Even addresses with automatic irrigation can water on Thursdays
- Odd addresses with automatic irrigation can water on Wednesdays
- Even addresses with hose-end irrigation can water on Thursdays and Sundays
- Even addresses with hose-end irrigation can water on Wednesdays and Saturdays
- Commercial addresses can only water once a week:
- Even-numbered addresses can water on Tuesdays
- Odd-numbered addresses can water on Fridays
- (Public schools can water on Mondays)
Some additional watering suggestions:
- Do not water from noon to 6 p.m. This is the day’s hottest period. Water can evaporate and not sink into your lawn.
- If you have thatch, or built-up dead grass in between your living grass, this may keep water from sinking into your lawn. Have a professional rake out thatch so you can water properly.
- Bermuda grass and buffalo grass have very modest watering needs. If your city tightens watering restrictions, these lawns can go up to three weeks without being watered (depending on summer temperatures). Meanwhile, zoysia grass and St. Augustine grass can’t go longer than 2 weeks without suffering damage.
- Remember to adjust your watering level after rain. If you overwater your lawn, you may harm your lawn more than if you’d not watered at all.
- Check your irrigation system often for sprinkler heads. These may become damaged or aim toward the sidewalk and street. Either issue can waste water. Fix the problems, or call a professional to fix them for you as soon as possible.
