When Stage 2 or Stage 3 drought restrictions hit Arlington and the surrounding DFW cities, a lot of homeowners feel stuck. You can’t water freely, the Texas heat is relentless, and your St. Augustine or Bermuda lawn starts looking rough within days. But water restrictions don’t have to mean a dead lawn. With the right strategy, your grass can survive — and even stay reasonably healthy — through the driest stretches of summer. Here’s what actually works, from an Arlington lawn care team that has guided North Texas yards through multiple severe droughts.
Know What Drought Stress Actually Looks Like
Most homeowners panic too early or too late. Real drought stress in St. Augustine shows up as a blue-gray tint to the leaf blades before wilting — the grass is telling you it’s losing more water than it’s taking in. Bermuda and Zoysia go dormant under prolonged drought, turning tan but not necessarily dying. Once you know what to look for, you can respond strategically instead of reactively.
- Blue-gray color: Early stress signal in St. Augustine. The blades are still alive but hurting.
- Footprints that stay compressed: If you walk across the lawn and your footprints linger, the grass lacks the turgor pressure to spring back — it’s thirsty.
- Tan/straw color: Bermuda and Zoysia dormancy. Dormant is not dead. Don’t abandon it.
- Wilting and curling leaf blades: Active wilt in St. Augustine. Water as soon as restrictions allow.
Make Every Drop Count: Watering Smarter Under Restrictions
Under typical Stage 2 restrictions in Arlington, most households are limited to one or two designated watering days per week. That forces you to water efficiently rather than frequently. Here’s how to maximize impact on your allowed days:
- Water deep, not shallow. Running your irrigation for 15 minutes wets only the top inch of soil. Run each zone for 30–45 minutes to push moisture 4–6 inches deep where roots actually live. Deep moisture encourages roots to grow downward, making the grass more drought-tolerant between cycles.
- Water between midnight and 10 a.m. Evaporation loss during midday watering in Texas heat can be enormous. Early morning application lets the water soak in before the sun pulls it back out.
- Check for irrigation inefficiency. A head that’s tilted, clogged, or misaligned wastes a huge portion of your restricted water. Walk your zones while they run and fix any obvious waste before your watering day.
- Use the “cycle and soak” method. If you have clay-heavy North Texas soil, running a zone for 10 minutes, letting it soak for 30, then running another 10 minutes gets more water into the ground than a single 20-minute burst that runs off.
Raise Your Mowing Height Immediately
This is the single fastest, free thing you can do during a drought. Taller grass shades its own soil, dramatically reducing evaporation and keeping root temperatures lower. During drought restrictions, raise your mowing height by at least half an inch:
- St. Augustine: Mow at 3.5–4 inches. Never below 3 during drought.
- Bermuda: Raise to 2–2.5 inches. Bermuda tolerates drought well but still benefits from extra height.
- Zoysia: Keep at 2.5–3 inches. Zoysia is naturally more drought-hardy but will decline faster if scalped.
Also sharpen your mower blade. A dull blade tears the grass, creating jagged wounds that lose moisture rapidly. A clean cut heals faster and stresses the plant less.
Stop Fertilizing Immediately
Applying nitrogen fertilizer during a drought is one of the most damaging things you can do. Fertilizer pushes new leaf growth, and new growth demands water. When water isn’t available, that forced new growth burns and the plant exhausts its reserves trying to sustain it. Hold off on any fertilizer application until you’ve had consistent rain or restrictions are lifted. Your lawn doesn’t need to grow right now — it needs to survive.
Lay Off Weed Control Treatments Too
Herbicides — especially post-emergents — work by being absorbed through the leaf and translocated through the plant. A drought-stressed lawn isn’t translocating much of anything, which means weed control efficacy plummets. Worse, a stressed lawn is also more susceptible to herbicide injury. The weeds can wait. Once the rain returns and the lawn recovers, tackle them then.
Help the Soil Hold What Little Moisture It Gets
North Texas clay soil is notorious for baking into a nearly waterproof crust when it dries out completely. Once that crust forms, the rain and irrigation you do get runs off instead of soaking in. A few tactics help:
- Leave grass clippings on the lawn. They break down quickly and act as micro-mulch, reducing surface evaporation between waterings.
- Consider a wetting agent. Soil surfactants (wetting agents) help hydrophobic clay accept water instead of shedding it. They’re applied as a liquid and genuinely improve water penetration into hardened soil.
- Don’t aerate during drought. Wait until the lawn has recovered and temperatures moderate before pulling cores.
Let Dormancy Do Its Job
Bermuda and Zoysia going dormant isn’t failure — it’s survival. These grasses evolved to handle Texas summers by going tan and waiting. A fully dormant Bermuda lawn can survive weeks without water and green right back up once rain returns. The mistake most homeowners make is trying to force a dormant lawn green with spot-watering, which often just stresses the lawn further or promotes weed pressure. If Bermuda goes dormant, let it. It knows what it’s doing.
St. Augustine is less drought-tolerant and won’t enter full dormancy the same way. It’s more likely to actually die in prolonged drought without some minimal water. If restrictions allow, give St. Augustine at least a “survival watering” of a half-inch every two weeks even if your normal schedule is paused.
Check back on your lawn’s recovery after restrictions lift
Once Stage 2 restrictions ease or significant rain arrives, don’t immediately blast the lawn with water, fertilizer, and weed control all at once. Let the soil absorb moisture for a week, assess what’s truly dead versus dormant, and then ease back into a normal program. Recovery after a rough drought often reveals thin or dead spots that benefit from overseeding or targeted soil work — check our post on why lawns struggle after heavy rain to understand the rebound phase.
When to Call for Help
If you’re coming out of a drought and large patches aren’t greening back up within 2–3 weeks of regular rain and irrigation, those areas may be genuinely dead — not dormant. That’s the time to have a professional assess whether you need resodding, soil amendment, or an irrigation audit.
