1. Color changes<\/span><\/h2>
“One of the first indicators of drought stress is a change in turfgrass color and leaf shape,\u201d says Dean Minchillo, Urban Water Program Specialist at Texas A&M AgriLife Extension<\/a>. \u201cAs the grass dries out, it shifts from green to a bluish-gray hue.\u201d<\/p>
When grass blades are dehydrated, they fold, roll, or wilt, which changes how light reflects off the surface. This creates that telltale blue-gray color before the grass turns yellow or brown. Don\u2019t worry. It bounces back quickly with proper watering. If you wait until it’s yellow or brown, recovery takes much longer. <\/p>

2. Footprint test<\/span><\/h2>
The easiest way to check if your lawn needs water, according to Minchillo, is simple. “Walk across your lawn. If your footprints remain visible and the grass doesn’t spring back, it’s likely too dry.” A thirsty lawn holds your footprints because grass blades lose what scientists call “turgor pressure,” the internal water pressure that keeps grass standing upright. <\/p>
Try this test in the morning when your grass is most hydrated. If you can still see clear footprints after a few minutes, it’s time to water. For best results, water early morning when temperatures are cooler and evaporation is minimal. <\/p>

Look for surface cracking, starting with small hairline cracks that grow into larger gaps several inches wide in clay soil. You’ll also notice water from recent rains or sprinklers just sits on top instead of soaking in, creating puddles that evaporate fast.<\/p>
“Soil moisture is key to determining whether your lawn is getting enough water. Ideally, you want the soil to be moist to a depth of at least six inches,” says Minchillo. “A simple way to check moisture depth is with a screwdriver. Push it into the soil \u2014 if it’s hard to penetrate, the soil is dry.\u201d<\/p>
If your screwdriver stops at 2-3 inches even after watering, you’re dealing with compacted soil. This happens most in high-traffic areas where people walk regularly. Aeration solves this by creating holes that let water flow down to the roots where it’s needed most.<\/p>

4. Curling grass blades<\/span><\/h2>
Get down close for this inspection \u2013 it’s worth the detailed look. Water-stressed grass blades fold lengthwise to reduce their surface area. “You might also notice the blades curling up like little straws, especially in St. Augustine lawns,” notes Minchillo.<\/p>
This survival mechanism reduces the leaf surface area exposed to the sun and wind, limiting water loss through evaporation. For the best results, check older grass blades instead of new ones. Young leaves can look wilted even when they have enough water, so look at the mature grass for a true picture. <\/p>

5. Slow growth<\/span><\/h2>
If you’re mowing your grass less often, it might be sending you a message. Without enough water for photosynthesis, grass simply can’t produce the energy it needs to grow. “Shallow watering leads to shallow roots, which dry out quickly in the summer and reduce lawn quality,” notes Minchillo<\/p>
When grass gets severely stressed, it will eventually go dormant and stop growing completely, and at this point, you’re looking at weeks of recovery time once you resume proper watering. <\/p>

6. Insect damage<\/span><\/h2>

Photo Credit: JJ Gouin<\/a> \/ Adobe Stock<\/figcaption><\/figure> Water-stressed grass turns into an easy target for destructive insects because weakened turf simply can’t fight back. White grubs and chinch bugs are common summer lawn pests<\/a> that leave irregular brown or yellow patches that feel spongy underfoot. You can actually peel back sections of damaged turf like old carpet if the root system has been destroyed.<\/p>
The key is catching insect damage early. Look for patches that don’t respond to watering. If brown spots persist even after deep watering, you’re likely dealing with pest damage rather than drought stress. To check for grubs, lift a section of damaged turf. If you find white, C-shaped larvae underneath, that’s your culprit.<\/p>
