How to Care for Your Lawn During a Drought

Drought can put severe stress on your lawn and make it more susceptible to insect damage and weed invasion. Fighting drought to keep your lawn healthy can be tough, but with the proper knowledge, techniques and help from TruGreen® experts you can maintain a vibrant, lush green lawn you can be proud of.

• Changes in hue. Your lawn may change color from bright green to dull gray or blue-green.
• Footprints. Footprints (or lawn mower tracks) will stay visible in grasses that are too tired to spring upright after they’ve been pushed down.
• Wilting. Grass blades will roll or fold as they lose water content, wilting visibly in the heat.
• Changes in color. As drought stress becomes more severe, your lawn may do more than lose its bright green hue. If you’re asking, “How can I get my grass green during a drought?” you may already be noticing shades of yellow or tan. Once you see tan coloration, your lawn is in a state of drought-induced dormancy—a last-ditch attempt to survive the dry heat by shutting down.

As water becomes limited, your turf grass will give off signs that it’s in need of watering. Learn to spot these warnings so you can alter your lawn maintenance schedule to avoid drought stress and keep your lawn green and healthy.

Stage 1: Early Drought Stress Signs

During the first stage of drought stress, your turf grass will take on a bluish-gray appearance. Take a walk on your lawn and look for footprints left behind, a key indicator of a dry lawn. Lawn care tips in this stage include regular watering to help the turf grass regain its moisture and recover within a day or two.

Stage 2: The Tipping Point

The second stage of drought stress is considered the tipping point because it’s the last stage where regular watering can revive your lawn. It’s also the phase right before all lawn growth stops. During stage two, turf grass growth is slowed and your lawn may appear patchy. This is due to unequal moisture reserves in your soil—some parts have more reservoirs, some less.

Blades of grass start to fold in an attempt to conserve moisture—areas of grass with compacted or poor soil dry out first. Lawn care tips at this stage include regular watering to revitalize the lawn over a period of three to five days.

Stage 3: Pre-dormancy

The preliminary stage to dormancy, the third stage is when your lawn shuts down all—or almost all—growth and begins to ration resources. Your lawn takes on a greenish-brown color. Any mowing during this period can damage the leaves, stems and crowns—from the mower’s wheels alone.

To stimulate recovery, aggressive irrigation or heavy rainfall is needed over a period of several days. When your lawn finally replenishes enough moisture to begin repairing itself, you can expect recovery to take 10 to 14 days if watering returns to normal.

Stage 4: Dormancy

The fourth stage is pure survival mode for your turf grass. There is no effort made to retain greenness above ground—your lawn will be completely brown. Turf will start to thin. Lawn care tips for recovery at this stage include thorough, deep and repeated watering or heavy rainfall for a period of 14 to 21 days. Unfortunately, any sections of your lawn suffering from poor soil may never recover.

The best way to beat drought stress is to stop it from happening in the first place. Here are some steps you can take to help ensure your lawn stays healthy in dry conditions:

Turf that stands about 3.5 to 4 inches tall helps shade the soil and conserve its water. Mow lawns higher for the summer and on a frequent basis so that no more than ⅓ of the grass blade is cut when mowing.

A clean cut blade of grass requires less energy to heal, allowing grass to conserve energy.

Caring for your lawn in the fall and early spring gives you a head start on a healthy green lawn for summer.

If the drought stress issue is past the point of prevention, you’ll need to focus on fixing the problem. Here are some tips for dealing with drought stress:

If you are wondering how to mow your lawn during a drought, you want to make sure you’re mowing high at the first signs of stress. Mowing too close can result in a shallow root system, increasing chances of drought stress. It’s an easy problem to fix if you catch it early.

Don’t mow drought-stressed grass, and walk on it as little as possible. The more you limit traffic, the less wear and tear you’ll inflict on your already damaged lawn. Avoid the temptation to mow off tall weeds that may be outcompeting your turf until the grass has returned to health.

If your lawn is wilting or showing discoloration, water now. Water your lawn 2-3 times a week during a drought, early in the morning to minimize evaporation. Don’t water in the evening or overnight, as this increases the likelihood of attracting disease or pests. If your lawn has not begun to go dormant, you should see green coloration with regular watering.

Have thatch professionally removed

If you notice drought signs, check for thatch—a layer of decaying stems and roots that can build up over time between the surface and the soil beneath.

Heavy thatch can make your grasses more prone to drought stress when grass roots are in thatch instead of fertile soil. Thatch absorbs moisture but dries quickly, leaving grasses prone to drying even after rain. Consult an expert to discuss the proper time and method of thatch removal to ensure a healthier lawn next season.

Fertilization during drought conditions is tricky and potentially harmful if not done right. In some cases, fertilization may be detrimental to your lawn and cause further damage if applied without the proper moisture. This is why you should leave it up to the experts to determine the right solution to combat drought stress, tailored to your lawn and environment, which does not always include fertilization. Our TruGreen experts select from a range of formulations to provide the proper nutrients for the state of your lawn and seasonal conditions such as drought. As drought conditions subside and moisture levels improve, your lawn will recover more quickly if properly fertilized.

TruGreen’s targeted solutions include treatments specially designed to treat drought stress. When you sign up for a TruGreen lawn plan, a specialist will assess your lawn to determine if it is getting enough moisture. If this examination reveals your grass is suffering from drought, your specialist will provide recommendations on proper watering techniques and may further tailor your plan to manage the effects of moisture deprivation.
