Texas droughts are a fact of life in our region. When rainfall disappears for weeks and temperatures push past 100 degrees, lawns suffer fast. St. Augustine and Bermuda grass both go dormant to survive, turning brown and brittle. But with smart watering, mowing adjustments, and realistic expectations, you can keep your lawn reasonably healthy until the rains return.
Water Deeply and Infrequently
Shallow, frequent watering creates weak roots that cannot reach moisture deeper in the soil. During drought, water your lawn once or twice a week at most, applying about an inch of water each time. Early morning is best, before 10 a.m., so less evaporates in the heat. Run sprinklers long enough that water soaks down six inches. You can check depth with a screwdriver pushed into the soil. Clay soil in The Woodlands holds moisture well once it gets wet, so deep watering pays off. If your city or HOA has watering restrictions, follow them. A lawn can survive on less water than you think.
Raise Your Mowing Height
Taller grass shades the soil, keeps roots cooler, and holds moisture better. During drought, set your mower blade higher than usual. For St. Augustine, mow at three to four inches. For Bermuda, two to three inches works. Never remove more than one-third of the blade height in a single mowing. Scalping the lawn in summer heat stresses it badly and opens the door for weeds. If grass grows slowly because of drought, mow less often. Let the clippings fall back on the lawn. They return nitrogen and help the soil retain moisture.
Accept Some Dormancy
Both St. Augustine and Bermuda grass go dormant when water runs out. The grass turns brown but the roots stay alive underground. Dormancy is a survival mechanism, not death. If you cannot water enough to keep grass green, let it go dormant and wait. Dormant grass needs almost no water, maybe a half inch every three to four weeks just to keep roots from dying. It will green up again when rain comes back or when you resume watering in fall. Trying to force green growth during severe drought wastes water and can damage the lawn more than dormancy would.
Skip the Fertilizer
Fertilizing during drought pushes grass to grow when it has no water to support that growth. The result is burned, stressed turf. Hold off on fertilizer until conditions improve. If you fertilized in spring, that is enough to carry the lawn through summer. Focus on water management and mowing height instead. Fertilizer can wait until fall when temperatures drop and rain becomes more likely.
Watch for Pests and Disease
Drought-stressed grass is more vulnerable to chinch bugs, grubs, and fungal problems like brown patch. Check your lawn weekly. Chinch bugs show up as irregular yellow patches that spread quickly in St. Augustine. Brown patch creates circular dead spots. If you see damage that does not match simple drought stress, identify the problem early. Treatment works better when you catch issues small. Healthy soil and proper watering practices give your lawn the best chance to resist pests even under tough conditions.
