1. Water wisely for deep root hydration
Watering at the optimal time of day is essential for efficient lawn hydration and minimizing evaporation losses, ensuring your grass gets the moisture it needs to thrive in Houston’s intense summer heat.
- Best time to water is early morning before 10 AM, when temperatures are cooler and the sun isn’t at full strength.
- Water deeply two to three times per week rather than shallow daily watering to promote stronger root systems.
- Ensure soil moisture reaches six to eight inches deep to encourage deep-root growth and better drought resistance.
Why This Works
- Reduces evaporation, allowing more water to reach the roots where it’s needed most.
- Encourages deeper, stronger roots, making grass more resilient to heat and drought conditions.
- Helps prevent fungal growth and lawn diseases, which thrive in overly moist, humid conditions when watering is mistimed.
2. Mow high to protect your grass from heat stress
Many homeowners cut their grass too short in summer, leaving it more vulnerable to heat stress and water loss.
- Set mower height to 2.5-3.5 inches for St. Augustine, Bermuda, and Zoysia grass
- Taller grass shades the soil, preserving moisture and preventing weeds
- Deep roots make your lawn more drought-resistant
Pro tip
Never remove more than one-third of the grass blade height in a single mowing session to avoid shocking your lawn.

3. Fertilize with caution to avoid burning your lawn
Fertilization is crucial for lawn health, but applying the wrong type of fertilizer at the wrong time can do more harm than good in extreme heat.
- Avoid fast-release or liquid fertilizers during heat waves, as they can burn grass
- Use slow-release fertilizers that gradually break down over three to ten weeks, providing steady nutrients without overstimulating growth
Why slow-release fertilizers work better in summer
- Prevents lawn burn caused by excess nitrogen uptake
- Encourages even, sustainable growth without stressing the grass
- Reduces the need for frequent watering, keeping your grass healthier with less effort
4. Mulch grass clippings instead of bagging them
Instead of bagging grass clippings, leave them on your lawn as a natural mulch to retain moisture and improve soil health.
- Reduces evaporation, keeping the soil cooler
- Recycles nutrients, acting as a natural fertilizer
- Improves soil structure, reducing compaction over time
Pro tip
Use a mulching mower to finely chop grass clippings for faster decomposition and better nutrient absorption.
5. Avoid mowing during the hottest part of the day
Mowing during peak afternoon heat can stress your lawn and cause grass blades to lose moisture too quickly.
- Mow in the early morning or late evening when temperatures are lower
- Prevents heat shock to freshly cut grass blades
- Reduces stress on the mower operator, keeping you safe from extreme heat
Additional tip
Sharpen mower blades regularly—dull blades tear the grass instead of cutting it cleanly, making it more susceptible to moisture loss and disease.
Additional lawn care strategies for extreme Houston heat
Proper lawn care goes beyond watering and mowing—taking proactive measures against drought stress, pests, and changing weather conditions ensures a healthy, resilient lawn throughout the summer.
Watering Schedule and Technique
- Watering too frequently can weaken root systems. Instead, water deeply two to three times per week to encourage strong root growth.
- Adjust watering based on rainfall and local restrictions to prevent overwatering and runoff.
Preventing Lawn Pests and Grubs
- Grubs and other pests can severely damage lawns by feeding on grassroots, leading to brown patches.
- Apply preventative grub control treatments in early summer to stop infestations before they spread.
Planning Around the Weather
- Before a heat wave, water deeply to help your lawn retain moisture and withstand high temperatures.
- Limit foot traffic on stressed or dry grass to prevent additional damage.
Seasonal Treatments and Natural Lawn Care
- Organic topdressing and aeration improve soil quality and enhance moisture retention during extreme heat.
- Use selective herbicides to control weeds without damaging your lawn or disrupting beneficial grass growth.
