Summer heat can be tough on lawns, especially during extended periods of high temperatures and limited rainfall. Without proper care, grass can quickly turn brown, thin, or stressed. Following the right lawn care practices helps protect your grass, promote deep root growth, and keep your lawn green and healthy all summer long.

Understand How Heat Affects Your Lawn

High temperatures increase water evaporation and place stress on grass roots. Lawns that are shallow-rooted or improperly maintained are more likely to dry out and go dormant. While some browning is a natural defense mechanism, proper care can minimize heat stress and encourage faster recovery.

Water Deeply and Infrequently

One of the most important steps to keeping your lawn green in summer is proper watering.

Best watering practices:

  • Water early in the morning to reduce evaporation

  • Apply water deeply to encourage strong root growth

  • Avoid frequent, shallow watering

  • Adjust irrigation schedules during heat waves

Deep watering helps roots grow deeper, making grass more drought-resistant.

Raise Your Mowing Height

Short grass dries out faster and is more susceptible to heat damage.

Tip:
Set mower blades higher during summer. Taller grass shades the soil, reduces evaporation, and protects roots from extreme heat.

Leave Grass Clippings on the Lawn

Grass clippings act as a natural mulch, helping retain moisture and return nutrients to the soil.

Bonus:
Mulching clippings reduces the need for additional fertilizer and supports soil health.

Limit Foot Traffic

Excessive foot traffic during extreme heat can compact soil and damage stressed grass.

Recommendation:
Avoid heavy use of your lawn during peak heat, especially in high-traffic areas.

Avoid Fertilizing During Extreme Heat

Applying fertilizer during hot weather can burn grass and increase stress.

Best practice:
Limit fertilization in mid-summer and focus on proper watering and mowing instead.

Control Weeds Without Stressing the Lawn

Weeds compete with grass for water and nutrients, but harsh treatments during heat can damage turf.

Tip:
Use spot treatments and avoid broad applications during extreme temperatures.

Improve Soil Health

Healthy soil helps lawns retain moisture and nutrients more efficiently.

Ways to improve soil health:

  • Aerate compacted soil

  • Add organic matter when appropriate

  • Maintain proper pH levels

Improved soil conditions help grass survive summer heat.

Consider Drought-Tolerant Grass Varieties

If your lawn struggles every summer, drought-tolerant grass types may be a long-term solution.

Examples include:

  • Tall fescue

  • Kentucky bluegrass blends

  • Perennial ryegrass

A professional landscaper can recommend the best grass type for your region.

Know When Browning Is Normal

Some grass may naturally go dormant during extreme heat to conserve energy. Dormant lawns often recover when temperatures cool and moisture returns.

Conclusion

Keeping your lawn green during summer heat requires proper watering, smart mowing practices, and reduced stress. By adjusting your lawn care routine during hot weather, you can protect your grass, maintain curb appeal, and support healthy growth throughout the season. Whether you handle lawn care yourself or hire a professional, these strategies help your lawn withstand summer’s toughest conditions.
