Summer Lawn Stress? Here's How to Keep Your Grass Green and Healthy Through the Heat

Hot summer days are here — and your lawn is feeling it. Brown patches, thinning grass, and wilting blades are all signs of summer stress on your turf. But don’t worry — with the right care, you can keep your lawn green and lush even during July’s heatwaves. Here's everything you need to know about summer lawn care, including watering tips, mowing strategies, and more.

1. Water Deep, Not Often

Many homeowners water their lawn daily — but that's a mistake.

The key is deep, infrequent watering. This encourages deep root growth and better drought resistance.

✅ Tip: Water early in the morning (between 5–9 AM) to minimize evaporation and avoid disease.

✅ How much water? Aim for 1 to 1.5 inches per week, including rainfall.

2. Mow High and Mow Smart

Cutting your lawn too short in summer is one of the fastest ways to damage it.

Set your mower to 3–4 inches high.

Taller grass shades the soil, retains moisture, and protects roots.

Never remove more than 1/3 of the grass blade at a time.

✅ Bonus Tip: Keep your mower blades sharp — dull blades tear the grass and increase stress.

3. Skip the Fertilizer (For Now)

Fertilizing in extreme heat can burn your lawn. Hold off until late summer or early fall when temperatures cool and the grass can recover.

4. Watch for Weeds and Pests

Heat-stressed lawns are more vulnerable to weeds like crabgrass and pests like grubs.

Hand-pull weeds or use spot treatments for isolated problems.

If you suspect grubs (spongy turf, brown spots that pull up easily), contact a lawn care professional for treatment options.

5. Consider Overseeding in Late Summer

If your lawn has suffered damage this summer, plan ahead. Late August to early September is the best time to overseed and repair bare spots. Start prepping now so you're ready when the time comes.

Final Thoughts

Summer can be tough on your lawn, but with the right strategies, you can maintain a green, healthy yard that looks great all season long. And if you're feeling overwhelmed or short on time, let the pros handle it!
