Late-summer lawn rescue: Helping your lawn beat the heat

If you've looked out at your lawn lately and wondered what happened to all that green, you're definitely not alone.

This summer has brought prolonged stretches of intense heat across Southern California, and for many homeowners, it feels like the heat wave has simply become the new normal. Even well-maintained lawns are showing signs of stress as they battle scorching temperatures, dry conditions, and relentless afternoon sun.

While you can't control the weather, there are several simple steps you can take to help your lawn survive the remainder of summer and bounce back when cooler temperatures finally arrive.

Raise your mower height

It may seem like mowing shorter would help, but the opposite is true. Keeping your grass a little taller allows the blades to shade the soil, helping retain moisture and encouraging deeper, healthier root growth. Just remember not to remove more than one-third of the grass height in a single mowing.

Water deeply and early

Instead of watering every day, aim for deep watering sessions during the early morning hours. This gives water time to soak into the soil before the afternoon heat causes rapid evaporation. Deep watering also encourages roots to grow downward, making your lawn more resilient during hot weather.

Hold off on fertilizing

When temperatures are consistently high, your lawn is already working hard just to survive. Applying fertilizer during periods of extreme heat can place additional stress on the grass and may even cause burning. Save major fertilizing for early fall when temperatures begin to moderate.

Check your irrigation system

A broken sprinkler head or clogged nozzle can leave sections of your lawn thirsty without you realizing it. Take a few minutes to inspect your irrigation system and make sure every area is receiving even coverage. A small repair today could prevent larger brown patches later.

Give stressed areas a break

Heat-stressed grass doesn't recover as quickly from heavy foot traffic. If possible, avoid repeatedly walking across the same worn areas until the weather cools. Giving your lawn a little breathing room now can make a noticeable difference in its recovery.

Don't panic over brown spots

Brown grass isn't always dead grass. Many Southern California lawns naturally go dormant during prolonged periods of extreme heat to conserve energy. As cooler temperatures return and watering becomes more effective, healthy lawns often begin greening up again.

Looking ahead to fall

While August can be one of the toughest months for Southern California landscapes, it's also the perfect time to start thinking ahead. Cooler weather is just around the corner, bringing ideal conditions for fertilizing, repairing bare spots, and encouraging fresh growth.

With a little extra care now, your lawn will be in a much better position to recover and thrive throughout the fall season.
