Top 3 Summer Lawn Care Tips to Keep Your Grass Healthy During Heat Stress

As summer temperatures begin to rise across Langhorne, PA and Bucks County, we start seeing one of the biggest seasonal challenges for homeowners: heat and drought stress on lawns.

It’s very common this time of year for grass to begin losing color, thinning out, or showing signs of stress as temperatures climb and rainfall becomes inconsistent. The good news? There are a few simple things homeowners can do to help protect their turf during the toughest months of the year.

Here are our Top 3 Summer Lawn Care Tips to help your lawn survive the summer heat and stay healthy all season long.

How Homeowners in Langhorne, PA and Bucks County Can Protect Their Lawn This Summer

1. Water Your Lawn Properly (And Avoid Overwatering)

One of the biggest mistakes homeowners make during summer is watering too often without watering deeply enough.

Your lawn needs water, especially during dry periods, but shallow watering can actually lead to weaker root systems and more stress over time.

For best results:

  • Water early in the morning before temperatures rise
  • Aim for deep watering 2–3 times per week rather than daily light watering
  • Target 20–30 minutes per zone depending on your irrigation system
  • Focus on encouraging deep root growth so your lawn can better handle heat and drought conditions

Deep roots create stronger turf that can better survive stressful summer weather.

2. Raise Your Mowing Height During Summer

As temperatures increase, mowing too short can seriously damage your lawn.

Short grass exposes more of the soil to direct sunlight, causing moisture to evaporate faster and putting unnecessary stress on the turf.

We recommend:

  • Raising your mower deck height during summer
  • Following the 1/3 Rule (Never remove more than one-third of the grass blade at one time)
  • Keeping grass taller to provide shade to the soil and help retain moisture
A taller lawn acts as a natural defense system against summer stress.

3. Continue Fertilizing Through Summer

Many homeowners think lawn fertilization stops once summer arrives — but that’s not true.

Your lawn still needs nutrients throughout the growing season. The difference is that summer applications require a different approach than spring or fall treatments.

Proper summer lawn applications may include:

  • Slow-release fertilizer programs
  • Stress reduction products designed for summer conditions
  • Balanced nutrients that help strengthen turf without forcing excessive growth
Using the right products during summer can make a huge difference in keeping your lawn healthy when temperatures are at their highest.
