How to Keep Your Grass Green in the Summer Heat

Do you long for the lush spread of green lawn you’d find on a golf course, but don’t know how to make that happen in the summer heat? This article has all the right info to help you bring that vision to life. Follow these tips for a gorgeous, heat-hardy lawn this summer. 

If you want to achieve that dazzling emerald ground cover, an effective lawn care routine is essential. You can make a project of it, or hire a lawn care expert to treat yourself- and your yard. Here are the most critical steps for good lawn care in the heat.

When to Water

The perfect time for watering your lawn is early morning, preferably between 5 and 8 AM. This is typically the coolest part of the day, as the ground has cooled overnight and hasn’t yet absorbed any heat from the morning sun. That means the cool ground can fully absorb the water.

If you water manually or set out a hose-connected sprinkler system, watering super early may not be ideal for your schedule. But if your lawn has a below-ground irrigation system, it’s easy to schedule an early watering time.

For some, neither of these is a viable option due to busy schedules. If that’s you, aim for early evening after the sun has set. Once again, this allows the ground to soak up as much water as possible without risking evaporation due to hot soil or direct sunlight. 

How Often to Water

In hot weather, grass stays its greenest with a thorough watering schedule. However, watering more deeply can be just as effective as frequent watering, if you’re on a restricted irrigation schedule. Deeper watering is when you water for a longer period, giving it a chance to sink more deeply into the soil.

Saturated topsoil is more likely to hold moisture rather than losing it from heat-induced evaporation. Sprinkler systems are time-savers, but a hand-held sprayer will ensure you’re reaching dry spots and hard-to-reach corners of your yard.  


Grass needs nutrition to thrive, specifically in the summer when the longer days prompt accelerated growth. May is generally the best time use weed control and fertilizer products, as this is the peak growing season for grass and other plants in our region. But it’s also not too hot to risk causing chemical burns from the products.

Pest Control

The insects and lawn diseases that threaten your the health and beauty of your yard are more active in the heat. Be sure you’re monitoring your grass for irregularities that might indicate a problem. 

The most common irregularity to look for brown spots that don’t green up after a bit of extra hydration. In this case, they’re likely caused by insects or fungus.  If you’re facing this issue, it’s time to call in expert to check for pests or fungal disease, so they can provide the proper treatment. 

Use a Higher Setting on Your Mower

Keeping your grass cut to 3 inches, rather than the standard 1.5 inches, has a couple of benefits. Your lawn will stay soft and lush looking with a bit of extra length. Additionally, the longer blades provide a denser shield for your root system. This offers a bit of added protection against drying out from the summer heat.

Outdoor pets, romping children, and large objects (such as a play fort) can eventually damage your ground cover. But you can revive a trampled turf with a method called overseeding. This is when you sprinkle fresh seedlings over a dry patch of lawn to promote new growth. If you use this method, be sure you water regularly as the seeds germinate. 


  • Water in the early morning or late evening to decrease evaporation, allowing your lawn to soak up as much hydration as possible.
  • Watering deeply is more important than watering frequently. If your ground cover is soaking in about an inch of water per week, this is generally sufficient.
  • A higher setting on your lawn mower allows your grass to create its own shade coverage, further decreasing any moisture loss in the heat of the day.
  • Overseeding is an effective way to counteract the damage of heavy lawn traffic from pets, parties, and children.

Follow these heat-friendly hints, and you can enjoy a bright green bed of grass all season long. Be sure you visit TLC’s service page to find out how we can help keep your lawn looking lush year-round.
