We have all been there, your lawn is looking great. The grass is thick, green, and feels great beneath your toes. 

But, seemingly out of nowhere, your lawn becomes brown. 

What happened!? 

So, now you want to know: "How can I prevent my lawn from turning brown in the summer heat?"


Good news! 9 times out of 10, a brown lawn caused by summer heat is preventable. 

And the solutions are rather simple. 

Below you will find out how you can prevent your lawn from turning brown when summer heat rolls in. 

Raise deck height in summer

Mow Your Grass Higher in the Summer

As the summer heat rolls in, your lawn needs to hold on to as much water as it can. And cutting your lawn too low will reduce it's ability to retain moisture. And less water will be contained in the grass itself.

While there are other things you can do to ensure that your lawn itself retains more moisture, the best way to keep more water in the lawn is to simply raise your cutting height.

So, as summer heat rolls in, raise your cutting height an inch or two. 

Get this while your lawn may be healthy at 2 to 2.5 inches in spring and fall, your lawn needs to be about 3 to 4 inches in the heat of the summer to be better equipped to survive drought.

Proper Watering Is Essential

Look this one is truly no secret, another great way to prevent your lawn from turning brown in the summer is to water it regularly. 

Of course, in some cities, you simply are not allowed to use enough water to do so. If that's the case you really need to focus on letting your lawn grow taller and utilizing the following techniques to ensure your lawn holds as much water as possible. 

Pro Tip! Watering deeper and less often will create deeper roots that are accustomed to drought. The deeper your roots can reach, the more water they potentially have access to. And if you have taken the steps below, your grass will have plenty of water to drink from.

Syringing the Lawn

Syringing is the act of briefly watering in the middle of the day to cool the lawn down. 

Simply turn on your irrigation system for 5 minutes around the hottest part of the day. While this idea contradicts the general recommendations for watering, the idea is not to water the lawn, but to cool it down. 

However, the verdict is still out on whether syringing is effective or not

Pro Tip! If you are in an area with strict water usage limits, you may want to consider using rain barrels to store up water for those hot summer days when your lawn is in desperate need of water.

Humates Help Hold Water in the Lawn

Humus or humates are the organic material that makes up your soil and can act like a mulch for your lawn. Allowing the grass to grow freely, all the while helping to retain moisture

Further humus can house beneficial bacteria and fungi that can allow a lawn to be more drought tolerant. 

A good topdressing with compost will help add humates regularly to the lawn. You can compost your grass clippings and kitchen scraps to make a great top-dressing mix that will add plenty of humates to your lawn. 

Pro Tip! Organic fertilizers will feed microorganisms. Unlike synthetic fertilizers which will often kill them, and can lead to poor nutrient uptake and less drought-tolerant grass.
