Turn Sunburnt Grass Green Again (5 Proven Solutions)

Does your lawn have small areas of brown patches? Or is your yard turning yellow by the day?

If your area is experiencing intense heat, you might have a sunburn problem in your hands. 

Extensive exposure to sun rays can damage your grass. If you don’t address the issue quickly, it can end up killing your beautiful grass. 

While it may seem like there’s nothing you can do to protect your yard from the sun, that's not entirely true. 

Just by following good lawn care practices, you are already increasing your lawn’s chances of thriving during intense heat.

In this article, Purple Care lawn experts share 5 proven solutions for turning brown, sunburnt grass back into a green, lush lawn. 

Identifying Sunburnt Grass: How Does It Look Like?

Excessive heat and humidity can be bad for some grass types, leading to diseases and scorch. 

Extensive hot days can burn your grass. How can you identify grass sunburns? They look like yellow or brown (dead-like) spots. 

If your lawn is suffering from heat stress, it will quickly start losing its verdant color and become hay-like. As the problem continues, you may notice the dried grass disappear, leaving bare patches through your lawn. 

Why Did My Grass Get Sunburned?

Just like your skin tans or burns when exposed to sun rays, the same happens to your grass. 

The problem is that while you can use sunscreen or stay in the shade to protect yourself from the sun and heat, your lawn doesn't have that luxury.

Intense heat and extensive summer sun exposure are behind your sunburnt grass. 

However, some yards are more prone to getting sun-scorched. These are 3 factors that increase the likelihood of your lawn getting sunburnt: 

  • Yard exposed to full sun: If you don’t have any trees providing some shadows, some grass types can experience sunburn. You might notice that grass protected by the sun for at least some time looks healthier.  
  • You have compacted soil: If your soil is too compacted, water won’t be able to penetrate it and reach the grassroots. 
  • You are mowing too low: This is a common mistake that can cause serious consequences for your lawn. The shorter your grass, the shallower the root system tends to be, which reduces its chances of surviving through intense heat periods.

Will Sunburnt Grass Grow Back?

Will your grass return to its lushes self?

If your grass only suffered a mild scotch, it will grow back in a few weeks.

However, if the problem worsens and the burn is too intense, it can kill your grass, leaving a bare patch in its place. 

Turn Your Grass Green Again With These 5 Proven Solutions

To prevent the heat and sun from killing your grass, you must act quickly. 

These are 5 proven ways to bring your grass back to life after getting sunburnt: 

Water Your Lawn—The Right Way

Is there a right way to water your lawn? You bet there is!

Abundant but less frequent watering is the way to go. 

Depending on the rain levels, 2 to 3 times a week is enough to keep your lawn moisturized and healthy. 

Water in the morning or night to avoid evaporation. Intense evening or afternoon heat causes water to evaporate too quickly before it penetrates the soil and reaches the grassroots. 

Add Nitrogen and Fertilizer

Did the heat already burn your grass, leaving dead patches?

Don’t worry. You can help your grass repopulate that dead spot by nurturing it with nitrogen and a good fertilizer. 

The nutrient boost will help grass grow faster and cover dead patches.

This method is more effective for lawns with small spots of brown or dead patches. If your lawn has a large area severely damaged, you might be better off reseeding. 

Make sure to choose a nitrogen fertilizer suitable for sunburnt grass. 

Hire Lawn Aeration

Aeration is one of the best lawn care services you can hire to reawaken burnt grass.

Remember how we mentioned compacted soil puts your grass at risk of sunburning? Well, aeration can prevent or solve that issue. 

Lawn aeration involves plucking small holes into the soil to loosen it. This allows water and air to flow seamlessly through the soil, reaching and nurturing the grassroots. 

Proper air and water flow reduces the risk of the heat harming your lawn and helps your grass recover faster from sunburns. 

Overseed Your Lawn

Has your yard suffered severe sunburn? Or are there too many bare patches on the lawn?

In such cases, the best is to overseed. 

Not all grasses recover from severe sunburn. And even if they do, they might grow thinner and not as healthy as they used to be. 

Schedule overseeding services in the fall or spring to help your lawn grow dense and lush. 

Give It Time

Our last advice is to give it time.

We know how frustrating it can be to see your beautiful lawn covered with brown burnt patches. 

But if you go crazy trying to fix it quickly, you may cause more harm. Avoid over-watering your lawn or over-fertilizing (it can cause further burns). 

Time is the best remedy for scorched grass. Follow the tips from this guide and allow your grass time to grow back and cover your beautiful lawn.
