Lawn Scalping – Is it Harmful or Helpful for Your Grass? 

Lawn scalping has become a popular technique for many homeowners and landscapers in recent years. However, the controversy surrounding it has also grown. While some believe it to be an effective way of rejuvenating a lawn, others argue that it can cause more harm than good if not done properly. 

At NG Turf, we understand that lawn scalping is a sensitive issue that requires careful consideration. Our experts have researched and evaluated the potential benefits and drawbacks of the technique to provide you with a comprehensive guide on how to do it correctly. 

What is Lawn Scalping?

Lawn scalping involves cutting your grass extremely low to the ground, typically to a height of about 1 inch. The purpose of this technique is to remove the old, dead grass and thatch build-up, allowing new growth to emerge. It can also promote deeper root growth, which is essential for a healthy lawn. 

When is the Best Time to Scalp Your Lawn?

Timing is crucial when it comes to lawn scalping. The best time to scalp your lawn is during the late winter or early spring, just before the grass starts to grow. It is also best to do this when the ground is not frozen and when the grass is dry to prevent damage. 

What Grass Types is Lawn Scalping Recommended?

Lawn scalping is generally recommended for warm-season grasses such as Bermuda and Zoysia grasses. These grasses tend to accumulate thatch buildup, which can cause the grass to become weak, thin, and patchy over time. These grasses also have stolons (above-ground stems) and rhizomes (below-ground stems) that allow them to recover quickly.

However, it is important to note that lawn scalping is not recommended for cool-season grasses (such as bluegrass or fescue) or warm-season grasses that spread by stolons alone (such as St. Augustine, centipede, and bentgrass) as it can cause significant damage to the grass and inhibit its growth. It is always best to consult with a lawn care professional to determine if lawn scalping is appropriate for your specific grass type. 

Benefits of Lawn Scalping

While it may seem counterintuitive to some, lawn scalping can actually have a range of benefits for your lawn when done correctly, from promoting healthy growth to improving its overall appearance.

Removes Debris

First, it helps to remove the dead grass and other debris that can accumulate on the surface of the soil over the winter monthsThis debris can create a barrier that prevents nutrients and water from reaching the roots of your grass, which can lead to a less healthy lawn. By removing this debris, you are allowing your grass to access the nutrients and water it needs to thrive. 

Promotes New Growth

Second, lawn scalping helps to promote new growth. When you cut your grass very low, it stimulates the growth of new shoots and roots. This can help to thicken your lawn and make it more resistant to weeds and other pests. 

Promotes Deeper Root Growth

Scalping your lawn can encourage your grass to develop deeper root systems, making it more resilient to drought and other environmental stresses.

Helps Reduce Thatch Build Up

Finally, lawn scalping can help to reduce thatch buildup. Thatch is a layer of dead grass and other debris that accumulates on the surface of the soil over time. If left unchecked, thatch can prevent water and nutrients from reaching the roots of your grass. By scalping your lawn, you are removing this thatch layer and allowing your grass to access the nutrients and water it needs to thrive. 

Potential Risks of Lawn Scalping

While there are numerous benefits to lawn scalping, there are also potential risks if not done correctly. These include: 

Damage to the Grass Crown

Scalping your lawn too low can cause damage to the grass crown, which can prevent it from growing back. Be mindful of bumpy or uneven areas in the lawn to avoid mowing too low and causing damage.

Leaving the Soil Exposed

Scalping your lawn at the wrong time, such as during the hot summer months, can leave the soil exposed, making it vulnerable to damage and disease. 

Making Lawn More Susceptible to Pests and Disease

If not done correctly, lawn scalping can create a perfect environment for pests and diseases to thrive.

How to Scalp Your Lawn Correctly

Lawn scalping is a relatively easy process that can be done with a lawn mower. Here are the steps to follow: 

Step 1:

Wait until the beginning of the growing season, usually in early spring. This is typically after the last frost of the winter season and when the grass starts to show signs of growth. It’s important to note that scalping your lawn too early or too late in the season can damage the grass and hinder its growth, so timing is key.

Step 2:

Mow your lawn to a height of about 1 inch or less. Be sure to remove all of the debris that is left behind on the lawn.

Step 3:

If you have a lot of thatch buildup, you may need to use a specialized scalping machine to remove it. These machines are designed to cut into the soil and remove the thatch layer.

Step 4:

Once you have scalped your lawn, be sure to water it thoroughly. This will help to promote new growth and ensure that your grass has access to the nutrients and water it needs to thrive. 


Lawn scalping can be an effective way of rejuvenating your lawn, but it is crucial to do it correctly. At NG Turf, we recommend consulting with a professional landscaper to ensure that you do not cause any damage to your lawn. By doing it right, you can enjoy a healthier, more vibrant lawn for years to come.
