What Is Dethatching?
Dethatching your lawn is the process of removing excess thatch from your grass. Thatch is a layer of living and dead stems, leaves, and roots. This organic matter forms between the grass and soil, and a normal amount can help keep your lawn healthy. However, too much thatch can prevent water, air, insecticide, and fertilizer from reaching the soil, which can cause serious problems for your lawn. Consult a local lawn care service about whether dethatching is right for your lawn.

Pros of Dethatching Your Lawn
Consider the benefits of dethatching your lawn.
Promotes Lawn Health
Since thatch acts as a barrier between the grass and soil, a layer of thatch that’s too thick can restrict the movement of air, water, and nutrients into the roots, which negatively impacts soil health. Dethatching can improve lawn health by improving drainage and reducing compaction.
Keeps Pests Away
A thick layer of thatch provides the ideal habitat for insects to lay eggs because of its high humidity when wet and abundant food source of organic matter. Removing unnecessary thatch can deter lawn pests, boosting your lawn’s health and keeping these pesky critters off your grass.
Prevents Grass Diseases
Thatch is an ideal breeding ground for fungal pathogens because of its moist and humid condition. Pathogens like mold and fungi can lead to grass disease. Dethatching can help to fight against grass disease by removing the conditions that are easily susceptible to disease.
Cons of Dethatching Your Lawn
Consider some downsides of dethatching your lawn.
Costly
Dethatching can be an expensive lawn maintenance project, depending on the size of your yard and the level of thatch. The cost of dethatching ranges from $100 to $700 on average. Your exact cost will depend on several factors, including whether you hire a lawn care professional, the size of your lawn, and the cost to rent or buy dethatching tools.
May Disrupt Beneficial Bacteria
Though bacteria can get a bad reputation, some of them are healthy and work to keep your lawn in tip-top shape. Dethatching can disrupt the soil’s natural microbial activity and pH levels, depriving your lawn of essential nutrients and organic matter. Consult a lawn care professional about testing your soil to confirm dethatching is the right next move for its health.
Risk of Lawn Damage
Dethatching can damage your lawn if it’s done improperly or at the wrong time. For example, you should avoid dethatching while the grass is dormant or stressed as it can cause permanent damage. So if you’re doing a DIY job, make sure to use dethatching tools correctly or hire a lawn care professional to ensure your lawn stays safe.
Alternatives to Dethatching
While lawn aeration doesn’t replace dethatching, it can be an alternative project that puts less stress on your lawn. Aeration helps to loosen compacted soil, making it easier for air and water to reach the roots.
If your lawn doesn’t have much thatch buildup, you may be able to skip dethatching altogether and opt for aeration instead. Most lawn care pros will recommend performing both aeration and dethatching to maximize your lawn’s health.
Should You Dethatch Your Lawn?
While dethatching has its advantages and disadvantages, it plays a vital role in maintaining a lush, healthy lawn. As a general guideline, consider dethatching if your thatch is more than half an inch thick. For optimal results, you’ll want to dethatch during the growing season, not when your lawn is dormant or stressed.
If you’re unsure whether or not dethatching is best for your lawn, hire a local lawn care service. A lawn care pro can help you come up with a quality lawn care plan and perform any needed services, including dethatching.
Frequently Asked Questions
To determine whether your lawn needs dethatching, use a garden trowel or spade to dig up a small chunk of your grass and soil. Examine the spongy layer between the grass and soil, otherwise known as thatch. If the layer of thatch is more than ½-inch thick, consider dethatching to protect the health of your lawn. Make sure to check several areas of your lawn, as the amount of thatch can vary.
Aerating and dethatching are two different processes that play important roles in maintaining the health of your lawn. Aeration helps to break down compacted soil and improve soil drainage. Dethatching removes thatch buildup which helps nutrients to reach the soil. Hire a local lawn care service to determine whether aeration or dethatching is the best next step for your grass.
