Dethatching As Part Of Lawn Care


When prevention fails, the solution lies in dethatching. “Dethatching” a lawn refers to the mechanical removal from a lawn of a thatch layer that is too thick. Dethatching is not nearly as big a part of lawn care as is mowing. In fact, some homeowners may never need to dethatch the lawn. Some types of grass simply are not as susceptible to thatch build-up as others. For example:

  • While Kentucky bluegrass is one of the cool-season grasses prone to developing too much thatch, tall fescue grass is far less susceptible.
  • Among the warm-season grasses, you are more likely to have to dethatch Bermudagrass than zoysiagrass .

But when thatch does become a problem in a lawn, you should not overlook the importance of dealing with it, because the long-term health of your grass hinges on your finding a solution. The solution can take either of two forms: dethatching or core aeration.

Dethatching Vs Core Aeration

Of the two solutions, dethatching is certainly preferable to core aeration because core aeration requires a mechanical device. Unhappily, you may not have a choice. The severity of the situation determines which solution is implemented. Dethatching is for mild cases. You will know afterward that it worked if your grass starts looking better the following year.

If grass health does not pick up, that could mean that you have a more severe case. Core aeration may be necessary for your lawn. It is best performed in fall. If you have badly compacted soil, that is another reason to aerate your lawn.

You have three options when it comes to core aeration:

  • Hire a lawn service to do the job.
  • Rent a core aerator.
  • Buy an aerator.

The average homeowner should be able to either hire a lawn service or to rent a core aerator. When it comes to buying, not only is cost an issue but so is storage. Dethatching a lawn by means of a core aerator is probably not going to be a yearly task. Whenever it is not in use, this large piece of equipment will be taking up space in your garage or storage shed. An exception might be made if you own a tractor or a riding lawn mower because you can buy an attachment for these machines that will allow you to aerate your lawn.

If you are not physically up to the job, do not live near a rental center, or just plain do not like gadgets very much, it might make sense for you to choose to hire a lawn service to do this work. Otherwise, renting is a great option.

How Often Should You Dethatch Your Yard

  • Kentucky bluegrass should be dethatched every couple of years either in the spring or early fall.
  • Bermuda grass should be dethatched every spring just as soon as new growth appears.
  • Tall fescues and Rye grass should dont require routine dethatching. Dethatching these grass types is appropriate when you are overseeding to allow for better seed to soil contact.

What Is Thatch What Problems Does It Cause

Thatch is every single leave, root, and crown of dead grass that stays on top or between the grass and the soil. Because its dead, this grass usually looks brownish, making the grass look duller than usual.

Thatch, however, is not necessarily harmful. It gives more bounce to the grass and often makes it look fluffier which is ideal. Also, it insulates the grass and keeps it safe even in extreme temperatures. So you can say thatch is sometimes beneficial.

But when it starts growing too much and the grass doesnt look green anymore then it is problematic, to say the least.

Because thatching is dead grass leaves, rhizomes, roots, and stolons it builds up to a thick layer. And this often happens when the organic part of the grass starts decomposing faster than the grass itself grows.

Thus, the grass gets covered with this dead organic matter, which turns vibrant green grass into brown & dull one. When this happens, you may not like the results at all.

Why? Easy it can cause problems like these:

  • Makes it easy for fungi and insects to appear
  • Increases overall humidity in the grass body which could cause diseases
  • Prevents grass from growing as it limits access to sun, air, water, and nutrients
  • Makes the grass look brownish and disorganized
  • Damages the grassroots which could cause permanent growth issues

How Can You Dethatch Your Lawn

If youre noticing an excessive amount of thatch in your lawn, its time to take action. Thatch is a layer of dead grass, roots, and other organic matter that builds up over time.

After dethatching, your lawn will be more susceptible to drought and heat stress. Be sure to water deeply and regularly during hot, dry weather. You may also want to fertilize your lawn to help it recover from the stress of dethatching.

Dethatching is an important part of lawn care. By removing the thatch from your lawn, youll allow water, oxygen, and vital nutrients to reach the roots of your grass. This will result in a healthier, more vibrant lawn.

Final Thoughts And Tips On Lawn Dethatching

Lawn dethatching may seem like something you dont have to do, but for most homeowners it is vitally important.

If you care about having a lawn full of healthy grass, free from disease and insects then dethatching is something to think about. Dethatching can definitely be done by yourself, but if you have neglected your lawn, and the thatch layer is over 2 inches thick, you may want to consider hiring a professional. Its a lot of work, and if you have the money, getting someone to dethatch and remove the dead grass will save you a lot of time and back strain.

You may need multiple sessions if you have an excessive buildup of thatch, and you must remember not to remove too much at once or you will disrupt the roots. If you have a large thatch problem or seem unsure of what to do, your local lawn professional or garden center can help you make the right decision.

What Is Thatch On Lawns

When most people think of grass, they think of the long, graceful blades that stick out of the lawn. Well, thats only about half the story that grass has to tell. Grass also has below and at-ground level parts, like the crown, rhizomes and roots that help it stay healthy and spread horizontally across the ground. Although the grass blades, which are basically leaves, decompose easily, these other structures do not.

Over time, the other parts of your grass plants can build up into a spongy layer between the grass leaves and the soil. This is the thatch. A small amount of thatch is pretty normal for lawns, but too much and you risk creating a situation where water and oxygen have trouble penetrating to the grass roots, or in severe cases, roots are only anchored in thatch, making it hard for the grass to thrive and even harder to execute any on-trend landscaping ideas.

When And How Often Should You Aerate Your Lawn

Aeration of lawn doesnt have a specific number of times it can be done in a year. Neither does it have a specific date.

There are only two factors that determine when and how often you can aerate your lawns:

  • The nature of the soil
  • The period.

You can aerate lawns once in a year if the nature of the soil is sandy soil. The aeration will only take place during the springtime.

For clay soil, you can aerate your lawn 2 4 times in a year. This number of times will enable the lawns to receive proper water, air, and nutrients to aid their growth.

You can also aerate your lawns during rainfall if there is no tender grass. Because aerating during spring might damage the tender grass roots.

Aerating during the spring will create enough time for the thatch to decompose overtime.

Especially when the spring is almost coming to an end. This process is mainly done to give the lawns more nutrients.

Another method of aeration is before the temperature reaches 55 degree celsius during the spring period. During this period you will be able to pull enough weed in your lawns.

If youre in the north, you can aerate your lawns during the early fall, while in the south you can aerate during the mid-spring to the early summer.

As previously mentioned, a small amount of thatch can be good. Be sure to check your thatch layer before you decide to dethatch. You can do this by digging up a small amount of your lawn grass and soil. Then measure your thatch. If your thatch is more than an inch, itâs time to dethatch.

However, like most lawn health initiatives, the timing must be right. You should try to dethatch your lawn around your grassâ peak growth time. When your grass is growing, it helps your lawn to recover faster from dethatching. For cool season grasses, this is going to be early spring or early fall. For warm-season grasses, itâs best to dethatch in late spring through early summer.

What Is The Best Way To Dethatch My Lawn
