What is Thatch?

Thatch is a layer of primarily dead grass tissue that you can see between the healthy grass and soil and roots. It can often appear after long and cold winters with a lot of snow when parts of turfgrass that are resistant to decay, start to produce debris quicker than they get to break down.

Having some thatch can be beneficial as it contributes to the resiliency and health of your lawn. It provides insulation against extremely hot or cold temperatures. Therefore if you notice a thatch layer about half-inch or less thick – there’s no need to worry.

However, if there is too much of it, you should think about dethatching the lawn; otherwise, a very thick layer of thatch can cause significant damage to the roots. Which is where the power rake or dethatcher comes to your rescue.

A lot of people confuse these two, thinking they are the same. However, although they are indeed similar, there are plenty of differences between power rake vs dethatcher.

Power Rake vs Detchatcher: The Differences

A power rake is a powerful machine with mechanical flails. It is used not only to take the thatch out of the lawn but also to dig it from deep under the ground. 

The power raking lawn is a pretty aggressive process, and the machine it is done with is about the same size as the push lawnmower. 

Thus, if you see that you have a lot of thatch then use a power rake vs dethatcher. After that, you need to mow the lawn and pick up the thatch along the way.

And what is a dethatcher? Also known as a lawn scarifier, this is a machine that is used to remove thatch from the lawn. There are two types – motorized dethatchers and others that are attached to lawnmowers or gardening tractors. 

Plus, if you compare power raking vs dethatching, it is easy to notice that dethatching is a way less aggressive process and a much better option for smaller lawns. Moreover, with the right machine, it would also be a lot faster than power raking.

What is Power Raking?

As we mentioned already, power raking is an excellent way to remove the debris and thatch after winter, and it is the best way to get rid of thatch on the bigger lawns. 

However, it is an aggressive process, since the power rake usually involves sharp blades that are designed to slice the thatch and not rip it out. Thus, before you use a power rake it’s best to acquire some skill and knowledge, and it is definitely not the best method for beginners. Since if not done well, power raking can cause extensive damage to your lawn.

How to Use Power Rake?

To use the power rake you have to:

using power rake
  • Make sure that there is more than ¼ inch of thatch on the lawn.
  • Set the deck high and turn on the machine
  • Make one pass to see how much dead grass it removes at one go.
  • Gradually lower the deck and continue to work across the lawn.
  • Pick up all the remains with the mower or rake.
  • If necessary, go once more over the lawn.
  • Remove all remaining debris.

When to Power Rake?

Now, when it comes to types of grass that grow in colder regions, you should do it in spring or early fall. And if you are living in warmer areas, it is better to power rake in spring or early summer.  

Keep in mind that power raking necessarily damages some of the healthy grass as well. Therefore you should give your grass enough time to recover.

How Often to Power Rake?

The general answer to this question is once a year. The best time, as you could notice, differs depending on the type of grass and climate in your area. 

Now, some people have asked about power raking or dethatching vs aerating. Suppose you assess that there is not enough thatch and, therefore, no need to power rake or dethatch in a particular year, we still recommend that you aerate. It will allow the grassroots to get all the nutrients, air, and water to reach the grassroots.

What Is Dethatching?

In order to choose between power rake vs dethatcher, you must also understand what dethatching is. 

Similar to power raking, it is the process of removing lawn thatch and debris. Dethatching is done by a machine that can be manual but also run on gas and electricity.  Using a dethatching blade vs power rake is less aggressive than power raking. However, it can still be harmful to the lawn if not done carefully and at the right time.

When to Use a Dethatcher?

First, you need to understand when to dethatch. If there is just a thin layer of thatch, as we mentioned, it is beneficial for the lawn and shouldn’t be removed. However, if the thatch layer is over ½ inch, then you should use a dethatcher

Also, beware that it is best to dethatch the lawn in the fall as there is no risk of damaging the healthy grass. It is also best not to use a dethatcher in early-mid spring, since it will rip and tear the dormant turf, preventing it from recovering from injuries caused by cold weather.

How Often Should You Dethatch Your Lawn?

Same as with power raking, generally, every lawn should be dethatched once a year or when you notice that the thatch layer becomes thicker than ½ inches. 

To make sure, simply put your finger in the grass and see how deep is the thatch layer. If you have cold-season grass, it is best to dethatch it in fall, and for warm-season grass, the best time is early spring.
