What is a lawn scarifier

How does the scarifier work?

Scarifiers either work on gasoline or electricity. We suggest you use the scarifier on gasoline if you have a large lawn.

Otherwise, a small lawn can be handled with an electric scarifier.

Moreover, read the instructions written on the modal. It will paint a clear picture for you of how to use the scarifier.


Now we will know what steps are taken during scarification.


Steps of scarification:

For a smooth and effective scarification, you need to follow the procedure step by step.


  • Kill the moss and remove debris.

The first step is to apply moss killer. Moss and other debris

stop the water from entering the turf. This makes topsoil

        hard. And you can understand that hard turf would never

allow water and nutrients to reach the roots of the grass.


  • Mow the lawn on low settings:

Next, you need to mow the lawn on a low setting. Why the low setting? Because this will cut the maximum amount of grass for the scarifier to get through the soil. Moreover, this will make it easy for you to collect the grass.


  • Now scarify the lawn in a high setting:

Setting the scarifier at high would help you gather maximum moss and thatch. Afterward, you can do it on low when doing repetition.


After you have finished the scarification, you will see yellow patches or find the soil disoriented. There is nothing to be worried about. It’s just a normal thing, and after a few days, you will find your lawn lush again.


  • Use rake for remainders:

Although repeated applications of scarifier can remove all the stuff, you may still find leftovers. To get rid of these leftovers, just grab a rake and pay a visit to the lawn. Now you’ve done a great job.


  • Spread the topsoil:

 This is the best time to spread the topsoil. Because it will interconnect with the lower layer of the soil, making it useful for the fresh growth of the grass.


  • Spread the grass seeds:

It’s better to spread the grass seeds at this point because scarification may create some patches in the grass. These new seeds will give a boost to the regrowth of the grass.


That’s it. This is all you need to know about the scarification process.


How many times should a lawn be scarified?

Usually, you should use a scarifier twice a year. Moreover, it also helps in the aeration of the lawn. The small holes during the process allow water and other nutrients to go down to the roots.
