The question of why and how to scarify your lawn is not self-evident. It is not necessarily easy to know what a scarifier is and what it is used for, if you don’t have a lawn or if you don’t know anything about gardening.
Why scarify your lawn?

These plants form a barrier to the sun’s rays, air, water and various nutrients that are necessary for the health of your lawn.
To maintain your lawn and provide it with these nutrients, it is advisable to use a scarifier.
There are 3 main categories of scarifiers, which differ in materials, prices, accessories, etc.

The scarifier improves the quality of your lawn and promotes its growth because it is equipped with a roller with teeth, claws or sharp knives.

When to scarify your lawn?
It is recommended to scarify your lawn twice a year: in early spring, after the last frosts, to get rid of winter waste and prepare the lawn for a beautiful summer; and in autumn, just before the first frosts, to prepare the lawn for winter rest.
In order to properly scarify your lawn, it is recommended never to do so when the lawn is too wet or too dry. It is best to mow the lawn, about 2 cm high, then pass the scarifier. Then, the scarifier can easily be adjusted between 2 and 4 mm, in order to avoid tearing off the roots of the lawn.
In order to effectively scarify your lawn, it is best to do it once in width and once in length.
