Here are 5 effectives steps on scarifying your lawn, but the help of professional like Earth Development for instance is advised to use.

Step 1 – Fertilize

So that your lawn survives scarifying well and can recover more quickly, it is essential to strengthening it beforehand. The easiest way to do this is with fertilizer. If you want to scarify in spring, you should wait for the soil temperature to be correct, shorten your lawn to about four centimeters and then fertilize it.

Step 2 – Shorten The Lawn

Once two weeks have passed, it’s time to trim your lawn again, this time to three inches. Short stalks will make it much easier for you to push your scarifier over your meadow. Scarifying is also much more effective with a short lawn, as the felt layer is optimally reached.

Step 3 – Adjust The Scarifying Knife

When it comes to scarifying, less is more. Even if the layer of felt on your lawn is about an inch thick, your scarifier does not have to penetrate completely. On the contrary – scarifying is most effective when the sward is scratched. So set your knife to about two to three millimeters.

With a particularly thick layer of felt, you can adjust the knife to up to five millimeters. This has two advantages: On the one hand, it will be easier for you to remove the thick layer of felt. Second, you will injure your lawn closer to the root. This makes sense with a particularly dense layer of the felt because it releases a growth hormone that activates the recovery process. Your lawn will grow back faster and denser – provided you’ve fertilized properly two weeks beforehand.

Step 4 – Scarifying

Here we go! Drive evenly over your lawn and scratch the sward. For best results, walk across your lawn two or even three times: lengthways, diagonally, and across if necessary. This will scratch the felt layer from different directions and ensure you haven’t missed any spots. You must remove the already loose layer and clean your knife before each pass.

Step 5 – Follow-Up Care

Your lawn has now endured a lot and deserves a recovery. The released growth hormones start the regeneration process immediately after scarifying. Use the help of professionals like Earth Development for instance to ensure that your lawn is well equipped to grow back densely with water and fertilizer.


So immediately after scarifying your lawn, feed it with a fertilizer with high nitrogen content. Nitrogen stimulates leaf development and thereby supports the regeneration process. Our spring lawn fertilizer has the right NPK value and ensures lush green grass.


Ideally, you should now distribute fresh lawn seeds.


Immediately round off the aftercare of your lawn with a good shower to avoid drying out. It is essential to water evenly and carefully to not wash away your freshly spread lawn seeds. Fertilizer is also better absorbed in interaction with water and can act more quickly. Reseeding also needs water to bond with the earth and germination. After scarifying, you must water your lawn about twice a day for two weeks to help your lawn regenerate. When it rains, you can be waterless.

Our pulsating lawn sprinklers are ideal for distributing water, especially for injured blades of grass after scarifying. The sprinkler sprays a fine mist over your lawn, which gently settles on your grass without kinking the stalks and straining them further.
