How To Make the Most Out of Your Scarifier

Whilst it may have a somewhat ominous name, a scarifier is one of the most important garden tools to have in your arsenal, especially if you’re looking to give your lawn a complete makeover.

In this article we will be talking you through some of the best ways to use and maintain your scarifier so you’ll be rolling with the pros in no time!

Scarifiers in a nutshell

A scarifier is a piece of garden machinery designed to cut through your lawn, unlike a lawn mower that only cuts the surface. This helps to remove any moss or other debris that has accumulated and is otherwise challenging to remove using other tools. 

The importance of using a scarifier

Scarifiers are a crucial tool in aerating the soil, thus giving it more room to breathe and proper drainage for rainwater. If debris remains on the surface of the grass, rainwater will not be able to reach the soil which will encourage more moss accumulation as well as having a sodden lawn. 

Scarifiers vs aerators

Scarifying is a much more aggressive process compared to aerators whose function is only to punch holes in the soil, allowing it to breathe and absorb nutrients like fertilisers more effectively. Scarifiers on the other hand dig deep to pull up unwanted debris from beneath the surface of the lawn. 

The best time to use a scarifier

It is widely agreed that your lawn should be scarified twice a year; once in early spring (around April provided there wasn’t too much rainfall) and again at the beginning of autumn (September). It is also important that you do not scarify a lawn that is dormant otherwise you could cause permanent damage. 

Preparing your lawn

Before you bring out your scarifier, you should rake off any moss and other debris on the lawn and apply a moss killer to remove any active moss on the surface. Missing this step means you run the risk of releasing those spores into the rest of the lawn.

Once this step has been completed, you can then mow your lawn to give the scarifier full access to the surface. It is recommended that you use the lowest setting on your mower to ensure the surface is exposed.

Using the scarifier

Now that your lawn has been properly prepared, you can scarify the lawn using the highest setting initially to ensure that the blades of grass aren’t shocked or damaged. Once you’ve moved over the grass a few times and at different angles you can then move on to a lower setting. 


Once you’ve finished scarifying your lawn it’s worth checking to see if you require an aerator to help aid the drying out process of the soil. If left damp, your moss problem will likely return and all of your hard work will be undone. 

You can also apply some top soil and grass seed to the lawn if you find that it’s looking slightly limp or patchy.
