Last Updated on

So, what is a lawn scarifier? A lawn scarifier is a garden appliance that cuts through the soil and removes moss and thatch, grass cuttings and other garden debris. These gardening tools, which come in manual and electric versions, can also help you to create weed-free, resilient, healthy soil. But there’s more to these gardening tools than just knowing what a lawn scarifier is.

When to Use a Lawn Scarifier

Generally speaking, you should scarify your lawn when it is at its healthiest, which is typically late spring or early autumn.

It’s unlikely that you’ll need to use a grass scarifier more than once a year, although you might need to repeat this process slightly more if your lawn has a lot of moss growth. Otherwise, scarifying shouldn’t be repeated because doing so too frequently will damage your grassroots.

Reasons to Scarifying Your Lawn

  • Enables water to efficiently reach the soil, leading to a healthier garden
  • Allows nutrients to reach the grass
  • Removes dead weeds and moss
  • Encourages healthier grassroots for a greener grass
  • Removes harmful thatch from your lawn
  • Prunes grassroots for healthy growth
  • Potentially prevents any moss problems
  • Provides a refreshing treatment for tired-looking lawns

The Different Types of Scarifiers

There are four types of scarifiers: hand, electric, petrol and bladed. Let’s take a look at the qualities and uses of each tool type.

Hand scarifiers look like a traditional gardening rake, although some can include wheels to make them easier to move across your lawn. These are the most basic types of scarifiers and are effective for collecting and removing debris without having to pick up any mess from your lawn using your hands. They’re also helpful for maintaining your lawn—especially if you only have a small patch of grass.


Powered by electricity, an electric scarifier can cut through soil deeply and turn over the lawn in a more powerful manner than a hand garden tool. This type is excellent for scarifying medium-sized lawns, and there’s not much maintenance involved; simply keep on top of cleaning and cutting the blades. Best of all, they’re quieter than petrol scarifiers, enabling you to use them without disturbing others.


Best for large-size lawns, a petrol garden scarifier requires fuel to operate and generally works for longer periods than an electric scarifier. One factor to consider with this garden equipment is that you’ll need to keep on top of maintaining it to keep it working properly and lasting a long time.


A bladed garden tool comes with blades that can dig deep into soil, moss and debris. However, some garden tools use tins instead of blades that don’t cut deep into the soil but remove dead vegetation from your lawn’s surface, helping to keep your garden looking clean and tidy. They’re best suited for small and medium-sized lawns. A bladed scarifier is an incredibly powerful machine that helps you to obtain a lush garden.

Tips for Choosing the Right Scarifier for Your Lawn

It’s time to start scarifying your lawn, and here are some important factors for the buying process to make sure you get the right equipment.

Lawn Size

One of the biggest factors to keep at the front of your mind is the size of your lawn. You’ll want to limit the amount of time you spend gardening and work as efficiently as possible, which is why you should avoid a hand scarifier for a large yard, for example. However, if there are smaller sections of your garden that you want to focus on at any one time, then a hand scarifier will suffice. Keep in mind that an electric scarifier isn’t appropriate for scarifying larger gardens since you’ll need to keep it connected to a close power source during use. Otherwise, a petrol model makes an excellent choice for larger turf.

Depth Variation

You may want to target different soil depths when gardening, which is why it’s essential to choose a scarifier with different depth settings, although you don’t need anything deeper than 5cm. Consider a model with adjustable depth settings so that you can meet your gardening needs in summer.

Cutting Width

This feature refers to the width that the scarifier covers as you move it across your lawn. A tool with a narrow width will focus on small sections of green at one time, which isn’t efficient for a large lawn. For the best results and minimal work, opt for a scarifier with a width that’s wide enough to cover a large area at one time so you can work quickly.

Ergonomic Design

Gardening can be tough on your body, which is why it’s best to choose a scarifier that’s comfortable and ergonomic to use. Consider a tool with ergonomic handles that cushion your hands during use and don’t strain or cramp your hand. You might also want to consider handles that are height adjustable to manipulate them to your comfort levels.

Is Scarifying Grass Worth It?

Overall, lawn scarifying reduces the growth of moss and thatch on your lawn and provides air and water to your soil, promoting healthier grass.

So, what is a lawn scarifier? Knowing about a lawn scarifier and having the right equipment is just the first step to maintaining a perfectly green garden and being able to enjoy it.
