Buying Guide

What are They?

It looks almost identical to a lawn mower, coming with four wheels, a handle, an engine, and rollers, although it doesn’t have a rotary blade like a mower.

Why Use Them?

Mowing the lawn is one of the most common types of garden maintenance, yet almost nobody considers using them, which is arguably just as important. While not needed as frequently as mowing, this is an important form of maintenance that will significantly improve lawn quality.

Over the seasons all types of natural debris accumulate on a lawn. This includes moss, dead leaves, roots, clippings, weeds, and other types of debris. When left untreated, which often happens during winter, this debris builds up across the surface of a lawn, hampering growth by limiting the amount of water, air, and nutrition that penetrates the soil.

As a result, lawns with too much thatching become over-acidified and lack a healthy growth. By using them you can remove the lawn thatch to aerate the soil, helping restore it to its natural appearance.

Different Types

Just like a lawn mower there are several types of lawn scarifiers available. Differences are typically the power source and the type of cutting device used to aerate.

  • Manual –  A manual lawn scarifier features no power source, being operated entirely by pushing the tool across the lawn to aerate the soil. These are suitable for smaller lawns measuring up to 100m2.
  • Electric  – Electric models are more suited for average size lawns between 100-500m2. They are plugged into a power source like an electric lawn mower to power the cutting device, which is usually a blade, teeth, or claws.
  • Petrol – Petrol scarifiers are the most powerful type available and suitable for large lawns upwards of 500m2. While much stronger they also require more maintenance, namely engine components like spark plugs and filter, while oil changes are also common.

Aerator or Blades?

 Categorised by the cutting mechanism used to aerate, being classified as either bladed or an aerator. Both work to aerate the lawn to make it healthier and improve growth, although each one achieves this differently.

For example, aerators are fitted with either claws or teeth. These attach to the lawn thatch to help clear the surface area, which allows air and water to better penetrate the beneath the soil. It mostly removes moss build ups from the surface and isn’t recommended for lawns bigger than 300m2.

Bladed scarifiers feature a series of small blades that actively cut up natural debris in the lawn thatch. Rather than simply removing them, they chop up moss, leaves, and weeds as they pass over, gathering the loose clippings into a collecting bag like a lawn more does.

By destroying the plant matter and raking the soil, the blades are generally more efficient than aerators, making them better suited for lager lawns. They are also much more power, so are usually found in electric and petrol lawn versions.


What does a scarifier do to your lawn?

Aerates a lawn by removing build-ups of dead plant matter, such as clippings, leaves, moss, weeds, and other natural debris that accumulate on the lawn. By removing this surface material and puncturing the soil below, the tool aerates the soil to improve airflow and drainage, both of which encourage healthy and vibrant grass growth

When should I scarify my lawn?

You only really need to scarify your lawn once or twice a year, although this depends on the condition of your lawn, with most doing it growing season.

For instance, it’s usually a good idea to scarify the lawn at the beginning of spring and the growing season. This is because lots of debris accumulates over the winter months, especially when the lawn isn’t getting mowed.

It’s often a good idea to scarify the lawn before the winter too, around late autumn time, as the build up leaves is a common cause of lawn thatch, as does the growth from throughout the growing season.

Can you scarify wet grass?

It is not a good idea to scarify the lawn when it is wet. While you want the lawn to have some moisture present before scarifying, doing so on wet grass is not recommended as it may cause the lawn scarifier to pull up healthy grass growth rather than dead matter lying on top of the surface.

How often should I scarify the lawn?

Scarifying your lawn once or twice a year should be more than enough. Doing this during the growing season is recommended, as you want to remove as much lawn thatch as possible before peak growth to ensure healthy lawn growth.

What is lawn thatch?

Lawn thatch is the name given to the debris that accumulates on the surface of a lawn over the weeks and months. Dead plant matter such as grass clippings, weeds, and moss build-up across the soil surface of the lawn to create a thatching that blocks water, air and nutrients penetrating the soil.

Do I need to dethatch my lawn?

Yes, detaching or scarifying your lawn is advised if you want healthy and vibrant grass. Lawn thatch deters growth as it blocks the soil, making it difficult for water, air, and nutrients to naturally pass into to soil and encourage healthy grass growth. So, if you want the best lawn possible you need to dethatch a few times a year. 

How do you use them?

They work almost identically to a lawn mower. Set it to the highest setting and then start passing over the entire lawn surface like you would when mowing. Make several passes over the lawn to ensure all lawn thatch is properly removed, reducing the power settings on each subsequent pass. 

Another model to consider is the  Bosch ALR Electric Lawn Raker.
