Whether new to the world of scarifiers or looking for an updated model that will help you even further in your mission for that perfect lawn, then this article is for you.

Why Do I Need a Scarifier?
If you are like me, then you might be wondering why you need to purchase a device that will help your grass to get more air – it’s outside in the fresh air constantly – does it really need you investing your well-earned money in a tool to help it get even more air?! Well, actually the answer is yes! The difference that it will make to your lawn really is quite incredible! Now, for the science behind it…
It is important to remember that your lawn is made up of a number of blades of grass (usually around 850 per square foot!). Thatch is an organic matter that builds up between the blades of grass in your garden. There is nothing wrong with this – it is just how lawns grow (basically when blades of grass die they don’t rot, so this build-up continues as more blades grow etc), however, it is bad for the overall growth of your lawn.
You wouldn’t try to grow other plants in your garden so close together, and expect them to grow successfully! Therefore, you really cannot expect the same for your grass, as this thatch, and other matter such as weeds and moss will stop your grass from getting the nutrients, air and sunlight that it needs.
A scarifier is essentially a big rake that pulls out some of the debris that isn’t needed in your lawn. Blades cut into the turf to lift out all of the moss and thatch that is suffocating your precious grass. At the same time, your scarifier will leave small holes in the ground to allow more air and water to get to the soil.

What to Look for in a Scarifier
Although you may only be using your scarifier a handful of times throughout the year, it is important that you buy the right one. Opting for a cheaper, less suitable model may leave your lawn damaged and give you a much harder job than you anticipated!
- The first thing that you need to consider is how you want your scarifier to be powered. For this, you will have three main options: Manual, electric and petrol.
- Manual scarifiers will usually be cheaper, and are considerably cheaper to run as you only need to fuel yourself! However, they are going to be a lot more difficult to use than electric or petrol models as you will have to have the strength to push the machine and the blades through the grass.
- Electric models will be easier to use than manual models, but you have the disadvantage of being limited to how far away from a mains power source you can travel (which is going to be an issue with a bigger garden).
- Petrol models will save both the problems with the ease of use of the manual scarifiers and the lack of flexibility as to how far away from your house you can work, which is an issue with the electric models. However, petrol scarifiers are considerably more expensive than their electric and manual counterparts, and will also be heavier and more costly to use!
- The more teeth, claws or blades the better! On average, scarifiers will have between 14-20 blades. The more blades, the more organic matter they will be able to rake up in one go! Also consider the quality of the blade material (stainless steel, tempered steel etc) as this will affect how long you can expect them to last and stay sharp.
- Some scarifiers will have blades that can be individually replaced. This may sound like a bit of a faff but will save you considerable time and money, and make sure your scarifier has a long life!
- Cutting width and depth – many scarifiers will only cut the surface of your lawn (cutting at most a few millimetres in depth). Many mid to high-end models offer deeper penetration tools that will scarify between 2.5-5cm deep – this means that you will be able to use the tool as an aerator as well, for maximum lawn care. Consider models that offer adjustable depth so that you can find what is right for your garden.
- Cutting width – this is the width of the rotating strip that holds the blades. The wider the strip, the more of your lawn that will be covered at one time. This means you will have fewer lengths of the lawn to do!
- Last but definitely not least is the usability – This is particularly important if you have a larger lawn as you will be using your scarifier for even longer! Consider the position of the handles and if they have a comfort grip, the collection bag capacity as this will affect how often you need to stop to empty it and finally the weight of the scarifier as this will affect how easy the machine is to propel up your garden.
TOP TIP: Look out for scarifiers with a longer warranty – if you are only going to be using your scarifier a couple of times a year, you want one that is going to last a number of years so you can get your money’s worth! Most scarifiers have around a three-year warranty!
What is the difference between an Aerator, Raker and a Scarifier?
These three tools are often seen as being the same thing but they are actually massively different! An aerator is used to put holes in your soil so that fertilizer and water can penetrate the soil to help the growth of your lawn. A lawn raker is closer in use to a scarifier but doesn’t actually have blades that can cut into the thatch and moss to remove it. This means that the cylinder will simply comb through the lawn removing any loose organic material. Whereas a scarifier is able to destroy vegetable matter with its blades which rake the ground, removing plant debris and weeds. Some scarifiers do now also come with an aerator feature, but you would be hard-pressed to find an aerator that comes with a scarifier feature!
How and When to Scarify
Scarifying is a really simple process – once you know-how. Follow our simple instructions to make your first scarifying experience a good one!
The most important thing to remember about when to scarify is to make sure that you never complete the work in winter, as this will really damage your lawn. If you are only lightly scarifying and don’t have a lot of organic matter to remove, then you can complete the job in late spring to around April, and then again in late summer to early autumn. However, if you have never scarified your lawn, and it appears to have a lot of thatch and moss then we would recommend leaving your scarifying until middle to late autumn (just be sure to not scarify if your grass is particularly wet). It is important not to scarify your lawn too often – we would recommend twice a year!
- Make sure your grass is not too long before you start scarifying – this may mean you mowing your lawn before starting!
- Remove any large weeds or stones from the lawn first.
- Make sure to start at the highest setting and then work your way lower until you are happy with the amount of moss that has been lifted. Starting at the lowest setting could leave you with a number of bald patches on your lawn if you are not careful, so although it will take longer to go over your lawn a few times with a lower setting each time, this is the best way to ensure your grass does not become too damaged.
- Simply push your machine forwards along your lawn (as you would a lawnmower). As you do this the blades will rotate and tear through the organic matter that you are hoping to remove.
- Some models will come with collection bags whereas others will leave the debris behind as you are moving forward (this is actually sometimes better with the amount that is often lifted out of the lawn!).
TOP TIP: Make sure to not scarify your lawn if it is too damp, particularly first thing in the morning. As well as this is it important your lawn is growing well before you scarify, otherwise, you could damage it irreparably.
After scarifying your lawn, we would recommend applying a moss killer (to remove any determined, leftover moss) and applying a lawn feed (to help your lawn recover and grow quickly).
Any bare patches that have been created from scarifying should be reseeded during the start of autumn to allow the grass to grow strong and provide you with a healthy, green lawn the following year.

Frequently Asked Questions
Most lawns will benefit from a scarifier at some point! In fact, it would be unlikely that you would find a lawn that wouldn’t. If you lawn feels springy and spongy to the touch or has yellow patches at the base when you move the grass apart with your fingers – then you need a scarifier for your lawn. However, it is always beneficial to use a scarifier on your lawn before it gets to this point if you want it to be growing as well as possible!
Don’t panic! This is totally normal after you have first used a scarifier on your lawn – especially if it has become taken over with thatch and other organic debris! A scarifier can leave your lawn looking a bit of a mess, this is because it is has removed a lot of the bad stuff that you don’t want to take over your lawn. But we promise that it will be worth it, once your lawn starts to grow properly and uninhibited by the thatch then you will see fantastic results!
If you have a particularly large lawn that is in need of scarifying then you can purchase ride-on accessory scarifiers for your ride-on mower! Your ride on-mower will have to support these attachments, so it is important to bear this in mind, but if it does then you will simply be able to connect it to the back of the mower and tow it behind you (be mindful that you will probably have to rake up the debris afterwards though as these models do not come with collection bags).
