What is a lawn scarifier?

A garden can’t look at its best if the grass isn’t in tip-top condition. While there are many things that can help to keep it looking great, including regular mowing, one underrated tool is a scarifier. You may have heard of a scarifier before, but do you know what they’re used for? Essentially, they keep your grass healthy and ultimately looking as fantastic as possible. 

They’re used to remove thatch from lawns. So what’s thatch? It’s a build-up of organic matter that will happen naturally in any living area. They’re a combination of various organic materials, including old leaves, stems, weeds, and dead grass. While these things can seem harmless enough, they do impede the healthy growth of grass. That’s because they can block nutrients, light, water, and oxygen from reaching the grass. Unable to penetrate deeper down, a lot of water can end up just sitting on top of the grass, which makes it an ideal spot for moss to grow. While that’d be good if you were hoping to have a mossy garden, it’s not going to help you if your goal is to have a beautiful lawn with lush green grass. Lawn scarifiers are used to break up this thatch. 

How to use a scarifier on a lawn 

So now let’s think about how we can use a scarifier to keep your grass healthy. 

The first couple of steps won’t involve using the tool. You should begin by taking a look at your lawn and get rid of any obvious debris. Just before you use your new device, get out your lawnmower, and go over the grass a few times. You want your grass to be as short as possible in order for your scarifying process to be as effective as possible. You can do this over a period of weeks. If your grass is long, then get it down to a respectable level. Then, the day before you intend to scarify your lawn, cut the grass as close as possible. 

After you’ve done this, you’ll be ready to use your scarifier. When you begin, you can whack the device to its highest setting and then go over the grass, using the same technique as you would use when using your lawnmower. That means, essentially, that you should go over every inch of grass. In some cases, this will be enough. But on lawns where there’s a lot of thatch, you’ll want to go over for a second pass. This time, though, you’ll want to use a lower setting. It’s best to go at a different angle the same time you go over the lawn so that you’re covering as large an area as possible. 

This might be enough for your lawn, but if you’re planning to throw down some grass seed, then you’ll want to go over the third time. This time, you should cut into the soil, not much, just around a centimetre or so. This will give a great bed upon which to plant your grass seed. It’s best to follow the instructions that come with your grass seed, but you can also consider covering up your seeds so that they’re able to grow as healthily as possible. Anything that protects them from the elements will do the job; many people use fine compost and sand. 

What is the difference between lawn rake and scarifier?

You have more than one option when it comes to removing thatch from your grass. In this blog, we’ve talked about a scarifier device, but you may have also heard that you can use a lawn rake. So what’s the difference? 

Perhaps the biggest difference is that scarifiers are a lot more intense; they go deeper and have longer-lasting results. Raking is used for removing moss and other minimal amounts of thatch. You can use them every couple of months since they have less of a dramatic effect on your yard. Scarifiers, on the other hand, are for a deeper treatment. You can use a scarifier once a year and see excellent results. 

Lawn rakes come in both electric and manual form. While you can rake manually, there’s no avoiding the fact that this is hard work. For the best results, use a scarifier. 

When to use a scarifier

As we mentioned just above, you can usually just your scarifier once a year. But at what time of the year should you use it? The best time is just before the main growth cycle of grass. This is because you’re essentially making your yard worse in order for it to be better. If you use a lawn scarifier during the autumn, then you’ll have the ideal setting for new, healthy grass to grow. If you did it in Spring, then you’d be preparing the ground for weeds to take over, since that’s when they come to the fore. Plus, one major advantage of doing it in Autumn rather than Spring is that you’re unlikely to use your garden all that much during the colder months, but will use it in Spring and Summer.
