Lawn scarifying: It looks destructive, but it works!
Lawn scarifying removes moss and thatch, so your grass can breathe, absorb nutrients, and grow stronger. Learn why and when to scarify for a healthier, greener lawn.
Does your lawn look patchy, dull, or overrun with moss?
The problem might not be your grass at all, but the thick layer of thatch (dead grass, moss, and organic matter) sitting on top of the soil. This layer blocks air, water, and nutrients from reaching the roots of your grass, causing patchy growth.
That's where lawn scarifying comes in. By cutting into this thick layer and removing it, you open up the soil and give your grass the breathing room it needs.
Why does scarifying your lawn help with patchy grass?
Scarifying might sound a little harsh, because you're effectively tearing up your lawn. That's the bit that usually puts most people off, because you're going to make your lawn look, well, pretty bad.
And yes, your lawn will look quite bad for a few weeks, but it's for a good cause. By removing this thick layer of thatch, you're letting the soil breathe a little. Moisture, sunlight, and nutrients from the falling rain and wind will reach the soil again.
After a week or 2, you'll start to see some grass start to peak through the soil. Give it another few weeks, and those empty patches will start to fill themselves in with fresh new grass.
Another benefit of lawn scarifying, that you might not instantly think about, is that it also helps to prevent lawn diseases and fungi. The thatch traps moisture, prevents airflow near the soil, and that's a great place for fungi to grow. Lawn scarifying makes the air less of a breeding ground for these unwanted lawn guests.
How do you scarify your lawn?
Lawn scarifying is actually quite easy and there are a plenty of tools to do this. You can find electric tools that make the process quite simple and fast. If you're not afraid for a bit of sweat, and you enjoy working in your garden, you can also use manual tools, like a scarifying rake. This is my personal favorite way of doing this.
Much like a normal rake, you make sure the hooks are in the thatch layer, then you pull the rake towards you. If you rip out big chucks of your lawn, you're not doing it incorrectly, you just have a lot of thatch (take a look at the previous photo).
You'll quickly notice how much thatch you have on your lawn, trust me, you'll be surprised.
When should you scarify your lawn?
You can't scarify your lawn all year round, because the grass needs to be able to grow and recover from your treatment. The best times to scarify are spring (April–May) and early autumn (September–October). Your lawn is actively growing during these months, so it can recover quickly.
Avoid scarifying in extreme heat or during winter, when grass growth is slow. With just one or two scarifying sessions a year, you'll notice a stronger, greener, and healthier lawn that can handle whatever the seasons throw at it.
In the spring, you can combine your efforts by scarifying your lawn, followed by seeding, fertilizing, and top dressing your lawn. First, you open up your lawn for new growth, and next you feed it.
Yes, it can be quite a bit of work, but the effort is worth your troubles! I know my cats love the healthy grass to sleep in during the day!
