Improve your Lawn with a Lawn Scarifier


If you’ve ever wondered how you can improve the look of your lawn, and how it grows then this article should help.

Improve your Lawn with a Lawn Scarifier

Lawn Scarifiers usually look a bit like a lawnmower and is sometimes referred to as a de-thatcher. This garden tool is designed to cut through the top layer of soil, removing dead moss grass cuttings and other debris.

As the Scarifier cuts into the soil, the tines (prongs) help to aerate the soil, making it healthier by removing the majority of the weeds.

Benefits of a Lawn Scarifier

If you don’t regularly de-thatch your lawn, dead grass cuttings and moss will choke the surface, preventing rain water from penetrating the ground. When rain falls on a choked lawn, it will sit on top making your lawn boggy.

Excess moisture can also encourage even more moss growth, making the problem even worse.

Mossy Lawn - Needs a Scaifier

How to Use a Lawn Scarifier

Before deploying your scarifier you should check over your lawn and remove any live moss or debris. Use a good moss killer, spread the moss killer on your lawn following the instructions. This step will prevent you from spreading airborne spores of the live moss all over the garden with your scarifier.

Once you are sure that the moss is dead mow your lawn on a dry day, with the mower on a low setting.   Doing this before you use your lawn scarifier means that you can collect the cut grass at the end of the task.

Put the scarifier on a high setting and work over the surface of the lawn a couple of times. Then repeat the process at angles but reduce the severity of the settings on each pass.

Re seeding a lawn

If your lawn is looking thin and worn, it’s a good idea to add some extra seed. A great idea if your lawn is looking tired. Cover the seed with a mixture of some compost and/or sharp sand this will protect the seed whilst they germinate. This technique is known as ‘over seeding’.

When to Scarify

The best time to scarify your lawn tends to depend on your location and the weather. The best time to scarify is when the turf growth is at its most prolific. The growing season is normally in the autumn or late spring.

Scarifying your lawn once a year is normally enough, though you may need to do do it more often if, your lawn is in poor condition. Scarifying your lawn does cause some damage to the grass and its roots. So scarify sparingly.
