Due to the growth of moss and weeds in combination with you mowing the grass, your lawn can clog up. Keep the lawn airy and healthy by scarifying at least once a year. In doing so, you remove the layer of dead mosses and grasses.

  • A scarifying rake or scarifying machine;
  • A leaf rake;
  • Lawn fertilizer or grass seed to restore the lawn.

How does scarifying work?

Scarifying is a rather heavy job, but with the right tools - a scarifying rake or scarifier - it only takes a few minutes. You can remove the layer without bending. The sharp blades go up to 1 centimeter deep into the ground and cut the roots of the mosses. This will kill the mosses and afterwards you can easily take them out of the grass with a normal rake. Water can enter the soil again, and the same goes for light and air.

Why is scarifying important?

Unfortunately, plante waste formation can not be prevented. Eventually, grasses and mosses will form a layer in every lawn and stifle it slowly. This can be recognized by: unevenness, no absorption of water, dying grass and large moss spots in the lawn. The beauty of your lawn will fade away with moss taking over and the grass eventually disappears completely. Of course you do not want this to happen. Scarifying once a year is the solution for this!

You can also slow down the process. Mosses like to grow in a shady environment. By giving the sun more space in your garden, moss growth will be inhibited. More light can be achieved, for example, by pruning trees or shrubs. Is this not possible or do you not prefer this? In that case, keep an eye on the acidity of the soil and take action when necessary.

A scarifying rake or scarifying machine?

We advise you to use an electric scarifier in a large lawn. Since it is a heavy job and the machine is a lot faster and less labor-intensive. With a small lawn, a scarifying rake is in principle sufficient and of course cheaper.

The great advantage of a scarifying machine is that you can adjust the depth of the blades and evenly scarify everywhere. Choose a small electric scarifier or a petrol driven machine.

When and how often is scarifying needed?

You do not have to scarify your lawn often, at least 1 and at most 2 times a year. The frequency depends on the lawn. If you suffer a lot from moss growth, scarifying a second time may be necessary. Normally you only scarify in April or May. Do not scarify too early in the spring. The grass hardly grows, so scarifying will have a negative result. First feed the grass so that it will grow faster and become stronger. You can scarify after the first 3 to 6 mowing sessions.

Does the soil consist of clay or peat and/or do you suffer from moss growth? Then repeat the scarifying in September or October. Mosses grow much faster on clay or peat soil because the soil is more acidic.

In winter restore the lawn by removing the mosses (again) in October and possibly sowing new grass, and you are assured of a beautiful lawn in the spring.

How do I scarify my lawn?

Follow the following steps when scarifying:

  1. Lightly moisten the grass. As a result, the grass will recover quickly afterwards;
  2. Mow the grass and remove the grasses, so the mosses will be easier to reach later;
  3. Adjust the blades of the scarifier well (1 centimeter for a thick layer and 0.5 for a thin layer);
  4. Scarify the lawn once in the longitudinal direction and once in the width;
  5. Rake the dead mosses from the grass;
  6. Sow any grass on the bare spots or lay new sods;
  7. Fertilize the lawn to promote the growth of new grass;
  8. See where bare spots have arisen and whether it is possible to get more sun in those places. Prune away any branches that provide shade;
  9. Do a soil test to determine the acidity of the lawn and if necessary add lime or iron sulphate to the lawn.
