  • I Ground texture The so-called "lawn thatch" grows best on loamy soil, shaded lawns or surfaces, which tend to stagnate. These floors should be more frequently raked and scarified.
  • I Correct timing for scarifying The best time to scarify is in spring (April) and autumn (September). After the scarification, the lawn should have time to regenerate. It is advised mow the lawn before scarifying.

Scarifying / Lawn Raking

What is the difference between Raking or scarifying the lawn? Almost every garden owner dreams of an attractive, lush green lawn. But why do some gardens look like a dried-out desert and the lawns of the neighbouring garden appear every year in the most beautiful green? Most of the time, it is because the neighbor regularly rakes and scarifies their lawn. Two processes that are indispensable for a healthy garden lawn. Lawn raking is necessary so that the lawn can absorb enough nutrients and get enough air to breathe. Scarifying is simply explained, more intense raking, in addition the ground is lightly penetrated. Gardeners tend to scarify their lawn mostly in the spring to refresh it after the cold season and again in autumn. This is process is required so that the lawn gets the necessary nutrients again, in order to be able to overcome the next winter well.

What exactly does scarification mean?
scarifier has a roller with stepped steel blades. These penetrate into the surface of the lawn and remove thatch, moss and plant remnants. This can be compared with a fixed, narrow-tipped rake, which slides lightly into the ground and also removes some of the healthier lawn. This method can also be used for small areas. A motorised scarifier is recommended for large lawns. No matter what type of device is used, it is important to remove the parts of the plant which have died out during the winter as they prevent new grass to grow. Please note that only dry, freshly mown lawns should be scarified.

When and how often is the lawn to be raked?
In order to achieve a good result from scarifying, the grass should be cut to a length of 3-4 cm. This makes it easier for the scarifier to get through the grass. The lawn should not be treated too early - only when the risk of ground frost can be excluded. It is also important that the soil is dry. This means that depending on the weather, March or April are the best times of the year for scarifying. If you wish to carry out a second treatment, September is probably the most suitable, as long as sufficient soil heat is present. Tip: The collected debris from scarifying should not be added to the compost bin.

Don't forget the lawn raker.
In addition to the scarifying, the lawn should be raked regularly. Our machines are already equipped with a raking cartridge. In contrast to the scarification, lawn raking can be completed throughout the year, so that the green leaves stay healthier for longer. Steel spring tines go through the lawn removing and dead grass and other organic debris allowing light, oxygen and water easier access to the roots of the grass.

After lawn raking and scarifying.
In both cases, the grass should then be heavily irrigated and fertilised. A benefit for the soil and plant in addition to the increased oxygen levels is the easier access for water to reach the roots making it an ideal time to fertilise your lawn. New lawn seeds should also be used to create a thicker lawn. Conclusion: Lawn raking and scarification should not be underestimated by any gardener. Scarify once or twice a year, and apply a fertilisation treatment so that it appears and healthy and green in spring. Anyone who adheres to it does not need to be envious of neighbour’s garden.

The right scarifier for the job.
When purchasing a scarifier, you should pay particular attention to the working width and the functionality - scarifying and raking. Sometimes it is necessary to use a hand-held tool, for example a rake. This makes work difficult, labor intensive and is especially difficult on a larger lawn. The electric and petrol scarifiers makes it much easier to work and reduce the effort required. High-quality scarifiers also collect the debris and the dead plant remnants in a collector bag, so the clearing up afterwards is no longer necessary. While petrol-powered engines usually have more powerful engines and are thus optimally aligned for larger lawns, electrical scarifiers are particularly appealing because of their lower weight. The main drawback here is the power cable, which is required to lay along during the entire working area.
