The blades may also dislodge a small amount of thatch but should not penetrate into the soil or turf root zone. Verticutting or light scarifying uses a machine fitted with blades that reach vertically into the turf canopy and are set to a depth where they can achieve their objective of cutting through laterally growing and creeping grasses. SISIS has become renowned for specialising in the production of equipment for scarification. During scarification, lateral grass growth can also be controlled. There is a wide range of pedestrian-operated and tractor-mounted equipment available to combat this. Thatch build-up is particularly noticeable where there is a prevalence of annual meadow grass, in fine turf and where the grass is mown regularly and cut low.

It can be of benefit where a layer of fibrous material has built up and is beginning to cause problems with water infiltration or during renovation work prior to top-dressing. Whether you need to do any or all of them will depend on the species of grass in your turf and the condition of the sward.Дeep scarification is a deeper action, usually done twice yearly which penetrates the surface вЂ“ deep into the thatch layer to remove fibres, debris, thatch and moss.

These turf maintenance operations vary in their objective, the depth to which they are performed and the machinery used to carry them out. What is the difference between scarifying and verticutting? And do I need to do them both? Andy Walker, Field Support Manager for SISIS says that the most frequent question he is asked is how deep does the machine go? In his opinion, that is not the correct way to control thatch and here are some commonly asked questions heвЂ™s asked to answer. ItвЂ™s fair to say that when you talk about thatch, many people say that you need to go deeper and deeper into the soil to remove it.
