Over the course of a year, dead roots, grass clippings, leaves and other organic matter all increase the layer of thatch which forms at the base of the grass stems.

As this mat increases in density, it prevents important nutrients, as well as water and air, from reaching the root zone. It also provides a perfect environment for moss to flourish.

To treat moss, Greenfeet addresses the cause of the moss, and to this end will remove the surface thatch on which the moss is growing.

Scarification is the mechanical process of removing surface thatch from a lawn. It should not be confused with lawn raking using either a spring tine rake or an electric machine with hook line tines.

Rakes and domestic machines are relatively good at removing dead moss, but they have little or no effect on surface thatch.

Scarification is undertaken in conjunction with Over seeding and the application of high P fertilizer. The area will need to be watered intensively after the treatment to help the new seed strike. The appearance of the lawn will get worse before it gets better. This will generally take approx 6 weeks.
