What Is Scarification?
Scarification is the process of removing thatch from the lawn. Although a certain amount of thatch is desirable in all lawns, an excessive level of thatch will cause severe problems.
Thatch is a layer of dead grass cuttings, dried leaves and other organic debris that falls on the lawn. In most cases the bacteria in the soil will break this thatch down. In a number of lawns the bacteria cannot cope with the levels of debris and we get thatch building up. This acts as a barrier between the soil surface and the atmosphere.
Thatch can be removed by scarification which uses machines with vertical blades slicing through the thatch, scraping the soil surface and removing the thatch.
Scarification can reinvigorate your lawn, giving it a fresh start in Autumn or Spring.
