Scarification is a very important part of keeping your lawn in a good condition. It is a mechanical rake-like process which removes unwanted and potentially harmful thatch from the surface of your lawn. Thatch is a build up layer of surface and sub-surface dead grass, grass clippings and moss that can accumulate over many years.
A build-up of thatch and moss can becoming damaging to a lawn by preventing water, air and nutrients from reaching the soil and root zone. As a result lawns will suffer by becoming thin, patchy and let stress tolerant. Removing the layer of organic matter from your lawn encourages a healthier and more resilient grass growth as well as a denser sward.
The optimum time of year to carry out scarification or general lawn renovation/repair work is during the spring and autumn months*. This is because the soil needs to be warm and damp to assist natural recovery and seed germination.
As a general rule we advise scarification at least every other year.
*Scarification can also be carried out between May-August providing there is the facility to water the lawn if required.
At Will’s Norfolk Lawns we use professional scarifiers with adjustable rotating reel blades. They cut vertically through the living material to remove surface thatch, which is not normally affected by horizontal mowing. We usually carry out lawn scarifications as part of our Lawn SAS or Lawn Improver packages. We collect the debris following scarifying using backpack a blower, rake or rotary mower.
