Lawn Thatch is a layer of decaying organic matter on the surface of your soil. It consists of grass cuttings, stems, crowns and other parts of the grass plant that are no longer viable.
All lawns will have a thatch layer and as long as it is kept under control, about half an inch or less, it can have beneficial effects such as providing a cushion to the lawn’s surface and also as a breeding ground for beneficial macro and micro organisms.
It’s when the lawn thatch layer gets out of control that problems start. This organic mat covering the soil’s surface starts to restrict the flow of water and nutrients down into the root zone. It also becomes a fertile breeding ground for potentially dangerous grass pathogens and insects that attack the grass plant. As the thatch layer also holds onto water it encourages the development of moss.
Lawn Thatch can be removed by a process called Scarification where a petrol powered scarifier cuts into the thatch mat and removes it to the lawn’s surface where it can be safely removed.
