Excessive thatch is very common in lawns that have not had regular maintenance. Thatch is the build-up of organic matter and debris, between the lower leaf levels of the lawn.
The thatch forms like a thick matting layer, making the lawn feel spongy when it is walked on. When it is excessive, thatch stops the lawn from getting all of the nutrients that it needs to remain healthy. Fine grass lawns that consist of fescues and bents tend to build up more thatch than ryegrasses do, because of their growing nature.
Regular scarification should be completed in order to reduce thatch levels. This will help to improve access to the root-zone for nutrients.
