Excessive thatch is very common in lawns that have not had regular maintenance. Thatch is a loose, intermingled organic layer of dead shoots, stems, and roots that develops between the zone of green vegetation and the soil surface.
Thatch build up begins when turf produces organic debris faster than it can be broken down.
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.
Moss is also is very common in lawns that have not had regular maintenance. It is important to reduce moss levels as well as thatch, as dead moss turns into thatch. Regular moss control applications also help reduce thatch levels.
