Category Archives: Thick Lawns and Thatch Problems

Thatch is the term given to the layer of organic matter on the soil surface of the lawn between the roots and the grass leaves.

A thick lawn is often caused by over feeding. Too much leaf growth causes it to build up uncontrollably. It can also come from lack of maintenance over a very long period of time or an infrequent mowing regime.

A thatch layer or organic matter will smother a lawn. Water and nutrients will not be able to get to the roots. New growth cannot come through and the thatchy layer is a great incubator for damaging fungal diseases such as red thread and fusarium.
