What Is Thatch?

Thatch forms from undecomposed plant debris — such as old grass material and fibrous root build-up — that accumulates between the topsoil and the visible grass. While a minimal amount is expected, a thick layer can restrict drainage, limit access to nutrients, and lead to fungal conditions. The turf may look patchy, feel bouncy, and struggle even with routine maintenance.

When and How to Reduce Thatch

Thatch reduction manages the thatch layer before it worsens. This is often done using scarifying machines that cut into the turf and extract dead material. By allowing air and water to reach the roots, turf remains healthier and more durable.
