Summary

Thatch is the layer of dead and living stems, leaves, and roots that builds up at the soil surface when turf grows faster than it can decompose. A small amount helps cushion and protect turf, but too much can block water movement, limit rooting, and shelter insects and diseases. This guide explains how to measure thatch depth, when to dethatch, and which tools work best. It also outlines prevention steps like proper fertilizing, drainage, cultivation, and topdressing.
