What Is Thatch?

Thatch is a layer of organic matter — typically dead roots, shoots, and stems — that accumulates between the topsoil and the visible grass. While a minimal amount is expected, an excessive build-up can impede water absorption, limit access to nutrients, and lead to fungal conditions. The turf may appear uneven, feel spongy, and struggle even with routine maintenance.

When and How to Reduce Thatch

When Thatch Removal Is Unavoidable

If the thatch becomes too deep, full removal may be the necessary next step. This process uses heavier equipment to cut beneath the thatch and clear out organic congestion entirely.

Symptoms such website as standing water, slow recovery, and a springy texture—all of which suggest reduction won’t suffice. click here In these cases, thatch removal restores proper turf-to-soil connection.
