Which statement is true about verticutting?

• A. It is a chemical treatment
• B. It is a mechanical thatch removal
• C. It adds soil
• D. It uses irrigation for thatch removal

Answer: (B)

Verticutting is a mechanical method used to remove thatch from turfgrass. A verticut machine uses vertical blades that cut into the thatch layer, slicing and lifting out the accumulated organic material. This isn’t a chemical treatment, and it doesn’t add soil; it physically removes thatch to improve air, water, and nutrient movement to the roots and crowns, helping the turf recover and grow more vigorously.

Because it is a mechanical process, it’s typically done when the grass is actively growing so it can recover quickly. After verticutting, turf managers often overseed and/or topdress to repair the open slots and promote even recovery. Irrigation may be used as part of post-treatment recovery, but not as the method of thatch removal itself.
