Question

The process of removing a layer of dead and decaying organic debris and stems from the top layer of grass is known as:

• A. Scraping
• B. Dethatching
• C. Spiking
• D. Raking

Hint:

Regular dethatching helps maintain healthy turfgrass by improving air, water, and nutrient penetration.

Answer 1

The Correct Option is B

Dethatching is the process of removing the thatch layer, which consists of dead and decaying organic material, such as stems, roots, and leaves, that accumulate on the soil surface beneath the grass. This layer can prevent water, nutrients, and air from reaching the grass roots effectively.
Scraping (A) generally refers to physically scraping soil or debris but is not specific to thatch removal.
Spiking (C) involves making small holes in the lawn to improve aeration.
Raking (D) is used to remove loose debris but may not effectively remove compacted thatch. Therefore, dethatching is the appropriate process for removing the dead organic debris layer from grass.
