Dethatching is done much more now than in the past.

• A. False
• B. True
• C. Sometimes
• D. Never

Answer: (A)

Dethatching is used to remove the layer of dead and living organic material that can accumulate between the soil and the green shoot, called thatch. The need for dethatching depends on how thick that thatch has become, which is influenced by grass species, climate, and how the lawn is managed. In many modern lawns, thatch buildup is kept under control by practices like proper mowing height, balanced fertilization, and choosing grasses that don’t accumulate excessive thatch, so dethatching isn’t a routine or increasingly frequent task. It’s typically performed only when the thatch layer becomes thick enough to impede water, air, and nutrient movement—often around a half inch or more for cool-season grasses, though thresholds can vary by grass type and region. Signs that dethatching might be necessary include a spongy feel underfoot, poor water infiltration, moss growth, or shallow rooting. After dethatching, aeration or overseeding may be recommended to help the lawn recover. So the statement that dethatching is done much more now than in the past isn’t accurate; it’s usually done as a remedial measure when needed, not as a frequent or ever-increasing practice.
