Dethatching is done much more now than in the past.

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

Answer: (A)

Dethatching removes the thatch layer—the buildup of dead and living plant material between the soil and the green growth. This layer can block water, air, and nutrients from reaching the soil, so it’s only done when thatch becomes thick enough to cause problems, typically around a half-inch or more. With modern lawn care, emphasis is on preventive practices like proper mowing height, balanced fertilization, and especially aeration, which help keep thatch from accumulating. As a result, dethatching is used selectively and not done more now than in the past; in many cases it isn’t needed at all unless the thatch threshold is reached. When it is necessary, dethatching restores soil contact and turf vigor.
