Mowing height and frequency are important in lawn health because which of the following is true?

• A. Clippings break down rapidly when turf is mowed regularly
• B. Removing too much of the blade at one mowing may result in physiological shock to the plant
• C. Fewer fungal diseases occur when turf is maintained at a proper height
• D. All of the above

Answer: (D)

The main concept here is that mowing height and frequency directly affect turf vigor by influencing photosynthesis, recovery, and disease conditions. When you mow regularly with small, frequent clippings, the grass shares nutrients back into the soil as the clippings decompose quickly, helping the lawn stay healthier. If you cut off too much leaf in one mowing, the plant loses a lot of its photosynthetic area at once, which can stress it and slow recovery. Keeping the turf at an appropriate height also improves air circulation and helps leaves dry more quickly, reducing the conditions that favor fungal diseases. Since all these points are true, the option that encompasses all of them is the best choice.
