Does proper mowing frequency involve leaving at least two-thirds of the leaves uncut?

• A. True
• B. False
• C. It depends on grass species
• D. It depends on season

Answer: (B)

The key idea is that mowing should remove only a small portion of the leaf blade in each mowing, not that you fix a frequency based on leaving most of the leaf uncut. In turf care, the common guideline is to cut off about one-third of the leaf blade per mowing to minimize stress and keep the turf healthy. That means you generally leave roughly two-thirds of the blade after each cut, but this rule describes how much to cut in a pass, not how often you mow. Mowing frequency is driven by how fast the grass is growing and the target height, so while you might mow more often when growth is rapid, you still aim to remove no more than about one-third each time. Because the statement misframes the principle as a frequency rule, it’s not an accurate description of proper mowing practice.
