Is the following statement true or false: The One-Third Rule dictates leaving no more than one-third uncut blade?

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

Answer: (B)

The One-Third Rule means you should not remove more than one-third of the leaf blade in a single mowing, leaving at least two-thirds uncut. If you leave no more than one-third uncut, that means you’re cutting off at least two-thirds of the blade, which is more aggressive than the guideline and can stress or damage the turf. So the statement is false. This rule is a general guideline meant to help turf recover quickly by preserving enough leaf area for photosynthesis and growth after mowing.
