Proper Mowing Height #914074

Asked August 14, 2025, 7:12 PM EDT

I prefer to cut my mostly Bluegrass lawn at 4". My neighbors continually give me static about this and suggest 3-31/2" cutting height. What is the recommended height for plant health (not aesthetics)? I was always taught 4-41/2". Lawn seems healthy to me- and not "overgrown" see pics- no watering at all in 2025! Am I wrong?
