At what height should I mow my lawn?

Warm season grasses like Bermuda and zoysia can be personal preference. Golf courses mow as low as 5/8” on greens and tee boxes while areas outside of fairways may be as tall as 3-4”. The lower your height, the more frequently you need to mow. Never take off more than 1/3 the blade length on each mowing. Cool season grasses like Fescue in our area need to stay high, around 3-4” for best results.
