I was cutting every 5-7 days but by the advice given to me at this site by Frank I now am cutting it every three days to try to control my weed situation. Yes it's true. No matter what type of mower, you should always mow in a different pattern. This cuts down on ruts, dips and low spots in your lawn. The more often you mow, the better off you are.
Golf courses mow their greens and tees every day.
Some mow them twice a day. Fairways are mowed every 2 to 3 days. Homeowners usually mow once a week. During the summer, I cut it twice a week or more. It still turns brown a dies back if I let it grow a little too long.
