The answer to 'frequency of lawn mowing' is that most lawns should be mowed once a week during the active growing season, which is typically spring through fall. This helps maintain a healthy, even lawn and prevents the grass from becoming overgrown. The exact frequency will depend on factors like your lawn's grass type, climate, and growth rate.
For example, cool-season grasses like fescue and bluegrass may only need mowing every 5-7 days, while warm-season grasses like bermuda and zoysia may need mowing every 3-5 days during the peak of summer. It's important to never remove more than one-third of the grass blade height at a time, as this can stress the lawn.
