The answer to 'how often to grass' is that most lawns need to be mowed every 5-7 days during the peak growing season, typically from spring to early fall. This frequency helps maintain an even, healthy lawn by preventing the grass from getting too long and uneven. During periods of slower growth in the spring and fall, you may only need to mow every 10-14 days.
The ideal mowing height is 3-4 inches, which allows the grass to develop deeper roots and retain moisture better. Avoid cutting more than 1/3 of the blade height at a time, as this can stress the grass. Additionally, it's important to vary your mowing pattern each time to prevent ruts and uneven growth.
