Best Time to Mow
If you want the best possible lawn, it is said that its best to mow early in the morning and more often as the grass requires. Owners of healthy grass mow at least once a week on average but if you are busy, mowing every two weeks will do.
Do a Proper Mowing
Back and forth pattern should be followed if you want to do a proper mowing. The grass will clog and catch the blades if you move to slowly you might want to consider mowing as a sort of work out. If you are using a riding mower use a similar back and forth pattern and to mow around a flower bed, it is best to do two laps around the obstacle.
Mowing in a half-lap passed with the new pass overlapping the first pass will give you the best result when mowing. This seems like more work it actually takes time and energy because the mowing movement is smoother.
