Your lawn should be cut every week. This is to ensure that you meet the recommended cutting length of one-third of the leaf glade of the grass. It is recommended that you only cut this top third and that you never cut more than this.
With this in mind, once a week is ample in terms of how often you should take out your lawn mower or garden cutters.
That being said, this does depend on the desired length of your lawn. Of course, some people like a longer length than others, and so may cut their lawn just once every fortnight.
You may also find that the length of time needed between each cut differs depending on the time of year and the type of grass.
For example, if you have warm-season grass in your lawn then you can expect growth spurts over the summer which will require more cutting, and less growth in the fall and winter, resulting in less cutting.
Likewise, if you have cool-season grass in your lawn then you might expect to cut it more often in cooler months like spring and fall, and less often in the summer.
With this in mind, if your grass is thriving in one particular season, for example, a warm-season grass thriving in the summer, then you may well find that your grass is at dizzying heights in just 4 or 5 days. This may mean that you need to cut the lawn more than once a week!
It is important, then, to bear in mind that you should always leave 2 to 3 days in between each cut at the very least to ensure that it meets that one-third rule we told you about earlier.
