Many people want to know the answer to this question. As the seasons change, your lawn starts to react differently. The real answer to the question is that there is really no set time when to stop mowing your lawn. I will explain that shortly.
Grass Will Go Dormant
When the seasons change, it brings about a change in the weather. This affects lawns depending on the region that you live in. This simply means your lawn takes a nap to get through the colder temperatures.
When this happens, it will depend on the region you reside in, as dormant temperatures will vary.
In warm-season areas, your grass will go dormant in soil temperatures lower than 55 degrees. In the cool-season areas, the grass goes dormant at soil temperatures below 45 degrees. These temperatures must be constant and not fluctuate from lower to above the specified temperature.
Whenever your lawn goes into dormancy, it will not look appealing at all. It will be thin and discolored. It can make you think your lawn is dying in some cases. But know that as the temperatures warm up and stay steady, it will green back up. This normally starts to happen in the Spring when the conditions are favorable.
Below is a video explaining dormant grass.
When Autumn rolls around, you can expect it to be pretty much the time of year for the temperatures to start declining from hot to cold, and depending on what nature does will determine how soon the soil will reach the temperature to put your yard in a dormant state.
Speaking Of Nature…
The only thing that will really stop you from mowing your lawn is snow, the temperature, rain, or ground frost. So until the temperature makes your soil get and stay below the temperatures mentioned earlier, you will have some growth.
This means there is really no definite time to say when to stop cutting your lawn. When you might be used to having your lawn cut every 10 days to 2 weeks, you might be cutting it once a month until nature finally puts your lawn to sleep.
