The best moment for cutting the lawn is in the morning, between 8 AM and 10 AM. This way the morning dew already dries but the day is not yet too warm. The grass stands dry and quite high which helps to get a good cut.
That gap allows the lawn to rest quite a lot before the coming of the night.
Best Time to Cut Your Lawn
The morning dew really makes things harder. Wet grasses clump together and stick to the cover of the blades. Cutting wet grass commonly results in uneven cuts.
The wet chips can block the machine and create messy clumps on the ground. If you do not remove those clumps, they suffocate the young grass and cause brown spots.
After rain, best wait one or two days before starting to cut. Later one can cut between 8 AM and 11 AM. Try to escape the warmest hours of the day.
Cutting in the middle of the day, from 10 AM until 4 PM, is possible, but it brings a bit of trouble.
The late afternoon and the start of the evening also work well. Usually the grass already dries then, the sun shines less strongly, and teh lawn has time to rest before the coming warm day. Cutting around 5 PM works great, because everything stays dry.
As long as it did not rain.
Not always is it possible to cut in the morning. Work, rain or noise rules commonly get in the way. When that does not work, try to cut in the late afternoon, before dark.
Some grasses grow very quick and require even three cuts per week. General advice is never remove more then a third of the blades. Cutting too short stresses the plant, because it must regrow the blades.
Removing too much at once can really shock the grass.
The laws about noise are very important. In many places there are quiet times from 10 PM until 7 AM during weekdays. During weekends those quiet hours commonly extend until 8 or 9 AM.
Cutting after 8 AM on weekdays or after 9 AM during weekends and holidays is usually fine. Even so those limits change based on the region. Some areas clearly ban use of gas lawn mowers before 8 AM.
Small gardens take around 20 minutes. Lawn mowing time for a normal lawn is less than 30 minutes. For bigger areas, that takes one to two hours, try to keep a steady pace for the clippings.
During the peak growing season, from April until mid-October, weekly cutting helps to control everything. In slower periods every two weeks is enough. If the grass grows very quickly, cutting every second day or every third day keepsit under control.
