How Often Should You Mow Your Lawn in Morris County?
Mowing frequency changes with the season, the weather, and the grass type. Here's how to think about it for a typical Morris County property.
Mowing frequency is one of those things that changes a lot through the year. The right answer in May is not the right answer in August — and the right answer in August is not the right answer in October.
Here's a practical month-by-month view for Morris County.
March – April: prep, then weekly
Early March is usually too early to mow — the grass has not really started yet, and stepping on a frosted lawn can do more damage than waiting two more weeks.
By late April, weekly mowing kicks in for most properties as cool-season grasses move into their peak growth window.
May – June: weekly, sometimes more
Peak growth. Weekly mowing is the standard; some heavily fertilized lawns can almost justify a second cut some weeks in May.
Edging matters most during this window — it is what makes a finished property stand out.
July – August: slow down, bi-weekly works
Growth slows dramatically in the heat. Bi-weekly mowing is enough for most properties. Cutting shorter than 3 inches in mid-summer is a fast way to stress a lawn.
If there is a heat wave, it is often better to skip a mow than to cut a heat-stressed lawn at the wrong moment.

Fall is the second big growth window. Weekly mowing returns, and the final mow of the season is usually shorter than your summer height — going into winter with the lawn at about 2.5 to 3 inches helps reduce matting and disease over the cold months.
When in doubt: weekly during spring and fall, bi-weekly through mid-summer, and pay attention to the weather. The goal is a consistent height — not a consistent calendar.
