How often should you mow your lawn?

Determining the right frequency in which you mow your lawn depends on the season. In states like New Jersey, the end of October to the start of March are the months you likely won’t have to mow your lawn. First and foremost mowing your lawn helps to keep your home tidy and clean in appearance.

Additionally, mowing your lawn helps to keep the grass healthy. Cutting your grass often also helps to promote the proper growth for your lawn allowing the grass to get the right amount of sunlight. Old cuttings also act as a fertilizer. Keeping the lawn from overgrowth helps to prevent common lawn pests that love tall grass; pests like ticks and fleas that could hurt your pets and family. 


What is the best time to mow the lawn?

There is actually a science to when you should and shouldn’t mow the lawn, in general the golden rule is to never cut the lawn when it is wet, it’s always best to wait till the grass is fully dry. Cutting the lawn when it is wet leads to a few issues, the first is uneven cut grass. Wet grass also ends up clumping together getting stuck in the mower. The blades of the mower can also harshly pull on the roots destroying your grass.

Aim to cut the grass after the morning dew has dried. (between 8-10 am) The second best time of the day is when the sun has peaked around 3-4 pm. Cutting the grass later in the afternoon also ensures the grass is dry, the temperature is milder, and the grass has absorbed all the moisture. 

When to cut the grass in the Spring

As the winter starts to end and spring starts to poke its head out, it’s important to look for consistent weather that doesn’t drop below 50 degrees during the day or night. Most grass seed is unable to grow below that 50 degree mark. At this time mowing once weekly is a good place to be until the summer heat and weather kick in. 

Cutting the grass in the Summer

You should expect to cut your grass pretty frequently in the summer, there’s a few factors that affect the frequency of how often you should cut the grass. These factors include: heavy rain, heavy fertilization of the lawn and of course drought.

With heavy rain and fertilization expect the grass to grow quickly so every four days should be appropriate, In general aim to mow once a week. During extreme droughts which have been affecting New Jersey more often, your grass will stop growing, at this point if you don’t want to kick up dust and make a dusty field, we advise you to not cut your lawn until the grass returns to normal and starts to grow again. 

Cutting the grass in Fall

As the temperature drops you’ll see your grass growing less and less, at this time of the year you’ll be mowing the lawn from your summer schedule to every week and half (about 9-11 days) and just like in the spring once the temperature falls consistently around the 50’s day and night grass seed will no longer grow. During this time it’s also best to focus on property clean up projects such as tree trimming/removal and yard cleanup work.
