Does Grass Grow Back Faster When Cut? It Depends!

Researched & Written by Craig

A major part of homeownership is cutting and maintaining the grass on your lawn. It can be tricky sometimes to get your grass at just the right length. This can often lead to the question: does grass grow back faster when cut?

No matter how big or small your lawn is, you will have to set time aside to cut your grass on a regular basis. Depending on where you live, your grass may grow faster than other places. Finding out the best method for caring for your lawn will allow you to properly maintain your grass.

Does Grass Grow Back Faster When Cut?

When properly cut, grass will grow back faster and stronger.

Typically, grass grows most vigorously during spring and summer, which often requires mowing about once a week. Depending on the size of your lawn, you will need either a push or riding mower.

To allow grass to grow back faster, you generally don’t want to cut it any shorter than two inches. Uneven grass that is cut too short can cause unhealthy growth patterns. When too short, the grass will concentrate its energy on blade development only and not the roots.

In return, the roots become shallow and are unable to properly absorb nutrients. This causes the grass to become patchy and even brown in certain areas, as it can’t grow back at a healthy rate.

Is it Bad to Let Grass Grow Too Long?

It can be easy to accidentally skip a week of mowing your lawn in summer, as life gets busy. 

When it comes to long grass, there are pros and cons. Though some neighborhoods may have restrictions on the grass and some people may find it unappealing looking, there are some benefits to letting your grass grow long. 

Long grass is beneficial for keeping weeds at bay. By the grass growing longer, there is less room for sunlight to reach the weed seeds, making it less likely for them to germinate. The more grass, the less room there is for weeds to grow.

By letting the grass grow longer, it is able to stay healthier over time. A longer blade means that grass is able to build up better food reserves and have stronger roots. This allows the grass to stay healthier and helps prevent brown spots in the summer.

How Long Should You Let Grass Grow Before Cutting?

Knowing what is the right length to trim your grass will allow it to strive and stay strong. Typically, you should wait till grass to grow to about 3-3.5 inches tall before mowing. If you just planted grass, you should generally wait eight weeks before cutting.

Around 3-3.5 inches is when you should start thinking about mowing.

It is important to make sure your grass is well established in the soil before you trim it. Cutting grass too soon can be damaging for the seedlings and can even cause some of the grass to die off. In order to thrive, grass needs time to grow before trimming it.

Is It OK To Leave Grass Clippings on the Lawn?

A problem many people face after cutting the grass is what to do with the grass clippings.

Lawn clippings can actually be healthy for your lawn as they provide nutrients for your grass and act as a fertilizer.  In fact, grass clippings can save you money on fertilizer as they are rich in nitrogen.

However, if your grass clippings are too thick they can cause mold and diseases in your grass as there is no proper airflow. Too many lawn clippings can cause diseases in your grass such as powdery mildew, Pythium blight, and Rhizoctonia, as well as brown patches.

In addition to leaving lawn clippings on your grass, you can also use them for your compost pile. Freshly cut grass clippings are made mostly of water and easily break down in your compost pile. In the process, they help heat up your compost pile and cause the other components to decompose faster. 

However, it is important to note that you should never leave your lawn clippings out in the road. Grass clippings are dangerous to motorcyclists, as they can create a slippery surface that can cause bikers to crash. In addition, leaving grass clippings in the road can clog storm drains. 

If you live in a rural area, it is also important to know that you should never give horses grass clippings. As horses can consume grass clippings much faster than grazing, it can cause several problems including founder and colic. In addition, since there isn’t proper airflow in piles of grass clippings, they can quickly grow mold which can lead to botulism.

Mowing and Maintaining a Healthy Lawn

In order to keep your lawn healthy, it is important to make sure you don’t cut your grass too short. Generally, you should allow grass to grow to at least 3-3.5 inches tall and never cut it below two inches in order for it to grow back healthy.
