Every homeowner wants the lawn to not just be presentable but for the whole surrounding of the house to look homey.

The grass in the garden, whether you admit to it or not, is like an ornament in a sense because it adds color to the landscape. So today, we will talk about grass growth.


The Truth About Grass Growth

The answer to the question of when does grass stop growing is actually found in the seasons of the year.

Nothing could be truer than what they say that spring gives the grass a different kind of green.

As soon as spring steps in, we all automatically prepare ourselves for the mowing once a week because it is that time of the year when the whole forces of nature are in balance making the grass grow tall a week after you mow them.

During this season, you know that the grass does not stop growing.

Going on to the last stretch of summer and during winter and fall, questions on gas growth can become really tricky.

There’s a blog site called Davey which details out that grass stops growing when the temperature of the day drops to 50 degrees.

This can start during late October or early November.

This being the case, the seasons of the year tell us that grass stops growing when there is a change in air and soil temperature.

What Causes the Grass to Stop Growing?

Since we have mentioned the effect of changing air and soil temperature in grass growth, the next thing to do is to identify some of the prevailing factors behind the stop in grass growth.

eHow on YouTube actually provides a good visual for this but aside from that here are some of the factors which causes grass to stop growing.

1. Dormancy or Death

Just because grasses seem to have stopped growing would mean that they are already dead. Some of them are just dormant. This means that there are times in a year when they really stop growing because. 

According to Garden Loka, you can identify dormancy when yellow or brown patches start to be the dominant colors of the grass.

In most cases, dormancy happens during extreme weathers depending on the type of grass you have in your lawn. Some are heat sensitive and some are cold sensitive.

Before sprinkling new grass seeds over the lawn, wait for spring for you to determine whether the grass is dormant or dead.

In the meantime, the easy solution is to just water them when during very hot temperatures and to just leave them during cold temperatures since the grass will stay moist.

Ryan Knorr Lawn Care discusses the importance of dormancy in a video he posted on YouTube. Go check it if you think you need to.

2. Grass Adaptation

Grass is adaptive regardless of where you live.

Most of the time, grass stop growing because they are adapting to new environments.

They have to become dormant for a while actually protects them and they will most likely revive themselves naturally after they have adjusted.

This is the reason why when you live in cooler places, the grass stops growing during summer or when the temperature is hot because it does not have enough moist in the same way that hotter places will pave for grass to not grow during colder seasons.

In this sense, grass stops growing to revive itself (which I find very amazing).

3. Type of Grass and Air Temperature

No matter how vaguely the same grasses are, the truth is, they come in different varieties.

These varieties determine when the grass stops to grow during winter, summer or actually even both. In this case, it actually depends on your choice.

Winter types of grass like the Jonathan Green Winter Rye Grass, Pennington Annual Rye Grass and Oregon Grown Premium Rye Gulf will stop growing during summer and shall grow back again come late October.

Summer types of grass like the JRK Fescue 4, Sharp’s Buffalo grass and Zenith Zoysia Seed can quickly grow dormant from September to March because the soil temperature does not allow enough moist for them.

According to Garden Loka, grass stops growing when the air temperature is below 40 degrees Fahrenheit.

Long dormancy will occur if the air temperature consistently sets to 90 degrees. While there is some truth in these, I think that it still depends on the type of grass you grow.

So When Do I Mow?

Basing on the stated information above, mowing should be as calculated as possible.

Before you mow, you must first determine whether the grass seed you used is winter type or summer type because you have to cut them down in specific height for better growth after dormancy.

Another tip before you mow is that you have to also identify which grasses are dead and which are just dormant.

If the yellow and brown patches remained even after the supposed end of dormancy, then you better sprinkle new grass seeds to replace them because they certainly are dead.

As have been mentioned, when in doubt about dormancy or death, wait for spring.

After everything is said and done, everything boils down to the point that grass stops growing because they have to.

The good thing about knowing this though is that it gives us a heads up on actually becoming more aware gardeners most especially on the type of grass we want in our lawn or the type of grass that would survive depending on where we live.

Knowing this also gives a fresh perspective in the art of mowing and the underlying factors behind grass growth.
