When Does Grass Stop Growing?

Sharing is caring!

There will come a time when you will probably want to store your lawnmower during the year. During the winter season, they do not want to be outdoors in the cold. According to the season, you’ll know how the lawn will look like. In the spring, you should mow the lawn at least every two weeks.

As summer approaches, you’re probably wondering When Does Grass Stop Growing?. Everybody gets to the point where they are set to put the mower back in the shed and stops in the remaining part of the year.

But in winter, you suddenly stop mowing grass, the reason being the grass sometimes stops growing during or before the winter months.

When Does Grass Stop Growing?

The grass stops growing when the temperature is very hot or high and if it does not receive sunlight because of snow, short winter days, or even leaf cover.

Also, it will stop growing if the soil temperature is about 5°C. When the soil becomes cold, the grass becomes dormant and goes into a hibernation state until the climate warms up again.

When Does Grass Stop Growing

The grass needs sunlight, nutrients, and moisture to grow. The optimum soil temperature for the grass to grow is between 18 and 24 °C; below 18°C, it will slow down, and below 5°C, it can stop growing completely. The lack of nutrients and moisture can kill the grass, but it cools the seasonal grasses.

Their roots need water and air but can stop growing if they are absent. When saying that the grasses do not grow, we are not saying they are dead. It simply means it has stopped growing for a while.

Even if the grass looks dead, do not rush to plant new grass seeds. Wait for spring, and you will see how it will keep growing.

The grass grows when it receives all the necessary nutrients in addition to sunlight, water, and heat. If your lawn is not getting the success it needs, you will find that it will not grow.

The answer after the grass stops depends on various factors. This depends on the type of lawn, for example, the warm or cool season.

Factors to Decide When the Grass Stops Growing

Grass-type

For some people, it becomes a surprise because they don’t know whether there are various types of grasses. However, this is the crucial factor because it determines whether the grass will stop growing in summer or winter. And yes, the grass may even stop growing in summer.

Different types of grass include warm, which becomes the first step to determine when you no longer need a lawnmower. For cool-season grasses, stop growing in summer, but continue during the winter months.

Typically, these grasses include Ryegrasses, Kentucky Bluegrass, and Fescues. They start to grow in November or October, but they will go to dormancy when the hot summer starts.

The warm-season grass grows in summer but is dormant in winter. These types include Bermuda grass, Zoysia grass, and Buffalo grass.

These grasses love hot summer days, though they require enough water to thrive. The dormant state may last between March or April and September or October.

Another thing to talk about consider the transition zone. It is a hot zone in the summer and very cold in the winter. Some types of grass can thrive in the climate of your choice but a transition zone. Find the type of grass you know when it stops growing.

Soil and Air Temperature

Knowing the soil and air temperatures is paramount when you decide when the grass stops growing. Some grasses stop growing if the air temperature is 40° or below.

However, other species stop growing when the air temperature exceeds 90°. For the cool-season grasses, the right growing temperature is about 50 to 80°.

They can stay green even when the temperature drops below 50°. However, it stops growing when the temperature goes below 32° for a long time.

The warm-season grass grows at 80 to 95°. They will turn yellow or brown when the temperature goes below 50° and stay there for a long time.

However, it is also important to consider the temperature of the soil. The soil may not adapt immediately to changes in temperature, like the air.

Do not expect the warm-season grass to stop growing once the air temperature has reached 50 degrees. Wait a few days for the soil temperature to adjust.

This is true even if you wait for the grass to grow back. Although you can feel the warm air outside, the soil on the lawn may still be cool, so this is why the grass has not started to grow yet.

Purpose for Dormancy

Depending on where you’re living, the grasses will stop growing for various reasons. If you are living in a cooler area, the grasses will adapt to these temperatures. During prolonged periods of heat, they will stop growing since there is not enough water for active growth.

With the warm-season grass, people can notice the opposite. Typically, this grass type becomes dormant in cold climates and dies naturally. In any case, this is not a problem as the crown of the grass will survive.

If you discover dormancy during a drought, more watering can fully revive the grass and awaken it from stopping to grow. If watering does not work, don’t worry.

The dormant period is natural for different plants, including grass, and is designed to protect the grass. Essentially, it is more likely to grow back once the weather goes to normal.

The Grass Adaptation

Depending on where you’re living, the grasses will stop growing for various reasons. If you are living in a cooler area, the grasses will adapt to these temperatures. During prolonged periods of heat, they will stop growing since there is not enough water for active growth.

The dormant period is natural for different plants, including grass, and is designed to protect the grass. Essentially, it is more likely to grow back once the weather goes to normal.

Do Grasses Really Stop Growing or Slow Down?

Although the grasses can appear to stop growing in the winter, your lawn is probably growing very slowly. The healthy perennial grasses, like red fescue, tend to grow but in small amount during the winter months.

Instead, annual grass species, like annual ryegrass, no longer grow fully in winter. They die and must be sown again. If the weather is cold, the grass will grow less.

For example, if you live in the north, you will probably not notice grass growth in January and December.


Conclusion

Mowing the grass is the sign that summer is coming. Since this is a task that many homeowners will not be concerned with for a long time, the time it takes to maintain the grass will drive you crazy in some months.

Those living in states found on the northern side expect the air temperature to go below 40°. The soil temperature must be kept constant at about 40° during the night to reach that temperature. This will help you understand when the grass stops growing.

Some of the factors to help decide when the grass stops growing include dormancy, air and soil temperature, types of plants, and plant adaptation.

If the climate is warm, the grass will keep sprouting. Normally, the threshold comes when the temperature goes below 50°F every day. Usually, that is early November or late October, but some warm zones may push the date to December.
