Does grass grow at night during the peak of its growth period? We have all grown up believing the myth that grass stops growing altogether as soon as the daytime ends.
You will be surprised to know that grass blades continue to grow through the night, and simple measures can improve this growth.
Read through this guide to learn how grass grows at night and what you can do to accelerate this growth.

Does Grass Grow At Night?
Yes, grass grows at night continues, even at a very slow and insignificant rate. It will grow at night with the energy that it has gotten stored throughout the day from the sun, the soil, and the watering or fertilizing process.
The grass grows at night, using energy stored all day long. An average grass blade grows about one-tenth of an inch per day under ideal conditions. In most normal lawns with average levels of care provided, the average growth rate is 0.6 to 0.8 inches per twenty-four hours.
Even though most of this growth occurs under daylight conditions; however, a very minute amount of this growth also occurs during the night using aerobic respiration. This is how grasses thrive in areas with a small window of daylight during the day, even in summer, and still grows more at night as well.
Previously, it was believed that no grass growth whatsoever occurs during the whole night. Recent studies on the growth cycle of grass have concluded this to be somewhat untrue. Most grass growth occurs during daylight, when it is undergoing photosynthesis, but it will still grow in the evening time.
– Significance of Photosynthesis
The key reason why grasses don’t grow so much during night time is because of the absence of sunlight. Plants produce their food through a process called photosynthesis. They utilize the energy coming from the sun to fuel up the biochemical processes that make sugar molecules as a result.
The more sunlight your grass receives and the brighter it is, the more it grows. This is why a major chunk of the grass’ growth occurs during the daytime. This is also why grasses grow faster in areas with longer days.
However, during the night, with the lack of light for it to receive, it will grow with the sunlight that it has trapped throughout the whole day.
Note that the grass needs full amount of direct light in order to thrive, so with the absence of the latter, it will only grow with what it has trapped, and boost up the energy, and wait till the next moment to receive and undergo photosynthesis.
– Night Growing Season
The growth of warm-season grasses peaks in late spring to early summer. These grasses, which include popular varieties such as Bermuda or Zoysia, need high temperatures to hit their growth spurt that they would even start growing during the night time.
These temperatures must be around 70 to 75 degrees Fahrenheit or more during both day and night. Of course, they grow at night, but the growth rate is too slow to be properly measured.
Under the right temperatures during spring and fall, these grass types grow one-tenth of an inch per day. Nonetheless, some of this growth occurs during the nighttime because the days are usually shorter, and the growth process would continue.
Cool-season grasses do not grow very well during the hot summer because they need cooler weather to do photosynthesis. Some popular examples of cool season grasses used in the US are the various types of fescues and bluegrass etc.
– Growth In Winters
Both grass types slow down their growth during winter, daytime, and night. These grasses undergo dormancy when temperatures drop below 50 degrees Fahrenheit. The short duration of the day and decreased sunlight intensity also contribute to this slowed growth.
In southern states that do not get very cold winters, the grass might not even undergo dormancy and continues to grow.
The growth rate is very slow and almost even negligent at night. In addition to cool-growing, grasses that like colder temperatures slow down and do not grow from late fall till the late wintertime period.
Note that during very cold winters, when the temperatures fall below freezing, expect no more grass to grow. There is zero growth. Instead, the grass blades turn brown and become dormant. Annual grass types die during this time and will have to be reseeded come next spring.
How To Make Grass Grow at Night?
To make grass grow at night, you must promote soil aeration to loosen it. In addition, you must regularly fertilize your grass, you must also water it with the right amount and right time. Lastly, you must mow precisely, and pick the right type of grass to see night growth.
– Soil Aeration
You will be in awe as you see how the growth of grass accelerates by something as simple as soil aeration in the day and night times. The soil inevitably gets compacted even with moderate use, especially if you use a riding mower to cut grass.
One simple way is to use a lawn pitchfork to dig various holes in the soil. Each hole must be at least eight inches deep and five inches apart.
Note that you can use professional lawn aeration machines because they would provide far better aeration that is easier to carry out. Borrow a plug type of aerator that removes proper plugs from the soil to improve the soil.
Soil aeration and raking loosen the soil’s top layers and introduce air deep within it. The latter is due to seeing your grassroots find it easier to grow unimpeded deeper down and gain better water, nutrients, and oxygen access. You will see that it will even begin to grow overnight at a faster rate in the long run.
– Regularly Fertilize
There is nothing like a regular dose of the right fertilizer to make your grass speed up its growth, even at night! Even before you plant grass seeds, prepare the recipient soil well by raking it and adding a well-balanced or nitrogen-rich fertilizer.
This would provide a free supply of nutrients to the germinating grass seed. You will see that the seed germination rate will also improve rapidly.
After the grass becomes well-established, carry on feeding it with monthly fertilizing. Diluting liquid fertilizers does not decrease efficacy; instead, it protects the grass from sustaining chemical burns.
Most grasses only need fertilizing once a month, like liquid chemical fertilizer. Compost or manure mixed within the soil will fertilize the grass if you want to. The key is to keep a constant stream of nutrients to the grass coming so that it grows as fast as possible.
– Water at the Right Time
Right after sowing, grass needs to be watered a lot. Seeds must not be allowed to dry, and watering as much as six to seven times a day is a must, you can water it till the early evening time for the last time of that day, before the sun would set. During this initial period, use very little water, so the lawn does not get overwatered.
Once germination has occurred and grass blades cover the lawn, you need to switch your watering technique.
You man start watering less frequently and more deeply from then on. For most grass types, water only once per week and keep the sprinklers on for 20 to 25 minutes straight. The deeper your soil is saturated each time, the longer the roots grow.
Your sprinkler better reach all parts and corners of the lawn and waters everything evenly. Otherwise, the well-watered parts will grow faster than the neglected patches.
However, most importantly, it is a myth that watering at night keeps the grass growing at night. In our experience, this only increases the risk of overwatering and fungal infection, and this a key aspect to be mindful of.
– Precise Mowing Time
Regular mowing promotes the further growth of grasses, each grass has an ideal height at which its blades are the healthiest. Note that below this height, these blades cannot sustain the growth in night time as they wouldn’t be able to spread of a proper root system.
On the other hand, as it is above this ideal height, the grass blades are weaker and more vulnerable to getting trampled on and damaged. When you cut grass, its repair mechanism activates, promoting more growth.
– The Type of Grass
How fast the grass grows at night also depends on its inherent type. Take Perennial ryegrass, for instance.
As one of the fastest-growing grasses, it germinates within three to five days, and then the growth even will be seen slightly at night time.
At the peak of its growth period, even though you will have to take a mower to it almost every other week.
Even under less-than-ideal circumstances, fast-growing grasses will still show better growth rates than slow-growing ones. Other beautiful and fast-growing grasses are fine fescues and Kentucky bluegrass.
– What Is The Approximate Rate of Grass Growth In One Week?
On average, a grass blade approximately grows about an inch every week. This is, of course, after ideal environmental conditions and consistent lawn care. You should expect your grass to grow a little slower than this.
– How Much Does A Grass Grow In The Span Of One Day?
On average, a grass blade grows about one-tenth of an inch long daily. This is when its basic needs are being fulfilled and not stressed. Cool-season grasses are types of grass growing faster than warm-season types on average.
Now you know that grass grow as night as well.
Before ending this article on grass growing overnight, here are some important take-home points for you:
- Grass blades grow even at night, albeit very slowly, during the grass growing period.
- The light that grass receives during the day determines how much growth will occur at night.
- Grass types like perennial ryegrass are fast-growing by nature as their grass seeds germinate within seven days, and the grass itself needs to be mowed every week.
- The growth rate of grass decreases during the winter time because it germinates.
This article discusses some easy care tips that you can use to make your grass grow faster. Try them out consistently, and let us know how effective they were in your case, so that you would see night growth regarding your grass as well.
