Are you interested in creating a beautiful natural lawn in your garden? But you suddenly wonder how long does it take for grass to grow? Once you start growing a new lawn seed, you may feel like it is too long for grass to germinate. Due to the fact that you are watching it every minute, you will not be able to bear the scene waiting until it becomes a green lawn. Well, it takes time for the grass seeds to germinate into small buds. It will not happen overnight in a hurry. After sprouting, the grass seeds need to complete the rooting.

So, how long does grass seed take to grow? This depends on grass species and a number of distinct factors that affect the time expected for grass development. Normally it can take at least 5 days and the longest is 30 days. Let's find out now!

How Long Does It Take For Grass To Grow

There are many important factors that determine the answer to the question 'how long does it take to grow grass?'. They include the following things:

Type of Grass Seed

The first thing to consider is the kind of grass seed that you plan to plant in the garden. There are 2 types of grasses by season:

Warm-season grasses normally sprout between 5 days and 30 days include Bermuda grass, centipede grass, Zoysia grass, and Buffalo grass.

Cool-season grasses are mostly found in the Northeast Ohio area include Ryegrass, Bentgrass, Bluegrass, and Fescue. Cool-season grasses develop faster than warm-season ones. These grasses usually grow in 3 – 14 days.

The germination duration is the period of a grass seed growing into a plant. It may vary depending on the specific type of grass seed. Below is the germination time based on the type of grass that you can find.

Cool-season grasses:

  • Bentgrass: This type of grass germinates in 10 – 1​4 days.
  • Fescue: This type usually grows in 7 – 14 days.
  • Rough bluegrass: Look for growth between 7 – 10 days after seeding.
  • Ryegrass: Usually sprouts between 5 – 10 days.
  • Timothy: This grass type usually takes between 7 and 14 days to sprout.
  • Tall fescue: This grass type takes between 4 and 14 days.

Warm-season grasses:

  • Bahia: This grass could develop between 7 and 21 days.
  • Bermuda grass: This type usually grows in 10 – 30 days.
  • Buffalo grass: This grass type will sprout between 14 and 30 days.
  • Centipede grass: Look for grass growth between 14 and 21 days.
  • Zoysia: This type will see growth between 14 and 28 days.
  • Kentucky bluegrass: Look for sprouts between 14 – 30 days after seeding.
  • Orchardgrass: This grass germinates in 12 – 24 days.

Note that all grass seeds can germinate at different times. If the maximum germination time has elapsed but the grass still no sign of sprouting, then you need to consider the causes of this before starting another sowing.

Grass Mixture

In fact, a lawn always includes a mixture of different grasses that determines the time of sprouting. Mixtures of ryegrass and red fescue grass have time to germinate in a week. Or if we combine high-quality grass species like bentgrass and smooth meadow grass, they will germinate in 2 weeks.

Grass mixtures will have a great impact on how fast the grass will grow. Some types of grass seed have the same growth rate but the quality is different altogether. Grass seed quality plays a very important role because you can choose grass seeds that grow fast, but extremely bad quality. This will waste your time, effort and money, so we recommend balancing the growth rate and quality of the grass.

Grass mixtures generally used in households or landscapes have the growth rate that is corresponding with the type of grass seed. This speed can be changed if you apply the special maintenance to slow or speed up the rate.

After you study the type of grass seed and grass mixtures, to possess rapid germination, now checked out exactly how grass grow in a particular area.


One of the most crucial factors in the grass sprouting is soil temperature. The same type of grass seed will have distinct germination durations if they are planted in different temperature conditions. If you plant Ryegrass in warm weather, it can take only 5 days to grow completely, while in cooler weather it can take up to 10 days.

To achieve proper soil temperature, it is not an easy job. Firstly, you should know what kind of grass you're growing, warm-season grasses or cool-season grasses, then you will know what the best soil temperature is. Cool-season grasses grow ideal in the middle of 60 degrees and 75 degrees F while warm-season grasses grow well from 80 degrees to 95 degrees F. Cool-season grasses work best in areas of the Pacific Northwest states, Northern, and Midwest. On the other hand, warm-season grasses will develop ideally in areas of the country with a warm climate, for example, Southern states and Southwestern.

Not to mention the water, of course, the sunlight, the ground temperature, and the air temperature are the main components that supply energy for growth of your grass.

Some points to note about the temperature factor:

  • The soil temperature is at least 8-10 degrees.
  • Weather and temperature must be well predicted.
  • The temperature should not be too cold or frosty.
  • The appropriate weather is spring, summer or early fall.
  • Grassland does not cover much weeds, mosses and pests.

If these things happen, the seed won't grow or germinate and it will certainly not work until the warmer weather condition. This results in the probability of harm to the seed, the seed being consumed or blown off, etc…

Planting Period And Preparation

As mentioned above, to get the ideal temperature you have to know what type of grass seed you are planting, then you should sow the seeds in the right season for rapid growth. Cool-season grasses should be best planted at the end of summer or early autumn. In that way, the grass has enough time to grow before the winter because of the colder temperatures. Warm-season grasses are ideally planted in late spring. In this condition, the roots will be strongly developed in the soil until the hot summer approaches.

Then, how to grow grass? In preparation for planting, you must cultivate the soil for the grass seed. Remove debris and hard rocks out the cropping area. Next, loosen the soil with a rake or a tiller. You also need to pluck out all the unnecessary plants and weed so that the grass does not lack nutrients caused by these plants. And do not forget to learn how to protect grass seeds from being eaten by birds.

Another thing to note is that you need to fertilize the starter before planting the grass. Especially, we recommend using Scotts Turf Builder Lawn Fertilizer. Each thousand square feet of the ground requires 5 to 8 pounds of fertilizer.

You require to find the appropriate amount of water to use when watering your freshly seeded lawn garden. Watering is very important for the success of the seed germination. Both situations include water shortages or water excess can prevent germination. That's because insufficient water definitely cause dry the seeds, but excessive water will ruin them. An automatic sprinkler will help irrigate a lot of water however, it can be bad for your grass seeds.

A question arises that "How much do I need to water my new grass?". To know how much water you need to irrigate, make sure that the top 2 inches of the ground should always be wet. To ascertain the moisture level, place your finger into the ground and stop when it reaches the dry area. You need to water the planting area for 2 days before sowing grass seeds.

When to stop watering new grass seed? If you notice that the water forms in the puddle or the ground feels spongy, it is a sign of too much water. You have to stop watering immediately, and reduce the amount of water on the soil in any way.

So, how often do you water grass seed?  Well, you should water the average range once a day unless the rain has kept the soil moist. If there are strong winds or hot temperatures, it is necessary to water more often. When the seedlings are formed and developing, they should be watered regularly in the initial 2-3 weeks. Make sure to keep 1 inch of top soil always wet, but not puddle. Do this task every day or increase the tempo when needed. Once your lawn has fully grown or has been cut at least once, reduce the watering frequency to twice a week, each watering only use ½ inch of water.

Watering new seeds can cause you to experience the following problems:

  • The seeds float to the ground or are washed away.
  • Grass seeds sticking to shoes that are stepping on the sowing area when you are watering.
  • The footprint of shoes printed on the soft submersible soil on the lawn.

So, you should avoid entering areas with seeds. Only walking over this location can do the ground subsidence and make the seeds deeper. If one of these two things occurs, germination might be postponed.

Below is the comparison table of top 3 best lawn mower that will help you quickly make the perfect choice.

How Much Does Grass Grow In A Day?

So, how fast does grass grow per day? The growth rate of grass depends on the type of grass, the amount of water, the weather, sunlight and other factors. If the conditions are met well, the grass will grow at a rate of 2-6 inches a month, or approximately 0.06-0.20 inches each day. But to have a green lawn as your dream, you need to be patient for a period of 3 to 4 months.

Does Grass Seed Itself?

Grasses will grow widely from seeds in the ideal conditions. Regularly cutting the grass will not make it self-sown due to the fact that the grass cannot produce seed unless it grows blossoms. Using an electric riding lawn mower will make your work faster and easier. However, some types of grass are capable of dispersing from plants on shoots growing on or under the ground.

Typically, the seed grows when the ovaries of the flower are fertilized by the pollens which are moved from the male blossoms to the female blossoms through the wind or the insect.

Some grass species can spread by rhizomes which are underground stems growing outside from the base of the plant. Some other species replicate from stolons that are lateral stems expanding over the soil from the crown at the base of the plant.

You can not imagine how fast grass grows itself. Grass species which disperse through rhizomes or stolons could cause a dense yard if they have a good opportunity to spread. In some situations, you can take advantage of this ability of grass to create a healthy lawn without sowing more grass seeds. Keep your grass to develop taller and also water regularly promoting it spread quickly.


Now that you know the answer to the question 'how long does grass take to grow?'. As you have read above, the germination period can be as short as 3 days but may also last a full month. The average time for grass seed to sprout and grow into a plant takes about 10 days. After growing, grass will continue to develop at about 2/3cm each week. It is not only determined by the type of grass and temperature that affects the growth duration. The grass growth depends on your location, weather conditions and many other factors such as fertilizers, season, irrigation and soil preparation.

Growing grass is not difficult, you just need to be patient, learn the knowledge and follow these tips, then you will have a green grassy lawn in no time! We hope this guide helps you in developing your home's landscape.
