How Long Does Grass Take to Grow? (Different Types)

The average time required for grass to grow from seed is between 5-30 days. This time duration varies for weather, types of soil, and a variety of grass.

From my experience, I have seen that grass seeds usually begin to germinate in less than a month. At least you would be able to see the tiny little shoots in the areas you have seeded.


In this post, I will try my best to give you a good idea about the time duration and aspects on which growing of grass depends.

What is Grass Germination

Germination of the seed occurs when the seed absorbs sufficient moisture to start sprouting. The temperature of the soil will regulate this. Sometimes the outer shell of the seed may delay the process until conditions are favorable. Grass growing is the process of sowing seed to getting the first shoots and then watching them grow from 4-6 inches. Grass usually takes time to get its first shoots. Once it gets it, then you will find them growing faster. Sometimes it grows from 2-3 inches in a month.

Factors for Growing Grass

There are some significant factors on which the whole process from sprouting to growing up to 3 inches depends. So, here are the factor om which growing of grass depends:grass-growing

1. Season and Temperature

Depending on types, grasses are grown in two seasons. Cool-season and Warm season.

Creeping grasses are mainly Cool season grass. They are sown by the end of summer or the beginning of Fall. They need a temperature of 60-70 degrees Fahrenheit. On the other hand, Bush grasses are the warm season grass. They are sown by the end of the Fall or the beginning of summer.

2. Reseeding or Replace

Before sowing grass seeds at first, just make sure if you want to reseed or replace it after sprouting. If you’re going to reseed, then just sow the seed where you want the grass to grow, grow up to collect the grain, and plant in the same land again. But if you’re going to replace, either use bed or tray where you will make the grass sprout and let them have a height of 1-1.5 inches, then just take the bed or tray and place it like a carpet to wherever you want the grass to grow.

3. Seed Quality

Seed quality is one of the major factors for growing grass. Better seeds will give better quality grass. Make sure the seeds are not broken and healthy when you collect seeds. If the seeds are not quality full, then you won’t be getting your expected amount or quality grass.

4. Preparing soil

The preparation of the soil is another major issue. Unlike other trees or plants, grass has some specific need while preparing the soil for sowing seed. The top portion of the land should be loose. The ground should be clean and free of grass cutting, weeds, broken stems or sticks, leaves, and stones. A mixture of sand, silt, and clay will work better.

5. Nutrients for Grass

Grass needs some basic things like food. For that, we should make sure the soil has all the ingredients grass needs.AT fist check the PH level of the soil. Add lime if the soil is acidic. Nitrogen-rich fertilizers work best for growing grass. Do not use pesticides or weed killers without expert suggestions.

6. Seed Sowing and Aftercare

When you sow seeds to make sure you sow the seeds evenly. Otherwise, you won’t get the expected results in all places. Keep the soil moist. Water the land 1-2 times a day. But make sure the water does not get stuck and have proper drainage facility. After sprouting, follow the same process for watering. Let the grass grow 3-4 inches.

7. Mowing

Do not mow the grass unless it has a minimum height of 2-3 inches. At that height, the roots will be well settled in the soil. So when you mow them, there would not be any chances of uprooting. If you harvest them at an early age, there are high chances for the grass to become uprooted.

Varieties of Grass with Their Growing Time

Different grass has different germination times. There are mainly four types of grass you will find around the USA with their different germination time. I have given the information about them in the following table to help you choose your required one.


Duration of their sprouting


5-10 days

Fescue Grass

7-14 days


10-14 days

Kentucky Bluegrass

14-30 days

Tips for Growing Grass in Your Expected Time

As I have gone through the whole process, I would like to share some essential tips I would like to share with you. I hope if you follow them, you will be benefited.grass-lawn

1. See for the Season

Before bringing grass seed from the market, make sure the seeds you will be using is for that season. Because if you try to grow the warm season grass at the beginning of the Fall or the Cool-season grass at the beginning of summer, I do not think you will have proper cultivation. Your expectations will not be fulfilled.

2. Quality of Seeds

If the seeds are of good quality, there is a chance of getting the expected result quickly. Before buying, please check the seed quality. Low quality will not only give unexpectedly less amount of time, somewhat its shape, quality, and texture will also be wrong. It will also take more time to germinate. And the worst part is broken, or damager seed will not give any production.

3. Grow Grass in the Same Field

AT first, make your plan clear if you want to grow the grass in the same area you will be sowing the seed, or you want them to germinate in a different bed, and as they grow up to 3 inches, just bring them and plant them in the field. Depending on that, your bed or the area should be prepared. Because at different ages, grass needs a different level of moisture. In the beginning stage, seeds and sprouts will need more moisture than once it grows bigger. Matured hemp won’t be liked to have a field with clogged water. Instead, they would like to search for water with the help of their roots. 

4. Proper Irrigationgrass-watering

For grass, water is a significant factor. Proper watering helps to sprout the shoots from the seeds. Suitably grown hemp needs to be irrigated 1-2 times a day. But make sure the water does not remain stuck in the soil. Too much water may help the fungus to affect the grass. Again the place should not be excess dry. Or else the grass will dry out.

5. Fertilizing the Soil

Grass usually do not need fertilizers once it grows. That is why fertilizers should be given while preparing the ground. For that, at first, check with the PH level of the soil. Use lime in the soil if it is found acidic. Grass prefers Nitrogen-rich fertilizers. Cowdung may be an excellent fertilizer to use while preparing for the earth.

6. Mowing and Using pesticides

To keep the grass look good and fresh, mow them regularly. Do not harvest them at an early stage as there is a chance for uprooting. But once the grass grows from 5-6 inches, mow them up to 2-3 inches to get proper sunlight in the roots and soil. If the grass grows more extended, then there is a chance of not getting adequate sunlight. That may infect the grasses with fungus, viruses, and insects. Avoid using pesticides and weed killers without an expert’s suggestion. That may damage the growth of grass.

7. Prepare the Land Properly

Before sowing seeds, make sure the soil is perfect for growing grass. Clean the place properly. There should not be grass cutting, plastic, sticks, broken stems, stones, or pebbles in the land. Use loam soil 2/4th of the soil should be sand, 1/4th of the area should be silt, and the rest of the solid should be clay. You should loosen the upper portion of the ground enough so that the roots can quickly spread.

Mistakes to avoid for Growing Grass

Planting Wrong Seeds

To get the expected result make sure to choose the seeds depending on the season, quality of the soil, and weather. Cool-season grass seed will not give proper results for the summer season. Again Summer season seed will not give relevant results in Fall. The soil suitable for Ryegrass will not provide expected results for Kentucky grass. The seed ideal for warm temperatures will not offer a better outcome for cool weather. So before you buy the seeds, keep these factors on your mind to get a better result.

Skipping Soil Test

Before planting any tree or sowing seed-soil test is a must. Do not just overlook this step. Germination of the seed is highly dependent on this factor. If the soil is too acidic, there is a little chance for the seed to germinate. Instead, the seed will be damaged. Even if the seed germinates, then the grass will die due to the soil’s acidic character. Again the proportion of mixture of the land should be examined. If the ratio varies from the ideal one, then there is no chance to grow the grass or even germinate.

Avoid Shady Place

You need to avoid dark areas. From germination to sprouting to growing in size, grass needs proper sunlight and air. Grass makes its food with the help of the sun. You may have also seen that the plants or green in the shady zone do not grow well in your house. It somehow looks like a bald in the hair. SO whenever you choose a place for growing grass, make sure it does not have anything that will provide shade to the soil in majority time throughout the day.

Prevent the Soil From Getting Dry

For any plant around the world anywhere, it needs water. The same way grass also needs water. The land should not be dry. Make sure there is proper moisture in the ground. This does not mean the soil should always be wet or be like clay. Rather the soil should have little moisture. Make sure you water the grasses minimum 1-2 times a you see the earth has enough moisture, stop watering. So you can say it will be neither muddy nor dry like sand situation. You can simply use a pipe or shower to water the soil. This will keep the soil moisture, the grass green, and fresh.

Do Not Overseed

Do not just waste seeds by sowing all at the same place. Overseeding will not help to grow more grass. Rather it will obstruct the other grass to grow. Moreover, there should be proper spacing from one grass plant to another so that they can easily grow and have enough space to spread. In this case, you can do one thing that makes lines with ropes or mark with small sticks. Believe me. This will help you not only from saving your seed but also it will help the grass to grow properly.

Avoid Walking or Driving on Grass

Whether you have just spread the seeds or planted the grass, do not walk or ride a cycle or drive your car over that place. Walking will cause massive damage to the seeds and the grass also. Leave that place separately. Let the grass grow its way.


Question: How long does it take for grass to grow fully?

Answer: Grass needs a minimum of 2-3 months to grow fully from germination.

Question: How often do you water grass?

Answer: It is better to water your grass 1-2 times a day in the regular season, 2-3 times during the dry season. But it is better not to water during the rainy season as well as get water naturally.

Question: How do I speed up grass seed germination?

Answer: If the seed gets proper water and the temperature is a little high, you can speed up the grass seed germination.

Question: Will grass seed grow if you just throw it on the ground?

Answer: Yes, if you just throw the seeds, then the grass may grow. But you can not get the expected result.

Question: When should I mow the grass?

Answer: You can mow the grass once it reaches the height of 5-6 inches.
