How Long Does Grass Seed Take To Grow?

Grass seeds are essential to growing a beautiful and healthy lawn. If it’s your first time planting these seeds, you are probably wondering how long it takes grass seeds to grow.

It takes grass seeds about 10 to 14 days to grow, but this duration varies as many factors determine how fast these seeds grow.

This article has provided vital information on these factors and additional information that will be valuable to you when growing these seeds.

What Is The Best Time To Plant Grass Seeds?

According to experts, the best time to plant grass seeds is during late spring or early summer; in other words, you can plant your grass seeds between May and June.

This period is the ideal time because there will be less rainfall that will wash away your seeds after planting, and at this period, the temperature is great for your seeds to grow (about 80 degrees)

But some seeds grow best during cooler seasons. These seeds should be planted during late summer, around August, and the temperature should be between 65 and 75 degrees.

Lawn maintenance processes like the application of herbicide should be done a month before planting your seeds to prevent the chemicals from negatively affecting the seeds.

How Long Does Grass Seed Take To Grow

As mentioned earlier, results usually take about 7 to 14 days to be visible. Still, this duration depends on several factors like the type of seed used and environmental and soil conditions.

1. Type of Seed Used

In terms of germination, seeds fall under two major categories. Warm-season grass seeds and cool-season grass seeds. Warm-season grass seeds are usually planted around late spring and early summer, while cool-season grass seeds are usually planted around late summer.

Some common warm-season grass seeds include Bermuda grass seeds, Centipede grass seeds, Zoysia grass seeds, St. Augustine grass seeds, and Bahia grass seeds. Some cool-season grass seeds include Kentucky bluegrass, rye grass seeds, Fine fescue grass seeds, and chewing fescue grass seeds.

2. Germination

Different types of grass seeds take different times to germinate. And while there is an estimated time frame for this germination, it is important to know the individual germination period for some common grass seeds.


  • Sprouts within5 to 10 days
  • Low drought resistance and high water demand
  • Intolerant to extreme heat and low temperatures

Kentucky bluegrass: 

  • Sprouts within 14 to 30 days
  • Somewhat resistant to drought
  • Thrives in a fine-textured soil
  • Endures cold and is disease resistant
  • Grows on moderate sun exposure

Bermuda grass:

  • Grows within 7 to 10 days
  • Has a very high resistance to drought
  • Thrives on full exposure to the sun
  • Regenerate quickly

Centipede grass: 

  • Grows within 14 to 21 days
  • Moderate water demand
  • Grows best on exposure to full sun. However, It does okay under the shade
  • Coarse texture

Fine fescue grass: 

  • Grows within 10 to 14 days
  • Low water demand
  • Grows in thatches
  • It is not very resistant to disease, and it is prone to bugs
  • Regenerates slowly
  • Requires little fertilizer

3. Weather

The two basic weather elements that affect grass seeds’ growth are very low temperatures and heavy rainfall. A lower temperature is not the ideal state for your grass seeds to germinate, even for cool-season grass seeds. Heavy rainfall, however, can lead to erosion that can wash away your seeds.

It is important to be up to date with your weather forecast to determine the best period to plant these grass seeds. To control the erosion problem, you can use netting made of coconut fibers to keep your soil and seeds intact. Straws are another alternative to consider. These control methods will be useful in areas with a high level of rainfall.

4. Soil Conditions

The type of soil you sow your grass seeds into determines how long it might take to grow. An ideal soil should have a pH level between 6.0 and 7.2 and be moist at all times to support the growth of these seeds. Look out for pests that may inhibit growth and eliminate them in a way that will not affect your grass seeds.

5. Light Intensity

Some grass seeds like fescue thrive under the shade, while others like Bermuda grow well under full sun exposure. It is important to know the amount of light these grass seeds need individually, as it allows you to create a better environment to facilitate their growth.

How to Choose The Right Grass Seeds For Your Lawn

A healthy lawn is a common feature of most American homes, and to achieve this look, you will also need to evaluate the type of grass seeds you use.

The most important factor is going for quality seeds that will not be affected easily by external conditions; these can be obtained in nurseries and stores.

It is also helpful to study the requirements of the seeds you choose. Below are some ways you can choose the right grass seeds.

1. Perform a Soil Test 

This test is essential to determine the type of grass seeds that will grow best on your soil. A major factor of this soil test is the pH level, which has a say on what type of grass seeds will grow well in your soil. To carry out this test, you will need to follow the process below

  1. divide your lawn
  2. take soil samples from different parts of your lawn you intend to plant these grass seeds
  3. the all the soil samples and weigh them
  4. send them to a cooperative extension service
  5. wait for about 2 weeks to get your result

2. Study The Seeds

If you already have a target seed you intend to grow on your lawn, then you must know the details about these seeds.

Some crucial information to gather includes the amount of water, light, and fertilizer it needs to grow well. You should also evaluate the activity that takes place on your lawn as it helps you choose the right seeds.

For example, if you have kids playing on your lawn or this area is usually used for sporting activities, it is best to select Bermuda grass seeds as they can withstand so much without easily turning brown.

And if you usually have pool time on your lawn, your best match is a Kentucky bluegrass, as it can mend itself to fill up patched spots. But then, this grass also requires frequent mowing and application of fertilizer.

3. Assess The Local Variety of Performance Data

Take a stroll in your neighborhood and look at the lawns around you. Determine what grass seeds grow better in your area based on your neighbors’ yard type. A grass seed type populated in one area indicates a possibility of successful growth in your area.

4. Decide

After all this research, you should list the species you are considering and select one that you know will do best based on the results of your research. You should also make a budget that covers the cost of growing a healthy lawn.
