How Long Does It Take for Grass Seed to Grow

Grass seed growth is highly dependent on the temperature, humidity, and the soil. If you are looking to buy grass seed online and wondering how long before seeds grow, this article will point you in the right direction.

Grass Seed Takes Anywhere From 10 Days To 2 Months To Grow.

Grass seed takes anywhere from 10 days to 2 months to grow. This depends on the type of grass, the weather conditions, and the amount of sun it gets.

Grass seed is a small grain that can stay dormant for years before germinating. Once it does germinate, however, it grows quickly. Grasses are a type of plant that has rhizomes (underground stems) that grow horizontally in a network. The rhizomes send up shoots and spread out as they grow along the surface of the ground.

Once the seeds have been planted, they will begin to sprout within days or weeks depending on how warm it is outside and how well they’ve been watered. If you’re planting grass in springtime or summer, you should see growth within several weeks (10-14 days). If you’re planting in fall or winter, wait at least 30 days before expecting any results

You Should Water Your Lawn At Least Once A Day.

The grass seed you plant should germinate in a few weeks. Once the seeds have germinated, they will grow into a thick carpet of new grass that can be mowed down to ground level once it hits about 1/2 inch in thickness.

You should water your lawn at least once a day for the first week or so after planting the grass seed. After that, you’ll need to water once or twice per week depending on how hot it is outside and how much rain you get. If you live in a dry climate, then you may need to water every day during the summer months.

You should water your lawn at least once a day. If possible, try to water before 10 a.m., because this is when the ground is at its maximum moisture level. Watering in the evening can create fungus and other diseases in your grass.

You should also avoid watering on windy days, as this can cause the water to run off and not soak into the ground.

If you don’t have a sprinkler system, you might consider installing one if you want a lush lawn quickly.

You Should Expect to Put Down Multiple Layers Of Grass Seed.

When you’re starting from scratch with a new lawn, you’ll need to put down multiple layers of grass seed. This way, the grass has time to grow before the weather gets too hot or cold.

You should expect to put down at least two layers of turf-type tall fescue — one in early fall and one in late spring — and three to four layers of Kentucky bluegrass.

The more time you give it, the better your chances are that the seed will germinate and grow into a lush, green lawn.

You should expect to put down multiple layers of grass seed. The first layer is the most important and needs to be watered consistently for at least two weeks.

It’s important that you water the new grass daily until it becomes established, which usually takes about a month. You will need to water every day during this time frame.

Once your new lawn has become established, it should only need watering once or twice per week.

Your Yard Is Too Shady to Grow Grass If It Has Less Than 6 Hours of Sunlight.

If you live in the suburbs, your yard may be too shady for grass to grow. If you have trees or other overhanging structures, then you will want to take them into consideration when planting your seed.

The amount of sunlight that reaches the ground is called “shade factor.” If there are more than 6 hours of shade per day, then you are considered to have a low shade factor. However, if there are fewer than 6 hours of sun per day then you have an extremely high shade factor, and it is not recommended that you try and grow any type of turfgrass in this area.

  • Your yard is too shady to grow grass if it has less than 6 hours of sunlight.
  • You can have a lawn in shade, but it won’t be lush and green. If you want to play in the shade, you’ll need to find a ground cover.

Grass seed will take at least 8 weeks to germinate, depending on the temperature and moisture conditions in your yard. Here’s how long it takes:

  • Germination: 2-3 days
  • Radicle emergence: 7-10 days
  • First true leaf: 10-14 days

More Sunlight Means Faster Growing Grass.

The amount of time it takes for grass seed to grow depends on a few factors. The main one is the type of grass seed you choose to use. Some types of grass seed are more sensitive than others. For example, Kentucky bluegrass can take up to three weeks before it germinates and begins growing. On the other hand, rye grass needs just one week before it starts growing.

Another important factor is sunlight. More sunlight means faster growing grass. If your garden is in an area that gets lots of sun, then you will see your new patch of lawn grow much more quickly than if it were planted in a shady spot.

The third factor affecting how long it takes for grass seed to grow is temperature. This refers to both air temperature and soil temperature since both affect how quickly seeds will germinate and begin growing as well as how fast they will reach maturity after germination occurs.

For example, some types of seeds will take longer to germinate if they are planted at low temperatures than if they are planted at higher ones or vice versa.


With the right type of grass seed and soil, you could have your new lawn growing strong in just a few weeks. Of course, it’s good to have some patience and realistic expectations. Don’t get discouraged if the wait stretches on a little longer than expected—just keep your space weed-free and watered well, and soon enough you’ll have the start of an inviting new lawn.
