Factors That Affect How Long It Takes Grass To Grow

When you doubt yourself and ask, “Really, how long does it take for grass to grow?” Just remember a few things that will change the process:

How Long Does It Take Grass Seed To Grow

Type Of Grass Seed

Of course, the type of grass seed you use will determine how long it takes to grow. Most of the grass seed we use here in Northeast Ohio is for “cool-season” plants. The best temperature for that kind of grass seed is between 60 and 75 degrees Fahrenheit.

Bluegrass, bentgrass, ryegrass, and fescue are some of the most popular cool-season grasses in Northeast Ohio.

Early spring or fall are the best times to plant cool-season grasses because the plants won’t have to deal with the often too hot and dry conditions of summer.


How long it takes for grass seeds to sprout is another factor in how long it takes for grass to grow. A seed grows into a plant through a process called germination. Different kinds of grass seeds take different amounts of time to sprout, or grow from a seed.

  • Ryegrass: It takes ryegrass seeds 5–10 days to grow.
  • Fescue: It takes fescue seeds 7–14 days to grow.
  • Bentgrass: It takes 10 to 14 days for bentgrass seeds to grow.
  • Kentucky Bluegrass: Kentucky Bluegrass seeds usually grow in 14-30 days


How long it takes for grass to grow can be affected by the weather. Cooler than usual temps and too much water from heavy spring rains are two of the most common things that slow down grass growth.

Before planting, it’s a good idea to check the long-term weather. You can’t always avoid heavy rain or temperatures that are cooler than usual.

As we already said, cool-season grass grows best in Northern Ohio when it is between 60 and 75 degrees Fahrenheit. If you plant when it’s this hot, you might get better results.

Soil Preparation And Conditions

In addition to good weather, keep an eye on the soil conditions of your grass. The pH of the soil can change how long it takes for grass to grow. Cool-season grasses do best in soil that has a pH between 6.0 and 7.2.

Water the dirt a few days before you plant grass seed to make sure it gets the right amount of water. Soak the ground up to six to eight inches deep. If the earth isn’t already wet from rain, water your grass seed once or twice a day after planting.

Don’t forget to keep an eye out for bugs in the yard. These animals can hurt the health and growth of grass. To help your grass grow faster, keep hungry bugs and other pests away from grass seed that is still soft.

Help With Growing New Grass From Grass Seed

If you want to make it take longer for grass seed to grow, think about the things above and do what you can to make the best conditions.

Plant your favorite type of grass seed when the weather is warm. If you need help, ask for it. Keep the soil damp but not soaked.

How To Speed Up Grass Seed Germination?

How Long Does It Take Grass Seed To Grow 2

It can be fun to plant grass seeds to change the way your yard looks. But sometimes it takes longer than people are willing to wait to see effects. There are a few different ways to speed up the time it takes for grass seeds to sprout.

  • Pre-germinate your seeds: Soak your grass seeds in water to make them grow and start the germination process before you plant them in the ground. This is called “pre-germination.” It is best to germinate seed mixes ahead of time because they can all sprout at different rates. When you put the seeds, they will sprout more evenly if you soak and pre-germinate them first.
  • Till and amend your soil: Till up the grass to a depth of 6 inches and add soil or peat moss to the area. You can help your grass seeds grow faster by adding a particular type of fertilizer made for lawns. With fertilizers, you can help the roots and leaves of your grass grow, which will make it look better and make it stronger.
  • Toilet paper grass: crushed toilet paper, flour, water, grass seeds, and fertilizer can be mixed together to make a slurry. The nutrients in the fertilizer can help the grass seeds grow faster and last longer. Make a layer of the sludge about ½ inch thick on the surface where you want to grow. The slurry helps the seeds stay in contact with the soil, which is useful when the ground isn’t level.


So, you planted your lawn in the best weather, in the best seedbed, with the best seed and the best mix for what you need. What else can you do to make sure it grows quickly? To help your lawn grow, you could make sure it gets watered properly.

After you plant grass seed, you should deeply water your lawn every day for the first few weeks. It will soon start to sprout little green shoots all over your yard if you don’t water it when it rains.


Will Grass Seed Germinate On Top Of Soil?

Grass seed will grow on top of dirt, yes. When you plant grass seeds, it’s best to do it shallowly so they can’t get stuck in raised areas. If you care for your seeds properly and till the earth and spread the seeds out evenly with a rake, they will have a better chance of sprouting.

How Quickly Does Grass Seed Dry Out?

If you don’t water grass seed in warm weather, it can dry out in just one day. For sure, your grass will grow past the seed stage, keep the grass seed wet during the germination stage.

This will help the grass seeds stay moist. Watering them early in the day and again after the hottest part of the day can also help.

How To Pre-Germinate Grass Seed?

To get grass seed ready to germinate, you must first soak the grass to break up its top layer. If you change the water every twelve hours, this can go on for up to five days. If you don’t have time, you can stop after three days. After letting the grass seeds soak, you can put them in the yard on tilled soil that drains well. During this time, mist or gently water the seeds every day to keep them wet. Most types of grass seed should sprout after two weeks. If a mix of seeds are used, they should all sprout around the same time because they were soaked.

Will Grass Seed Grow If I Just Throw It Down?

If you just throw grass seed on the ground or dirt, it probably won’t grow well because the seeds won’t get enough care or shade. The best results will come from tilled, well-fertilized soil for growing grass. It is worth the work to have a beautiful outdoor place.

How Long Does It Take For Grass Seed To Germinate In October?

If it’s a warm-season grass, it can take anywhere from two to four weeks for grass to grow in October. In the cooler months of late fall, cool-season plants can still sprout and grow roots, but you might not see their full potential until spring.

How Long For Grass Seed To Grow 3 Inches?

Under ideal conditions, it can take up to 30 days to see grass grow any length, possibly up to 3 inches. Then you might ask, “How fast does grass grow?” Depending on the type, most established grass grows between 2 and 6 inches per month. This means that grass grown from seeds will probably take at least a month to reach 3 inches in height, since it needs to use all of its energy to grow in the germination and elongation stages.
