People can restore their lawn by planting new grass seeds either in the whole yard or on select spots. Many who do this wonder how long does it take for grass to grow?
Newly planted grass seed usually takes around 7 to 30 days to germinate.
The germination rate depends entirely on factors like temperature, light intensity, water, humidity, and soil type.
In this article, we will briefly discuss and educate homeowners on the factors that affect the growth rate of grass and newly planted grass seed.

What Types of Grass to Overseed Your Lawn
Seed germination of grasses largely depends on the type of seed.
While sowing grass seed, owners should know about the types of the seeds, the weather condition, and the preferred season of the grass they’re planting. Some of the common seasonal grass types are:
These are very popular cool-season grasses. Under favorable conditions, these grasses develop their roots quickly and firmly attach to the soil.
Though the germination rate of Kentucky bluegrass is slower (14 to 30 days) than other species, their growth rate can become uncontrollable beyond the seed stage.
There are three types of fescue grasses – i) red fescue, ii) tall fescue, and iii) fine fescue. All these types are heat, shade, and drought tolerant.
The germination process of fescue grass is faster (4 to 14 days) than the Kentucky species.
Moderate to low foot traffic is crucial for the red fescue to thrive. The fine fescue requires less food and water than the other two types .
These grasses are not as aggressive as Kentucky bluegrass, and the germination rate is also quicker (5 to 10 days).
This grass requires attention and adequate lawn care. To maintain the attractive bright green color of perennial ryegrass, you will need to water and fertilize it every month.
This cool-season species seeds are sown in the late summer so that they can cover the yard by winter.
This warm-season grass grows aggressively. The seeds germinate slowly within 10 to 30 days.
During the winter, this grass can become brown. This species can stand drought and heat.
The warmer period of the year is the best time for growing grass, especially this one.
The seed germination process is a little longer (10 to 21 days). They prefer alkaline soil and don’t require high maintenance.
This grass is like the centipede grass in that they don’t require much lawn care as well.
This grass germinates within 14 to 28 days, and these species establish their deep roots slowly.
Once this grass has germinated, it requires low maintenance and can grow even on non-irrigated land . However, the production is indeed hard and labor-intensive.
These species are beautiful and can provide you with a tough, healthy lawn.
Both daytime and soil temperatures are important when talking about grass germination rate and growth.
Daytime temperatures between 50 and 75-degrees Fahrenheit are ideal for cool-season grass. When the temperature reaches above 85-degrees, the cool-season grass grows slowly.
Also, soil temperature should reach above 50-degree Fahrenheit to prevent and discourage dormancy.
Remember that during soil preparation, moisture is important for accelerating the germination rate of new grass seeds.
If the weather is too hot, then irrigate the land at the depth of six to eight inches to prevent the soil from drying out.
To establish a developed and firm root system, water the grasses when the land becomes dry.
Amount of Sunlight a Day
Day length will help you understand the time to plant grass seed. It’s advised that you choose a warm season grass type if you want a perfect lawn.
New grass seed germinates well in warmer regions as the sun is stronger in those areas.
To grow grass in your new lawn, you must choose the type of seed to grow according to your regional day length.
Planting grass seed in early spring or early summer is the best time for growing warmer type grasses. Fall seeding, in contrast, is best for growing cold season grass.
How Much Time Does It Take For A Lawn To Grow Completely?
After germination, it may take around 60 days to get a fresh and green yard.
Which Is The Best Type Of Grass To Grow In Cooler Regions?
It entirely depends on your preference. If you want to get a grassy lawn quickly, then we suggest you try fescue or perennial ryegrass.
How Can I Speed Up Germination?
Germination of grass takes a lot of time. You can speed up the process by keeping the soil moist.
When you plant the seeds, germination will take at most 30 days while most of the germination is between 7 and 30 days.
To boost germination, you can add a thin layer of organic mulch to cover the ground as it will help retain moisture.
After germination, the grass will grow aggressively and you will have a lush lawn within 60 days when properly maintained.
