Are you envious about the lush green yard of the neighborhood? Does it become a real challenge for you to obtain it? Well, the green grass does not occur in a day. They need much more than proper sunlight and water.

Other natural elements that affect the growth of grass include climate, type of land, germinating possibilities, and much more. Apart from this, you need to master in choosing the appropriate fertilizers and other aeration techniques. Well-timed and well-informed decisions make the difference between the typical lawn and the blemished one. 

The most asked question about the gardening is “when to plant grass seed?” While the answer is a little briefer than you thought it would be. Here are the guidelines that will help you to grow the green lawn. 

When is the best time to plant grass seed?

Answer to this question depends on what is the type of grass you are planting. There are categorized into two types:

  • Warm Season grasses
  • Cool Season grasses

Warm-season grasses such as Zoysiagrass, Centipedegrass, Bahiagrass, and Bermudagrass, etc. grow when the temperatures are between 70-90 degrees Fahrenheit. They are originally from the tropical regions; hence, they can only thrive in the scorching sun. They only grow when the seed is planted during late spring (After the last frost date) until early summer.

Cool-season grasses such as Perennial ryegrass, Kentucky bluegrass, and fescues, etc. grow well starting from the two weeks before Labor Day, and they build strong roots before winter. It grows in temperature between 60-80 degrees Fahrenheit. Due to the reason for more substantial rainfall and moderate temperatures, even the spring is a good season for planting these grasses.

How long does it take for grass to grow?

Usually, the germination time for grass seed ranges from 5-30 days, depending upon the climate, soil, and variety. However, developing a lush green lawn from scratch is not an easy task; it can take longer than this in case of cooler temperatures. Hence, it requires much more expertise & you need to keep patience and attention towards your lawn if you seriously want to have a lush green garden.

When to plant grass seed in spring?

Spring is a fantastic season to plant a new lawn or rejuvenate the existing one. At that time, the cool temperatures and frequent rain showers help in nourishing the grassy environment. Before an ideal heat of summer stress, the new blades of grass grow with the proper seedbed. The soil temperature is usually 45-55 degrees only. Hence, the cool-season grasses germinate with a good deal for a conducive healthy and rapid growth. 

If you are planting the warm-season grasses, then consider them for the late spring and early season. During this time, the soil is warm and also has the required moisture for the lawn establishment. Starting from Mid-April through June, it is ideal for the grass planting; however, it also depends on your living locations.

Planting grass seed in winter

Usually, during the winters, the blanket of lush grass looks muddy, patchy, and murky. But you don’t have to wait for the spring to come. People have the misconception that the soil may not be fertile during the winter.

Now the studies have proven that planting the seed in the winter will result in the proper growth of grass in mid-spring. You do not have to mow the lawn anyway, but seeding is perfect. This practice is called “Dormant seeds” – Sowing the seeds when they are inactive. 

The hack lies in the value of scattering the seeds. Because of the snowfall, the seeds get an opportunity to fix in the soil before germinating. The soil looks bare and patchy; hence, they are broadcasted, and seeds settle in the cracks and crevices. 

Planting grass seed in summer

Just like the typical flowering plants, even for grass, summer is not the ideal time. Especially the cool-season grass cannot get adapted to the high-temperatures. Also, they cannot stand the weeds and disease pressure. During this season, due to the warm stretches of days and short nights, the temperatures do not even fall and become challenging to maintain the soil moisture.

Comparatively, there is high relative humidity that occurs through the mid and late summers makes the grass germination worth. The weeds grow like crabgrass, broadleaf, and goosegrass grow rapidly if herbicides are not used. Instead of planting grass seeds in summer, there are three important things you can do:

  • Control the weed
  • Fertilize the seeds sown during spring
  • Take steps to establish the moisture

Planting grass seed in fall

Consider sowing the warm-season grass during the time of fall. You will have an established lawn before you enter the dormant winter season. However, fall also supports the growth of cool-season grass but only certain seeds that can survive dormancy. Start planting grass in fall during the beginning over the bare spots or even in the existing lawn. Use fertilizer and water quite frequently to support effective germination. But the routine needs to continue with the second round of fertilizer after the third or fourth week of growth. 

Relatively the germination is slow in the fall. Hence, adequate addition of water and nutrients becomes necessary. Instead, it is highly recommended not to wait too long in the fall as there won’t be any time for the grass to mature state before the dormant season. Early fall is ideal for the warm season seeds and mid-fall for the winter when their temperature is maintained at 65 degrees Fahrenheit. 

When to plant Bermuda grass seed?

Bermuda grass is one of the warm season turfs that is ideally planted during the late spring or early summer. Usually, when the soil temperatures are consistent and more than 65 degrees Fahrenheit, it grows phenomenally well. However, root growth is an essential factor for the grass. Hence, the soil temperature is always to be maintained only between 75-80 degrees Fahrenheit. The day time air temperature also plays a vital role, and it needs to be warmer than usual. 

When you plant Bermuda grass seed, always cover them with an adequate amount of soil or mulch. When it’s bare open and soil surface with no protection, it won’t germinate well. Overseeding may cause damage to the already existing lawn. 

When to plant grass seed in PA?

Pennsylvania climate is known for the fresh soil and lush green gardens. There are no many complications involved in growing the grass over here. However, it is found that they are more amenable to the cool-season grass. Mostly fescue and bluegrass are commonly grown well as they take advantage of the cool nights. All you need to do is plan the grass seed in PA during the spring and fall.

Also, warm-season grasses need necessary heat and warmth through the germination. It may not be suitable for the state of Pennsylvania. No later than October is preferable to sow the seeds. It will give the time for the two cold seasons for the excellent establishment on the lawn. 

When to plant Bahia grass seed?

Bahiagrass is perennial grass that grows in the low-level suitable for the muddy soils and shady regions. The roots get deep and can withstand drought. Hence it is one of the warm-season grasses planted during the mid-spring or early summer. During the May month, the soil will be at the right temperature.

It is always recommended to fertilize them just before the seedling as it will promote growth despite the weeds. You need to prepare the seedbed before sowing. The land needs to tilled, rolled, and fertilized to stand the heat and get the quality lawn. 

When to plant grass seed in Michigan?

Michigan is located in the northern region of the United States. All the cool-season grass grows here on the lawn. Notably, Kentucky bluegrass and other fescue type lawns suitable for the sports fields are developed here. People take care of their lawns well even though the maintenance is quite high because of the landscape.

The spring is when the grass seems to grow longer and form mature lawns. But unfortunately, during the summer, the grass may not be able to bear with the heat. Hence fall seeding is most preferred. It minimizes the danger of heat injury. If you are in Michigan plant trees within the week of Labor Day, you can find the backyard filled with the thicker turn in winter and highly progressive in springs. 

When to plant grass seed in NJ?

It becomes easy to answer the question. There is no complication. Remember that you need to plant grass seeds between August 156 and October 1 only. New Jersey is known for its warm land with mild humidity throughout the year.

It makes it easy for the warm-season grass to grow well. They adapt naturally to the environment and helps in germination, which occurs in the later summer or early fall. It is precisely when the soil is typically warm, but the temperature is cold. Try sowing seed in late summer and find the thick and dense grass lawn. Perennial Ryegrass and Tall fescue are traditionally grown here because it cost them less maintenance.


Does it seem like a lot to remember? Don’t worry! You are not alone. The time matters for the growth because the grass grows thicker, stronger, and faster when you align them on the right season. Every seed has a natural period for active growth.

Similar to any other plants at your backyard, even the lawn grasses vary when it comes to the growth cycle mainly because of the climate and the region. Therefore, whenever you have decided to make a beautiful lawn, ensure you have planned when to plant grass seeds.
