How Long Does It Take To Grow Grass From Seed

How how long does it take to grow grass from seed? Too long it may seem... After you planted grass seed, you will be anxious to see growth.

No one likes to stare at bare spots or dry dirt in their yard. Lush, green grass is the perfect accompaniment to beautiful landscaping. To complete your outdoor space, you need grass.

However, it can be hard to determine when to plant for best results. More importantly, people want to know how long it will take for the grass seeds to begin to take root and grow. This can help homeowners decide when to plant their seed.

In this article, I will let you know how long for grass seed to grow, in a variety of conditions and weather. This explains why the length of germination can vary.


How Long Does It Take To Grow Grass From Seed

Planting Grass Seed in Spring

Spring is one of the best times to plant grass seeds. Spring rain showers are wonderful for grass, as it begins to emerge from the ground. This is generally when I plant my grass seed; I want to make sure the seed has ample time to set into the ground.

How long does it take for germination when Planting Grass Seed in Spring

One of the best reasons spring is good for planting is the rain. Grass seeds need to stay wet, otherwise they die. This is crucial for the germination stage, which can take 30 days or longer in cooler weather. Plan to water daily so the ground stays moist until the seeds sprout.

If you decide to plant grass in the spring, you will need to pick grass seeds that do well in the cooler seasons. One great example is bluegrass; it germinates the best in fall or spring.

You should look for C3 grass seeds. Bluegrass has a typical germinate time of 20 to 30 days because of cooler temperatures. Get your Bluegrass seed on Amazon.

If you need a quicker germination and a warm spell is approaching, there are other faster varieties. Rye grass and fescue are able to germinate in 5 to 15 days. They do best when it is warmer than the typical spring. Get your Rye grass seed on Amazon.

Planting Grass Seed in Summer

How long does it take for grass to grow when planting the seed in Summer

It is advised to plant grass in early summer before it becomes scorching hot. Summer can be a difficult time to grow grass because of the moisture requirements. The typical spring showers give way to the sun beating down and drying out the ground for weeks at a time.

When I have planted grass seeds in the summer, I find I have to water a lot more frequently in order to get the grass seed to germinate. You don’t want to create swimming pool in your yard, so it needs time to soak in before you water again.

I have found I need to water in the morning and summer in the hot Ohio summers in order to get it germinate. And using an expandable hose with brass fittings or oscillating lawn sprinkler system is the best option for watering in summer.

Summer grasses can take longer due to the excessive heat. They can take anywhere from 10 to 30 days. Spring has a larger variation in germination time because the temperatures can bounce and vary a lot. Summer temperatures tend to remain steady.

Soil Conditions For Planting Grass Seed

The condition and nutrients in your soil can make a huge difference in how long it takes for grass seeds to grow. The temperature of your soil and moisture level make some of the largest differences.

  • Clay soil can make growing grass tricky. Clay soil doesn’t heat up as quick because it is very dense. Due to the cooler temperature, germination can take longer or never happen at all. Clay also holds the moisture. This is a good thing, unless excessive rain occurs. This soil isn’t known to drain well ever. 
  • The best thing you can do is put some good top soil over the clay and this will provide the perfect enironvment to germinate your grass seed.

  • Sandy soil struggles to hold moisture. The situation is the reverse of clay soil. Sandy soil is able to heat up well during spring. If you have sandy soil, you will need more frequent watering because the water drains away very quickly.

Test Soils pH Level for Faster Grass Seed Germination

You are able to test the acid level in your soil. Soil with acidity is a good thing for grass seeds. It helps them germinate faster. Acid makes it easier for the seedlings to come out of the coating. On the other hand, too much pH can cause the seeds to be damage and, potentially, never germinate. Get a soil pH Tester on Amazon.

How Long For Grass Seed To Grow?

As you can see, answering this question depends on quite a bit of factors. The simple answer is to state it can take anywhere from 5 to 30 days. This answer is quite vague and frustrating.

There are some things to remember. If you plant in the summer and it is very hot, expect the grass seed to take up to 30 days to grow and remember to water well.

If you plant in the spring and have a warm spell, your seeds can grow quickly, maybe even 5 days! A cooler spring may take closer to the 30 day mark.

Watch the weather and look at the condition of your soil. Combining these two factors can give you an insight into whether the grass seeds will need just a week or maybe a month to grow.
