How Long Does It Take Grass To Grow? (Find Out Now!)

How Long Does It Take Grass To Grow

Watching grass grow isn’t exactly the most thrilling thing on Earth. In fact, the action is actually used as a way to talk about things that are boring—like watching paint dry. Unfortunately, there are moments where you might actually try to watch your new grass grow, simply because it seems to be taking so darn long. How long does it take for standard grass to mature, anyway?

It can take between seven to 30 days for standard seeds to germinate (also known as sprout). From there, it can take between four to eight weeks for your grass to grow to maturity. This means that you should expect to see your lawn grow to its full extent in eight weeks.

Getting your grass to full fruition is a must, but patience is key. If you’re wondering how long you should wait before you worry, this guide might be able to shed some light.

How To Find Out How Long It Should Take For Your Grass To Grow

Are you looking to time out your grass, or at least gauge when you should see the fruits of your labor complete? If so, you’re not alone. Most people get a little curious about how long it could take for them to see their grass fully mature. Here’s what you need to know about grass and its growth patterns.

  • The easiest way to figure out the waiting period is to look at the seed bag. Many, if not most, seed companies will add notes about the grass strain on the bag. This will include the germination time period as well as the maturation time period.
  • You can also research the specific grass strain online. If you know the name of the grass strain, you can search it up online to get the full details on it.
  • If you’re not sure of the grass type, then it’s best to assume your grass will fully mature between six to eight weeks. If you’re just worried about the germination period, you should expect it to happen within two weeks for most strains, with more “difficult” strains taking up to 30 days.

How Can You Tell If You Should Be Worried?

There usually isn’t any reason to be worried about your grass’s growth, since the vast majority of seeds are not duds. Assuming that you planted the right type in the ground, chances are that your grass will grow perfectly fine. If you notice your grass growing in patchy or if your grass hasn’t grown within four weeks, you might have a problem.

What Should You Do If Your Grass Doesn’t Grow?

It’s rare to see moments where you plant an entire lawn, only to see nothing in return. It still does happen. If you’ve had this occur with your lawn, here’s what you need to do:

  1. Check to see if you can trace any reason why your grass didn’t grow. Did you sow it properly? Did you grab the right fertilizer mix? If you can nail down a reason why, skip step two. Otherwise, you may need to assume that you’ve got a bag of bad seeds and go to step two.
  2. Contact the grass seed company (or sod company) and explain to them what happened. Most suppliers have a guarantee, so if you call them, you can get a replacement bag.
  3. If there are any reasons why you may have been unable to grow grass, fix the problems before you try again. This can include anything from adding starter fertilizer to learning how to properly sow your seeds. If you have environmental issues, such as a flooded lawn or extreme sandiness, you may need to ensure that your soil is growth-ready before you try again.
  4. Do a second round of seeds using a newer seed bag. Second time’s a charm! Make sure the seeds you use are fresh and are meant for your type of area.
  5. If you are still struggling, call in a pro. Professionals might be able to get down to the bottom of this if you yourself couldn’t.

What Influences Your Grass’ Growth Rate?

Even if you use the same bag of seeds for multiple areas, you might see grass grow at startlingly different rates. Sometimes, you’ll see it sprout up fast, other times, it may take a worryingly long time. There are several things that can influence your grass’ growth rate. These include:

  • Watering. Most seeds will need ample amounts of water in order to ensure they germinate. This is why the best thing you can do for grass seeds is to water them three times a day for the first week, then twice a day the next, then work your way to a regular watering schedule.
  • Fertilization. Nutrients are a must for any plant, and that includes grass. If you want your grass to grow fast, this is a good way to do it. When fertilizing your lawn, make sure you kick off your seed’s growth with a starter fertilizer and finish it with some milogranite if necessary.
  • Soil Quality. Though most areas are great for grass, there are parts of the country that just don’t have the right soil for grass. Or, more accurately, they won’t grow grass well without some serious preparation. Sandy soils, rocky soils, and clay-heavy areas may have a hard time growing.
  • Seed Quality. Seeds that are old, rotten, or just not that good might take longer to grow. Though rare, it is still possible to buy a “dud” bag. If left in storage too long, grass seeds can go bad.
  • Weather. Most grass will have an optimal temperature and weather range that works well for it. To find out what temperatures work with your grass seeds, check the bag or search up the strain online.

How Extreme Weather Can Impact Your Grass Growth

If there’s one thing that you probably have learned through our site’s articles, it’s that there are a ton of ways you can improve your lawn’s ability to grow. However, you can’t control everything. The weather that your grass experiences can make or break its ability to stay healthy and germinate.

Most grass is hardy enough to withstand cold days and heavy rains. However, if you recently had a flood or a freak snowstorm, you might need to replant some seeds to ensure you still have a lawn. Unfortunately, there’s no way to get around this. Sometimes, lawns just end up dying as a result of crazy weather. All you can do is just try to regrow it.

When Should You Worry About Your Grass’ Growth?

If you have waited for a month without seeing any results in terms of grass growth, you might have used bad seeds. Moreover, if you notice that your lawn is growing in a sparse, patchy manner, it might be a good idea to try to plant more seeds or check out your soil to ensure that you’ve rooted out disease that could be stopping its growth.

How Can You Speed Up Your Grass’ Growth?

If you’re like most people who have a lawn, you probably don’t want it to look like a large wad of brown soil for too long. That’s why it makes sense to boost your grass growth whenever possible. These tips below will help you make sure you get your grass growing fast as ever:

  • Choose a grass type that’s good for your local environment and ready to be planted within your season. Selecting the right grass is a must if you want to see a lush, healthy lawn sooner rather than later.
  • Make sure to prep your lawn for new grass by using a starter fertilizer. This will give your grass the specific nutrients that it needs in order to properly take root and sprout. More nutrition means better grass growth and a faster turnout.
  • Keep an eye on your watering schedule. Grass needs extra water during its first stages of growth and germination. To find out your grass’s optimal watering schedule, check the details on the seed bag.
  • Choose a grass type that has quick germination rates. For example, Bermuda grass is known for being able to germinate in around a week. If you live in a colder temperature, check out ryegrass, which has a similarly short period.
  • The fastest way to get grass on your lawn is to lay out sod. Sod is basically pre-grown grass, so you can see nearly instant results. If you want a fuller lawn than what sod usually does, give it an overseeding treatment.

Is My Grass Seed Bad?

Not sure if your seed quality is okay? Check the seeds for mold growth, discoloration, or expiration dates. Most seeds will start to go bad after two years of storage. If you have seeds that are five years old, you should only expect half of them to actually be able to sprout. Even then, they won’t necessarily be the healthiest.

A smart way to ensure that you grow a healthy lawn is to buy grass seeds within the month that you want to plant it. Prior to planting it, store your grass in an airtight bag, in a cool and dry place away from wildlife.

Should You Just Hire Professional Lawncare?

For the most part, there’s only so much you (or anyone else) can do to promote grass growth. Though it’s fairly easy to prep your soil, sow them, and water them, you still might want to hire a crew to take care of your lawn if you aren’t up for the work. With that said, aside from properly planting the seeds and watering them, there’s nothing a lawn crew will be able to do that you can’t either.

The only time you should really look into getting professional lawncare experts as a “must-have” is if you have tried multiple attempts at growing it with little success. This suggests that you may have an underlying soil issue that needs to be addressed before your grass can grow adequately.

Related Questions

Are there grass types that you don’t need to mow?

If you love the idea of a lush lawn that grows in a pinch, but don’t want to have to mow it constantly, you have some options you can explore. There are no-mow grass types that you can use to keep your turf green but reduce maintenance post-germination. To find a grass for your lawn that doesn’t require mowing, search up no-mow grasses like Delta Bluegrass.

Does mowing your lawn help grass spread?

Believe it or not, mowing can actually be a huge grass growth booster. This is because cutting grass helps get rid of the hormones that inhibit horizontal growth. When your mower cuts the grass blade, your grass loses the signals that tell it to stop growing. This leads to thicker, fuller grass at the base.
