7 Ways to Make Grass Thicker and Fuller

Let’s be honest here – we all want a thick vivacious lawn full of green grasses. But how do we get one? Maintaining a lawn is not a joke and requires a lot of time, effort, and of course, investment.

Sometimes even if you feel that you’ve done everything you needed to do, you might end up getting thin patches on your lawn or a thin lawn overall. Well, we’ll tell you how to fix the problem. Now, let’s discuss what are the measures you can take to make grass thicker and fuller, shall we?

What Are the Possible Reasons Behind a Thin Lawn?

What Are the Possible Reasons Behind a Thin Lawn

Before knowing what the things you can do to make your lawn thicker and fuller are, you must first know what the reasons behind a thin lawn are. Let’s look at some of the reasons why your lawn isn’t as thick and full as it’s supposed to be.

1. Lack of Proper Fertilization Schedule

Your lawn needs a proper fertilization boost every once in a while. If your lawn grass isn’t thick enough, you may not be feeding your lawn as per its requirement. You can seek expert advice if you don’t know how often to fertilize or what type of fertilizer to choose for your lawn.

2. Too Shady Lawn

Is your lawn too shady? Your lawn plants, including trees, might be blocking sunlight in your lawn, which may result in thinning of grasses on those areas.

If your lawn grass doesn’t get enough sunlight, you must consider seeding your lawn with shade-tolerant grass species.

Or else, you can also reseed the thin patches with the same grass species that the rest of your lawn has been seeded with. However, this time, consider cutting a few branches of your lawn trees and thinning out the bushes if you have any.

3. Compacted Soil

If you have kids or pets who are fond of playing on the lawn, the beating the lawn has to take might end up compacting the soil, thus, thinning your lawn grass.

Moreover, if you have a habit of avoiding sideways and walking through the lawn, the walking trail might also have thin patches of grass as the result of soil compaction.

Hard soil cannot absorb water easily. Moreover, uptake of water and nutrients via grass roots becomes challenging. If you notice such compacted spots in your lawn, you must consider aerating your lawn.

4. Do You Mow and Water Routinely?

If your answer is no, this might be the reason why your lawn isn’t thick and lively. A good lawn maintenance routine is a key to having a vivacious, green, and thick lawn.

Make sure you know when and for how long should you water your lawn. If you’ve recently newly seeded the lawn, you must water more frequently than usual.

Likewise, mowing not only results in a clean and tidy lawn, it is also essential for the proper growth of your lawn grasses. Ensure that your mower blades are sharp as blunt cuts might stress grasses, which might end up making the grasses prone to diseases and pests.

5. Disease, Pests, or Insects issue

If your lawn grass is infected by any disease or if any pests or insects have infested your lawn, you must address the issue as soon as possible before it does too much damage to the lawn.

Any of these issues might result in lawn thinning, so make sure you identify and treat the problem accurately.

How to Make Grass Thicker and Fuller?

So, how can you make your lawn grass thicker and fuller? Well, it’s not something that you can do overnight. All you need is a proper lawn care routine and some patience.

Let’s go through some of the lawn maintenance activities that are sure to enhance the growth and thickness of your lawn grass when done properly.

1. Test Your Lawn Soil 

Test Your Lawn Soil 

Testing your lawn soil can end up being incredibly useful as it helps to find out all the flaws in your lawn soil and help you take the necessary remedies before planting grass.

You can buy a basic kit from your nearby garden center to test your lawn soil, which will give you immediate results and are a lot cheaper. However, remember that this might not give you an accurate result. So, it is always better to send the soil to a lab for testing, even if it is a bit expensive comparatively.

These lab tests will show you what your soil is missing and give you the proper recommendation on how you can improve your soil. You can then provide your lawn soil with all the nutrients and amendments it requires to get a thicker and fuller lawn.

2. Overseed

If your ultimate aim is to make your lawn thicker and fuller, you should never leave any open patches on your garden.

It is very common to find open patches or lightly populated areas on your lawn. If you find such areas, the solution for this type of gardening problem is to overseed those areas. Overseeding helps us to cover those open patches and makes your lawn greener and beautiful.

However, be careful enough to overseed the same type of grass on those open patches as it provides uniformity and will look aesthetically appealing.

3. Aerate

There may be various reasons due to which there might be thinner grass on your lawn. Among those reasons, one is compacted soil.

When soils are compacted, the grass roots cannot get enough nutrients for their proper growth. So, if your lawn is facing such an issue, you should aerate the soil in order to resolve it.

You can simply aerate your lawn using an aerator or by using a garden fork if your lawn is small. After aerating the soil, the grass roots can easily get enough air, water, and nutrients and grow properly.

4. Proper Mowing

Sometimes what happens is you mow your lawn, but the grass doesn’t properly grow after mowing. It is all because if you don’t use the proper technique of mowing, it will hamper the growth of the grass.

The proper mowing helps the sun reach grass roots, which will promote the overall growth of the grass. Thus, in order to get thicker and fuller grass, you need to cut your grass low.

You should also switch the mowing direction if you want your grass to grow straight. If you continuously mow your grass in one direction, then the grass will start to grow in the same direction.

5. Feed Your Lawn

Feed Your Lawn

Feeding your lawn means adding the appropriate amount of fertilizers to maintain a healthy lawn. Your lawn grasses also require a constant supply of nutrients for their proper growth, such that they grow thicker and fuller.

Knowing the fertilizers means knowing the N-P-K ratios that are required at every stage of the growth of the grass. The soil test also helps us to know which nutrients are lagging in the soil and helps to take the necessary remedy for that issue.

Remember that applying the extra potassium to the lawn lacking nitrogen would be a complete waste. Most importantly, you should be aware of the best seasons for applying the fertilizers in your grass for the best outcome.

6. Water Routinely

Water also plays a vital role in making your lawn grass thicker and fuller. A proper watering routine helps you maintain a healthy lawn. In summer, you might notice the color of your grass changing. In such cases, you immediately need to water your grass.

You can add a garden sprinkler to your lawn to keep it hydrated. You can water your lawn any time of the day, but the best time to water your garden is early morning. If you water it in the evening and it doesn’t dry enough, it may promote various lawn diseases.

Remember not to overwater your lawn as it may make it difficult for younger grasses to grab a proper hold in the soil. You should water your lawn such that it reaches the depth of about 10cm as it is found appropriate for the proper growth of the grasses.

7. Dethatch

First of all, you should understand what the thatch is! It is the layer of the dead organic matter that sits below the grass leaves and above the soil, blocking the flow of essential nutrients necessary for the grass to grow.

So, if you see such layers on your lawn, you should immediately remove them. You should dethatch your lawn from time to time if you want your lawn to be thicker and fuller. You can hire a dethatcher if the layer is too thick to remove from the lawn.  


By now, you know what factors might be interfering with your dream of having a vivacious thick lawn, don’t you? What’s more, you know how to fix the problems as well!

Now, all that’s left to do is put your observation skills to the test, find out the core problems, fix the problems, and of course, follow a proper lawn care routine!
