7 Ways To Bring Back Dead Grass

7 Ways To Bring Back Dead Grass

Last updated on May 18th, 2020 at 08:56 am

Every homeowner wants a green and healthy lawn. Unfortunately, this isn’t always the case. Sometimes, the lawn simply fails to grow.

The cool thing is that there are several things you can do to bring back dead grass.

What kills grass?

Grass can die from many things that include:

Dull lawnmower

Dull lawnmower blades don’t cut the grass blades cleanly. Instead, they rip or tear the blades resulting in jagged edges.

The edges brown within a few days giving your lawn an uneven look. The jagged edges also serve as entryways for diseases and parasites that can kill the grass.

When you mow with dull blades, the grass momentarily wraps itself around the mower blades before it rips or tears. This puts unnecessary strain on the lawnmower, which can shorten the life of the lawnmower components.

Before you begin mowing, inspect the cutting blades. If they are dull, sharpen them. Grass cut with sharp blades recovers fast and is more likely to resist pests and diseases.


Pesticides, herbicides, fertilizer, and even Gasoline lead to dead grass when spilled. When you apply the fertilizer unevenly or incorrectly, it burns the grass.

Insect repellants have also been shown to burn the grass lawn when sprayed on the grass.

Animal urine

If you have a pet, whether a dog, cat, or large bird, its urine can lead to a dead lawn. Urine makes the lawn turn yellow, sometimes with a bright green ring around the edges.

Poor soil quality

It’s common to plant grass on a healthy lawn, but over time the lawn will turn yellow as the soil quality declines.


Water runs off the slopes carrying grass and young shoots with it. This leaves the ground bare and dried out. As a consequence, you have an ugly, unhealthy lawn.


While too much water will damage a lawn, so is the lack of it. Lawns need at least one inch of water every week to grow.

This can be from rainfall or irrigation. Lack of enough water leads to a dry, compacted lawn that is ugly to look at.


Sometimes the grass will get dormant. Cool-season lawns get dormant during the summer heat while the warm-season lawn will get dormant during winter.

If your lawn has a mix of grasses, you are bound to have brown patches as some of the areas go dormant while others stay green.


Lawns are affected by all types of diseases that vary depending on the type of grass. The most common ones are fungal diseases that thrive in moist conditions.

Thatch might not be a disease–it’s a buildup of decaying grass blades that build up too thick that they choke out the healthy grass.

When you let that accumulate for a long time, it brings about an impact that is synonymous to that brought about by lawn diseases.


There are plenty of insects that can affect your lawn, and they can result in a dead lawn. Some of the most common insects are the Chinch bugs that often affect the warm-season lawns.

Other insects that are bound to affect your lawn include caterpillars and many others.

You need to work with a professional who will guide you on how to check for Chinch bugs and how to get rid of them.

Ways to bring back dead grass

If your grass has started to show signs of dying, you don’t have to worry as there are several things you can do to get the dead grass to grow.

Some of the things you can do include:

#1: Water it

If your grass is dying due to lack of water, water it will come in handy at reviving it. The best time to water the lawn is in the morning (before 10 am).

At this time, its cooler and the winds are calmer; therefore, the water will soak into the soil.

At this time, the water easily gets into the grassroots before it can evaporate.

If you don’t have time to water in the morning due to a tight schedule, you should consider watering it in the evening. When doing it, ensure that you water between 4 and 6 pm.

When you water it at this time, you will give the grass blades enough time to dry before nightfall.

You should note that the later in the day you water your lawn, the higher the chances that you will have diseases on your lawn.

When it comes to the amount of water that you should use, you should apply water until its 6-9 inches of soil. Avoid overwatering the lawn as you will kill it.

There are several things you can do to tell that your lawn has had enough. The first thing you should do is to check the time it takes the soil to soak in the water.

If the lawn isn’t soaking in the water fast enough, you should stop applying the water.

#2: Weed it

Are there weeds growing on your lawn? If they are there, its time, you think about removing them. You can weed the lawn using a hand-weeding tool or weed popper.

Avoid using herbicides as they are known to cause more problems than the value they bring on the table.

All-purpose weed killers douse the lawn with chemicals that the grass doesn’t need, leading to an ugly lawn.

#3: Get rid of thatch

Thatch is a layer of dead grass, stems, roots, leaves, and other debris that are known to choke the lawn.

Thatch sits between the soil and the tips of the grass shoots, blocking water absorption.

When you remove thatch, you not only get rid of chocking grass, you also leave your lawn looking beautiful and well kept.

There are plenty of tools you can use to get rid of thatch. You can use a spring-tine rake or use the same tool you use to rake acorns with.

If you have a small yard, you can remove the thatch by yourself, but if the yard is large, you don’t have any other way out other than to hire a professional to help you out.

#4: Re-seed it

From its name, re-seeding is simply applying more grass seed to the lawn. The new seed covers the bare patches that might have been left by the dying grass.

For you to re-seed your lawn, you need to start with digging up the dead grass with a shovel.

You should then mix the existing soil with an organic humus compound to make the soil have as many nutrients as possible then plant new grass seed and top with fertilizer. Don’t be afraid of over-seeding.

You should note that the denser the new grass, the fewer the weeds it will have hence the less maintenance it requires.

After planting the grass, cover the seeded area with a light layer of peat moss. This layer seals in the moisture leaving the grass green and healthy.

How you water the seeded area greatly determines how well the grass grows. For ideal results, don’t water the area unless the top 2-3 inches of the soil is dry.

You should note that over-watered lawns develop deep root systems, which exposes them to plenty of pests and heat stress.

In the event, weeds come up, remove them by hand. You can also use a weed-popping tool to remove them. Again, don’t use chemicals.

You should limit foot or pet traffic over the seeded area until the grass reaches a substantial height.

#5: Feed it

Nothing has been shown to revive dead grass as fast as fertilizer. While the fertilizer is highly effective, you should be cautious about how you apply it.

As a rule of thumb, ensure that you only apply it once the grass is growing.

Don’t apply it on newly sown grass seed or turf as it will turn brown.

To minimize the number of chemicals you put on your lawn, avoid using chemical fertilizers. As an alternative, use liquid seaweed.

#6: Leave clippings behind

Grass clippings contain nutrients such as nitrogen, potassium, and phosphorus, all of which are integral to the growth of a healthy lawn.

You need to mow your lawn with a lawnmower that allows you to leave the clippings behind.

Once the clippings decompose, the nutrients return to the soil, leaving you with a healthier, greener lawn.

#7: Aerate it

Other than water and nutrients, grass also needs air to thrive. There might not be a shortage of air outside, but it might fail to reach the grassroots.

Lack of air into the soil often results from soil compaction. This is when the grass, dirt, or thatch density is too thick that the air doesn’t penetrate the soil.

Obviously, without air, the grass doesn’t grow as well as it’s supposed to.

For you to aerate the grass, you need to create holes in the ground for the air to get to the roots of the grass. You can use an aerator to do it. If you have a small lawn, you can use aerator shoes to achieve it.

How to tell whether the grass is dead or dormant

When the grass is dying, it turns brown, which can be confusing.

For you to avoid wasting time and resources trying to bring back grass that is completely dead, you should do your research and know whether the grass is dormant or completely dead.

There are several tests you can do:

Tug test

Here you need to find a section of brown grass, grab some of it in your hand and pull. If the grass comes out easily without any resistance, it’s most likely dead.

There is no way that dead grass will come back; therefore, you should start thinking about re-growing your lawn.

Pay attention to patterns.

You need to observe whether it’s the entire lawn that is brown or there are distinct patches of brown grass.

If the entire lawn is the same brown color, the chances are that the grass is dormant. If there are areas of circles of brown grass, these areas might be dead.

If this is the first time you are having issues with your lawn, you should consider working with an expert who will help you out.


By watering, you can tell whether your lawn is dead or not. When you water dormant grass, it will become green again, but dead grass will remain brown.

What if the grass won’t come back?

If the grass is already dead, you don’t have any other way out, other than to replace the old lawn.

Start with removing the old lawn. You can use solarization or herbicides.

Solarization makes use of the sun’s heat to kill the old grass and cooking it. For you to get the most from the process, you need to cover the entire lawn with clear plastic.

Herbicides kill roots, weeds, and grass. They can also harm you if you arent keen when using them.

For ideal results,  carefully read the instructions given on the label.

After removing the old lawn, prepare the area for new grass, aerate the lawn, and apply compost on it.

The new lawn needs to be moist, but you should avoid applying too much water on it.

Water the lawn 5 minutes twice each morning for the first 2-3 weeks. You should then water it once a day in the morning for 10-15 minutes until new grass shoots develop.

When the new shoots reach about 1 inch tall, spread a lawn fertilizer containing slow-release nitrogen.

The best way of fertilizing the lawn is by using the slow-release formula. This is to avoid burning off the grass before it can mature.

It’s common to find that some areas don’t have enough grass. In such a case, you don’t have any other way out, other than to re-seed the lawn.

For you to save time, you should use sod instead of seeds. Purchase rolls of sod that fit the entire lawn area, unroll them, then water the lawn thoroughly. Water the sod daily to keep it moist for 2-3 weeks.

The other time you should water it is when the soil starts to feel dry.

Continue maintaining it by mowing it properly, applying the right amount of water, fertilizing it, aerating it, and doing all the other things that will keep the lawn in perfect shape.
