Have you ever noticed brown patches on your lawn and wondered whether it’s dead or just dormant? Dead grass occurs when the roots of the grass can no longer absorb water and essential nutrients, leading to complete plant death. While dormant grass, on the other hand, is a natural response to environmental stress, where the grass conserves water and energy to survive tough conditions. In this article, we will investigate the possibility of reviving dead grass by watering and explore the factors affecting its chances of recovery.

Understanding the Difference Between Dead and Dormant Grass

Before we delve into how to revive dead grass, it is essential to understand the difference between dead and dormant grass. Dormant grass typically turns brown in color and appears unnecessarily dead, but it will recover once the weather pattern changes to a favorable condition. However, dead grass will not come back to life, and you will need to restore it from scratch.

Dormant grass is a natural response to environmental stressors, such as drought or extreme temperatures. During this period, the grass may look lifeless, but it is only conserving energy to survive the unfavorable conditions. Once the weather improves, the grass will resume growth and return to its lush green color.

On the other hand, dead grass is caused by factors such as disease, insect infestations, over-fertilization, or over-watering. When the grass is dead, it means that the roots have completely withered, and the grass will not recover on its own.

Signs of Dead Grass

The surest sign of dead grass is when you see no green grass blades growing from the soil. When you pull it, no resistance is offered, and the grass comes out effortlessly because the roots have withered. Moreover, if the ground beneath the brown grass is hard and dry, it is a clear indication that the grass is dead.

Dead grass is not only unsightly, but it can also be a safety hazard, especially if it is in a high traffic area. Additionally, dead grass can lead to soil erosion and create a breeding ground for weeds.

Signs of Dormant Grass

Dormant grass, on the other hand, has thatch laying over the soil, and the brown grass blades are interspersed with live green shoots. The soil underneath may be dry but not hard. Additionally, the dormant lawn springs back to life after rains or when irrigation is applied.

It is essential to note that while dormant grass may look dead, it is not. Therefore, it is crucial to avoid unnecessary lawn care practices such as overwatering or over-fertilizing, which can cause more harm than good to the grass.

Overall, understanding the difference between dead and dormant grass is crucial in determining the appropriate course of action to take in reviving your lawn. If you are unsure, it is best to consult a lawn care professional who can help you diagnose the problem and recommend the best solution.

Factors Affecting Grass Recovery

When trying to revive dead grass, it is crucial to address the issues that caused it to die in the first place. Below are some factors that influence grass regrowth:

Soil Quality

The soil supplies essential nutrients and moisture to plants, and its quality can affect the grass’s ability to recover. Poor soil conditions limit the grass’s ability to absorb the needed nutrients, causing it to wither and die. To improve soil quality, you can add organic matter such as compost or manure. This will improve the soil’s structure, making it easier for the grass roots to penetrate and absorb nutrients. Additionally, aerating the soil will also improve its quality by allowing air and water to penetrate deeper into the soil.

Sunlight Exposure

Grass requires sunlight to grow since it is instrumental in the process of photosynthesis. Therefore, insufficient sunlight exposure can also cause brown patches on your lawn. To ensure that your grass receives enough sunlight, you may need to trim overhanging branches or remove obstacles that block sunlight. Alternatively, you can plant shade-tolerant grass species in areas with limited sunlight exposure.

Grass Species

Various grass species thrive in specific weather conditions, and planting grass that is not suitable for your area can contribute to its death. For instance, cool-season grasses thrive in colder climates, while warm-season grasses are more tolerant of heat and drought. Before planting grass, it is crucial to research the best grass species for your area and climate. This will ensure that your grass is better able to withstand environmental stressors and recover more quickly from damage.

In conclusion, addressing soil quality, sunlight exposure, and grass species are key factors in reviving dead grass. By taking the necessary steps to improve these factors, you can help your grass recover and thrive.

Proper Watering Techniques for Reviving Grass

The effective application of water to dead turf is essential in its restoration. Below are some tips for watering dormant or dead grass:

Watering Schedule

Watering your lawn regularly is essential in improving the soil’s water retention. For dormant grass, you can water it once a week, and for dead grass, you should water it twice a day for the first two weeks to activate the growth of new grass.

Watering Depth

The correct watering depth is crucial in reviving dead grass. The turf roots should receive enough moisture to improve growth, but the water should not be too much to cause new seedlings to die off. The ideal watering depth should be one inch for both dormant and dead grass.

Best Time to Water

Watering in the morning or evening as the temperatures are cooler is the best time to water, as watering during the day can cause wastage of water due to evaporation.

Additional Steps to Bring Your Lawn Back to Life

Aside from proper watering, additional steps are essential to resuscitate your dead lawn.


Compacted soil can limit water and nutrient absorption by the plant’s roots, leading to death. Aeration involves perforating the lawn’s soil to allow for air, water, and nutrients to penetrate better.


Dead grass requires the application of needed nutrients in the correct amounts to speed up growth. The appropriate fertilizer will promote root growth, and the grass will thrive better.


Overseeding your lawn helps to thicken the grass and reduces the incidence of weed growth. It would help if you did not overseed on dead grass, but the technique can be useful to revive a dormant lawn.


It is possible to revive your dead or dormant grass with proper watering techniques and by addressing other contributing factors. Through regular watering and addressing the soil condition, your lawn can regain its lush green color. However, if you are struggling with reviving your dead lawn, it might be worthwhile to call in a professional landscaper for assistance.
