Understanding the Causes of Dead Grass

Understanding the causes of dead grass helps in devising strategies to revive a brown lawn. Here are four main factors that often lead to the death of your grass during summer.

Lack of Water

Inadequate hydration ranks as the first significant reason for grass demise in the summer months. Grass, like all living things, requires a certain amount of water to thrive. During periods of high heat and low rainfall, lawns suffer from dehydration. It leads to grass becoming brown and ultimately dying. For instance, a drought-stricken lawn reveals its thirst with grass blades that turn from a vibrant green to a lifeless taupe.

Excessive Heat

Secondly, high intensity, protracted heat affects the overall health of the turf. It isn’t just the air temperature that harms the grass; it’s also the ground temps. For instance, when the ground heats up, it can scorch the roots, depriving them of the energy they need to stay alive. A general effect of excessive heat is a dry, brittle lawn that loses its characteristic green luster.

Soil Compaction

Compacted soil constitutes another common problem that leads to dying grass. When the soil becomes compacted, nutrients struggle to reach the grass roots. The result: patches of dead or dying grass that mar the landscape. Consider how on a heavily-used path, grass tends to wither and eventually die off, because there’s a high degree of soil compaction.

Disease and Pests

Finally, disease and pests can ravage a lawn quickly if not addressed. Turf diseases often present as discolored, deformed, or dead grass, as with Gray Leaf Spot which shows up as spots on the blades and stems. Pests, on the other hand, might not be visible to the naked eye but manifest their presence through the damage they inflict. For instance, grubs eat grass roots, often causing brown, irregular patches on the lawn.

It’s vital to identify the specific cause behind the dying grass in your garden. With the cause in hand, you can take precise, appropriate action to revive your sorry-looking summer lawn, turning it back into its former green glory.

Evaluating the Damage

When it comes to reviving dead grass in the summer, an essential first step lies in correctly evaluating the extent of the damage. This evaluation serves as a framework for the rest of the restoration journey.

Identifying Dead vs Dormant Grass

Understanding the difference between dead and dormant grass becomes crucial, as each state requires a unique approach. For instance, dormant grass still holds life, it’s simply in a period of lowered activity due to extreme weather conditions. On the other hand, dead grass implies a complete loss of life, often due to disease or sustained neglect. To distinguish between the two, tug on a section of your turf. Dormant grass, although brown, stays firmly rooted, whereas dead grass uproots easily.

Conducting a Soil Test

A soil test, fundamental to assessing lawn damage, offers insights into your soil’s nutritional composition and pH levels. A balanced pH, typically between 6 and 7.5, is considered ideal for most grass types, as it facilitates optimal nutrient absorption. Healthy soil boasts an ample supply of vital nutrients like nitrogen, phosphorous, and potassium. In the event of nutrient deficits or surpluses, a soil test provides accurate data, enabling you to take the right actions, such as amending the soil or adjusting your fertilization strategy. Many local extension offices offer soil testing services, or else test kits are available at most garden stores.

Preparing for Revival

After understanding the root causes for dead grass and performing initial evaluations, the lawn’s revival phase comes into play. It includes crucial steps such as dethatching and aeration. These methods encourage healthier root growth and improve your lawn’s overall condition. Let’s delve into them in detail.

Dethatching the Lawn

Dethatching refers to the process of removing the tangled old root systems, colloquially known as ‘thatch’, from your lawn. This build-up can create a barrier that prevents essential water, oxygen, and nutrients from reaching the soil and grass roots. To dethatch effectively, power dethatchers prove useful for larger lawns, whereas a specialized dethatching rake may suffice for smaller areas. Regular dethatching, particularly in the spring and fall, assists in maintaining the lawn’s health.

Aeration: Why and How

Aeration complements dethatching by alleviating soil compaction. It promotes better drainage and allows water, nutrients, and oxygen to reach the grassroots more effectively. Punched holes throughout the lawn, courtesy of a technique known as ‘core aeration’, facilitate this process.

To aerate your lawn, manual aeration shoes or a mechanical lawn aerator can help. Irrespective of the tool you opt for, remember to water your lawn well a day prior to aeration. This step ensures the easier penetration of devices into the soil. Aerate your lawn once or twice a year, preferably during the growing season, to maintain optimal health.

Reviving Techniques for Summer Grass

Now that you’ve prepared your lawn via dethatching and aeration for the revival phase, it’s time to look into techniques that restore your grass’s health. We’ll touch upon correct watering practices, choice of fertilizer, and reseeding or overseeding methods.

Proper Watering Practices

Aim for water delivery that penetrates the soil to a depth of at least six inches. Early morning watering proves to be the most effective, this is when evaporation rates are low, ensuring maximum absorption. Deep watering once or twice a week mimics natural rainfall patterns and encourages roots to grow deeper into the soil. Keep in mind, timing and precision in watering play a significant role in the revival of your summer grass.

Choosing the Right Fertilizer

Look for a grass-specific fertilizer that’s high in nitrogen, as this nutrient promotes green growth. Your local home improvement or garden store likely carries fertilizers with ratios like 20-5-10 or 30-0-10 – both of which contain a high percentage of nitrogen. Apply this type of fertilizer about three weeks after the grass starts greening to support healthy growth. Remember, regular and correct fertilization can aid in the successful revival of your summer lawn.

Reseeding or Overseeding Tips

When dealing with large patches of dead grass, reseeding becomes crucial. When the soil temperature ranges between 50 and 65 degrees Fahrenheit—that’s usually in the early fall or spring—you can spread grass seeds evenly across the bare patches. In a scenario where you notice thin grass rather than dead patches, consider overseeding. This involves planting new grass seeds directly into the existing turf. Both methods, when done right, work towards a lusher, healthier lawn in your summer months.

Maintenance After Revival

Consistent care transformations make a difference in maintaining your now revived lawn. This maintenance phase focuses on sustaining the health of your grass throughout the summer.

Mowing Strategies for Healthier Grass

Alter your mowing habits to enhance growth of your grass. Cutting too short places stress on the grass, leading to browning during hot summer months. Raise your mower’s blade, mowing only the top third of the grass. Long grass blades encourage deeper roots, making them more drought-resistant. Additionally, sharp blades more accurately cut grass, preventing tearing that leaves grass susceptible to disease.

Ongoing Water Management

Ensuring proper irrigation aids in maintaining your lawn’s health. Restricting water during the cooler parts of the day, early morning or later evening prevents the sun’s heat from evaporating the moisture. Aim for deep watering that reaches 4 to 6 inches beneath the soil surface. This approach prompts the grass roots to grow downwards, enhancing resilience during summer. Tracking rainfall helps to avoid overwatering, as too much water can be detrimental, causing root rot and promoting weed growth.

Monitoring for Pests and Diseases

Frequent checks keep pests and diseases at bay. Yellow patches may indicate an infestation of pests such as lawn grubs, while brown patches that don’t green despite watering could suggest fungal disease. Early detection enables prompt treatment, reducing damage to your revived lawn. Consider alternative approaches, like bio-insecticides to kill pests, or fungicides for diseases. Consult a local garden center or a reputable lawn care company for professional guidance in serious cases.


Reviving your summer grass isn’t rocket science. It’s about understanding the root causes, preparing your lawn for revival, and employing the right techniques. From proper watering to using nitrogen-rich fertilizers, you’ve got the tools to bring your brown lawn back to life. But remember, it doesn’t end there. Consistent mowing, water management, and vigilance against pests and diseases are key to maintaining your lawn’s health. So, put on your gardening gloves, get out there, and give your grass the summer revival it deserves. With time and effort, you’ll be rewarded with a lush, green lawn that’s the envy of the neighborhood.
