How to turn yellow grass green? (Fully Exposed)

If you’re wondering how to turn yellow grass green again, we need to first work out what is causing the green grass to turn yellow in the first place. There are several factors to consider.

The most common causes include incorrect watering, specific disease, dog urine, improper fertilization, spilled contaminants, too compact soil, and damage from mower blades. Let’s have a look at all of these problems in detail:

Watering Incorrectly and The Best Way to Water Lawn

Watering your lawn is vital to keeping it green and healthy, but many people unknowingly make certain mistakes that can lead to yellow, patchy grass. Here are some common watering mistakes to avoid and the best ways to water your lawn:

The Best Way to Water Lawn
  • Overwatering: In general, grass loves water. However, too much water can drown it out, making it more susceptible to diseases and pests. These diseases and pests can turn the grass yellow by the damage they cause.
  • Underwatering: Not giving the grass enough water can lead to dehydration, causing the grass to turn yellow and brittle.
  • Watering at the wrong time of day: Watering in the day’s heat can cause water to evaporate too quickly. Watering at night can lead to prolonged moisture on the grass, increasing the risk of fungal growth.
  • Not watering deeply enough: Light watering encourages shallow root growth, making the grass less resilient to drought. As a result, they can dry out and turn yellow.
  • Watering too infrequently: Inconsistent watering can cause stress to the grass, leading to yellowing and patchy growth.
  • Not adjusting the watering schedule to weather conditions: Watering too much or too little during periods of high or low rainfall can negatively impact the health of the grass.
  • Using the wrong watering method: Certain grass types and lawn areas require specific watering methods, so using the right tools and techniques is important. As a result, a range of the above issues can and will occur.

Now that we have a good grasp of the incorrect watering methods let’s have a look at the best ways to water a lawn:

How often should I water my lawn to keep it green?

To keep your lawn green and healthy, it’s important to water it regularly. Watering frequency will depend on several factors, including your climate, soil type, and grass species. Generally, most lawns need about 1 inch of water per week to grow and thrive.

How often should I water my lawn to keep it green

But how many minutes should I water my lawn? To determine how long you need to water your lawn, you can perform a simple test: Place an empty can or rain gauge on your lawn and run your sprinkler system for 15 minutes. Make sure that it is placed where the sprinkler can reach it.

Measure the amount of water in the can or gauge and multiply it by four to get the total amount of water your lawn receives per hour. Simple right? Now you know the exact flow of your sprinklers, you can use this as a guide to working out the amount required per week. 

So, if your lawn needs 1 inch of water per week, you’ll need to water it for approximately 30 minutes per zone twice weekly. Again, grass type, height, etc., will play a role in its growth rate and consequential recovery.

Furthermore, if you live in a hot and dry climate, you may need to water your lawn more frequently to keep it green and healthy. Monitoring your lawn and adjusting your watering schedule as needed is important.

What is the best watering schedule for my lawn?

The best watering schedule for your lawn depends on a few factors, such as the climate, soil type, and grass type. Generally, it is recommended to water deeply and infrequently rather than frequently and lightly.

This means watering your lawn deeply 1-2 times a week instead of daily, as frequent shallow watering can lead to shallow root growth and weak grass.

What is the best watering schedule for my lawn

Aim to water your lawn to a depth of 6-8 inches, as this will encourage deep root growth and healthy, green grass. Remember, strong, healthy roots encourage further growth. 

Is it better to water grass morning or night?

It is generally better to water grass in the morning than at night. This is because watering in the morning allows the grass to absorb the moisture it needs to grow and recover from any stress or damage it has undergone during the previous day.

Watering in the afternoon could see the stagnant water amplify any heat caused by the afternoon sun and burn the grass s a result. On the other hand, watering at night can create a moist environment that promotes the growth of fungi and other diseases.

Therefore, if you want to help your yellow grass turn green again, it is best to water it in the morning.

Identifying and Treating Lawn Diseases

Identifying and treating lawn diseases is essential to maintaining a healthy and green lawn. In this section, we will discuss common lawn diseases and how to identify, treat, and prevent them. By learning to recognize the symptoms of various lawn diseases, you can take proactive steps to protect your lawn and keep it looking its best.

Identifying and Treating Lawn Diseases

Common lawn diseases and how to identify them?

  • Brown patch disease: This fungal disease is often found in warm and humid weather and can cause irregular circular shaped patches that are generally yellowy brown. The grass blades will appear thin and have a sunken appearance at the center of the patch.
  • Dollar spot: This fungal disease is named after the small silver dollar-sized spots that form on the grass blades. These spots often grow and merge to form larger patches.
  • Rust: This disease creates a rust-like appearance on the grass blades that can be orange, yellow, or brown. It often occurs in dry, sunny weather and spreads quickly.
  • Powdery mildew: This disease appears as a white, powdery growth on the grass blades and is often found in shaded or damp areas.
  • Fusarium blight: This disease results from a fungus commonly found in warm weather and high humidity. It appears as yellow or brown patches and often causes the grass blades to die.

How to treat and prevent lawn diseases?

How to treat and prevent lawn diseases
  • Applying Fungicide: There are a variety of fungicides that can be used to treat lawn diseases, but the most important task is identifying the specific disease before going ahead and choosing a product. Once ascertained, follow the instructions on the label carefully and use protective gear when applying. They usually require spraying a solution onto the affected area to neutralize the disease.
  • Cultural practices: Proper cultural practices like watering, mowing, and fertilizing can help prevent and treat lawn diseases. Avoid overwatering or underwatering, as both can create an environment for disease growth. Mowing your lawn to the recommended height can also help, as long grass blades can create a humid environment that promotes disease.
    • However, allowing the lawn to gain some height is essential for a strong lawn base. Getting that ight height is essential for the longevity of the lawn. It is recommended to mow your lawn to a height of 2.5-4 inches (6-10 cms) for optimal growth. Fertilizing with a balanced fertilizer can also help keep your lawn healthy and better fight off disease.
  • Reseeding or replacing damaged turf: If you have a large area of damage, it may be necessary to reseed or replace it. Be sure to choose a grass type suitable for your climate and soil type.

Dog Urine and How to Treat?

Dog urine can turn grass yellow or brown due to its high concentration of nitrogen and salts. An excess of these 2 minerals specifically will scorch or burn the grass. To treat dog urine damage, you can simply flush the affected area with water to dilute the urine and prevent further damage. 

You can also apply a soil amendment such as gypsum to help neutralize the salts in the soil. Additionally, reseeding the affected area or replacing parts lacking with fresh sod can help restore the lawn’s appearance. It may take some time, though, so plan accordingly. 

To prevent future damage, you can try training your dog to urinate in a designated area or provide them with access to water to dilute their urine.

Fertilizing Incorrectly and The Best Way to Fertilize Lawn

Incorrect fertilization can cause the grass to turn yellow due to nutrient imbalances. Over-fertilization or using the wrong type of fertilizer can result in more than certain nutrients, which can cause a build-up of salts in the soil. 

This can make it significantly tougher for the grass to take in water and other essential nutrients. It can lead to a condition known as fertilizer burn, which causes yellowing, browning, or even death of the grass. 

Fertilizing Incorrectly and The Best Way to Fertilize Lawn

On the other hand, under-fertilization can result in a lack of essential nutrients, such as nitrogen. This causes the grass to become yellow and stunted in growth. Proper, balanced fertilization is crucial for maintaining a healthy and vibrant lawn.

The best way to fertilize a lawn is to apply it at the right time and in the right amount. Every grass type will have different nutrient requirements, so it’s always a good idea to do some research on all of your fertilization options before even purchasing to ensure that you aren’t putting your lawn at risk of any further damage.

Common mistakes people make when fertilizing their lawn

Some common mistakes people make when fertilizing their lawns include:

  • Applying too much or too little fertilizer
  • Not following the recommended application schedule.
  • Using the wrong type of fertilizer for their grass type
  • Failing to water the lawn after applying fertilizer

Choosing the best fertilizers for different types of grass

The best fertilizers for different types of grass can vary, but generally, a balanced fertilizer that contains nitrogen, phosphorus, and potassium is a good choice. Choosing a fertilizer with the right nutrient balance for your specific grass type is important because some grow thicker, some faster, some have deeper roots, etc. So, it’s important to meet the need of the type.

Choosing the best fertilizers for different types of grass
How to choose the right fertilizer for your lawn?

To choose the right fertilizer for your lawn, you should consider factors such as your soil type, the climate in your area, and your grass type. A soil test can also help determine what nutrients your lawn needs. Then simply head down to your gardening specialist with the information and discuss your options. 

What is the best fertilizer for yellow grass?

If your grass has turned yellow, the best fertilizer to use will depend on the cause of the yellowing. A nitrogen-rich fertilizer may be the best choice if the yellowing is due to a lack of nitrogen. However, a different type of fertilizer may be needed if the yellowing is due to other factors, such as soil pH or nutrient deficiencies.

The best way to determine which fertilizer you should use is by taking a soil test. They can help identify the cause of the yellowing and guide you in selecting the best fertilizer. Unfortunately, there is no one size fits all answer to this question. 

Spilled Petrol or Chemicals and How to Treat It?

Spilled petrol or chemicals are another common cause for green, healthy grass to turn yellow. The damage may appear as irregular patches or lines.

The chemicals in the petrol or the chemicals themselves can cause the grass to die, which can even affect deep down within the grassroots. To treat petrol or chemical damage, it’s important to act quickly. 

Spilled Petrol or Chemicals and How to Treat It
  • Firstly, remove any contaminated soil and dead grass from the affected area immediately.
  • Then, aerate the soil to help it recover and apply a high-quality fertilizer to promote new growth. 
  • Water the affected grass to dilute any remaining spillage and help the fertilizer work its way into the soil below. 
  • If the damage is severe, you may need to reseed the area or lay new turf. 
  • To prevent damage such as this from happening, always store chemicals and petrol in a safe place away from your lawn. Also, try to be as careful as possible when using them to avoid any spills.

How petrol and chemicals damage lawns?

Spilled petrol or chemicals can cause the grass to turn yellow and die quickly, as they are toxic to plants. If not dealt with, this can result in large areas of dead grass. The severity of the damage usually depends on the type and concentration of the chemical and the amount spilled.

How to treat and repair petrol and chemical damage?

To treat and repair petrol and chemical damage on a lawn, you can do the following:

How to treat and repair petrol and chemical damage
  1. Thoroughly water the affected area immediately to dilute the substance and minimize its absorption by the roots. 
  2. Proceed by removing the contaminated soil and replacing it with fresh soil.
  3. Additionally, applying activated charcoal or biochar can help absorb any remaining toxins within the soil.

How to prevent damage from petrol and chemicals?

To prevent damage from petrol and chemicals, always store and handle these substances carefully and avoid spilling them on the lawn. Try to use them somewhere where they can be mopped up and cleaned in a safe environment. If a spill does occur, try to contain it and clean it up as quickly as possible to minimize the damage.

Fixing Compacted Soil

Compacted soil can turn yellow grass by preventing the roots from accessing nutrients, water, and oxygen. When the soil is compacted, all the tiny spaces between soil particles are reduced, which makes it difficult for roots to grow and penetrate the soil.

As a result, this can lead to shallow roots and yellowing grass. To prevent and treat compacted soil, you can aerate it to loosen it up and improve the movement of air, water, and nutrients in the soil. Aerating involves:

  • Punching the soil with small holes.
  • Allowing the roots to spread and take up nutrients.
  • Resulting in a healthier and greener lawn.

There are some pretty handy pieces of machinery you can hire or purchase to do the job. In less severe cases, there are specially designed shoes with spikes that can have a similar effect.

Using Mower with Sharper Blades

A sharp mower blade is essential for maintaining a healthy and vibrant lawn. Dull mower blades can cause grass blades to be torn, leaving them open to disease and discoloration. This can lead to yellow grass and overall damage to the lawn. Using a mower with sharp blades can help ensure the grass is cut cleanly and evenly, reducing the likelihood of yellowing or browning.

Using Mower with Sharper Blades

How to sharpen mower blades?

If you’ve never sharpened mower blades before, here’s a quick snapshot of the process:

  1. Firstly, disconnect the spark plug wire to ensure safety. 
  2. Then, use a socket wrench to remove the blade from the mower. 
  3. Secure the blade in a vise and use a metal file or grinder to sharpen the blade’s cutting edge. 
  4. Ensure that the blade is balanced and reattach it to the mower. 

It’s recommended to sharpen the blade at least once a year or more frequently if the mower is used often or on rough terrain. Regularly sharpening the mower blades can help ensure a healthy and lush lawn.

How do I maintain my lawn?

In addition to the tips already discussed, several other ways exist to maintain a healthy, green lawn and prevent it from turning yellow. 

How do I maintain my lawn
  • Be mindful of foot traffic and avoid compacting the soil in high-traffic areas. 
  • Consider adding stepping stones or a path to divert foot traffic and minimize damage to the grass. 
  • Consider the pH of the soil. Many types of grass prefer slightly acidic soil with a pH between 6.0 and 7.0. Test the soil every few years to ensure it is within this range, and adjust the pH with lime or sulfur as needed. Lime will help to raise the pH; sulfur will help to lower it.
  • Consider using organic fertilizers that release nutrients slowly and naturally, such as compost or worm castings. These fertilizers improve soil health and promote strong root growth, resulting in a healthier, more resilient lawn. 
  • Finally, consider using drought-resistant grass varieties, especially in areas prone to dry spells. These grasses require less water and can withstand heat and dry conditions. 

Following these tips and maintaining good lawn care practices can keep your lawn green and healthy all season long.

Frequently Asked Questions (FAQs)

Can grass come back from being yellow?

Yes, grass can come back from being yellow if the underlying issue causing the yellowing is resolved. Proper watering, fertilization, and care can encourage regrowth and healthy green grass. However, it may be more difficult to revive if the yellowing is due to disease or other serious issues.

How long does grass take to go from yellow to green?

The time it takes for grass to turn green from yellow depends on several factors, such as the cause, the type of grass, and the extent of the damage. In some cases, grass may turn green within a few days, while in others, it may take weeks or even months to fully recover.

Is yellow grass dead or dormant?

Yellow grass is not necessarily dead, but it can indicate a dormant or highly stressed lawn. Dormancy occurs when the grass goes into survival mode during drought or extreme temperatures. However, if the grass has been yellow for an extended period, it may not be able to recover and could eventually die.

Does yellow grass mean too much water?
