New Sod Turns Brown: Why It Happens and What To Do About It

New sod is a great way to give your lawn an instant facelift. However, it can be frustrating to see it turn brown shortly after installation, leaving you wondering if you made a mistake in choosing this option. The good news is that this is a common problem, and there are several reasons why new sod turns brown. In this article, we will discuss the possible causes of this issue and provide tips on what you can do to prevent or correct it.

Reasons Why New Sod Turns Brown

1. Lack of Water

One of the most common reasons why new sod turns brown is due to a lack of water. Sod needs to be watered regularly so that it can establish its roots. Without adequate moisture, the sod will dry out and turn brown. It's important to follow the watering instructions provided by the supplier or installer. Typically, new sod requires daily watering for the first few weeks after installation.

2. Overwatering

While a lack of water can cause new sod to turn brown, overwatering can also be a problem. If the soil is constantly saturated, it can lead to root rot and other fungal diseases. This can cause the sod to turn brown, wilt, and die. Make sure to water your new sod deeply but infrequently, allowing the soil to dry out slightly between waterings.

3. Improper Soil Preparation

Another reason why new sod turns brown is due to improper soil preparation. Before installing sod, the soil should be properly graded and amended with organic matter. If the soil is too compacted or lacks nutrients, the sod may not be able to establish its roots properly. This can result in the sod turning brown and dying.

4. Poor Drainage

If the soil has poor drainage, it can also lead to new sod turning brown. If water is not able to drain away from the roots, it can cause them to rot and die. This can result in the sod turning brown and becoming patchy.

5. Inadequate Sunlight

New sod requires sunlight to photosynthesize and produce energy. If the sod is installed in a shady area, it may not receive enough sunlight to thrive. This can cause the sod to turn brown and become thin.

6. Soil pH

Sod prefers soil with a pH between 6 and 7. If the soil is too acidic or alkaline, it can lead to nutrient deficiencies, making it difficult for the sod to establish its roots. This can cause the sod to turn brown and die.

7. Improper Installation

If the sod is not installed properly, it can lead to air pockets between the sod and the soil. This can cause the sod to dry out and turn brown. It's important to make sure that the sod is installed tightly against the soil without any gaps.

8. Pests and Diseases

Pests and diseases can also cause new sod to turn brown. Common pests include grubs, chinch bugs, and armyworms. These insects feed on the roots of the sod, causing it to turn brown and die. Fungal diseases can also cause the sod to turn brown and become patchy.

9. Chemical Damage

Chemical damage can occur if herbicides or pesticides are applied improperly. If these chemicals come into contact with the sod, it can cause it to turn brown and die. It's important to follow the instructions provided by the manufacturer when applying any chemical treatments.

10. Weather Conditions

Extreme weather conditions can also cause new sod to turn brown. Hot and dry weather can cause the sod to dry out, while cold and wet weather can lead to root rot and other fungal diseases.

What To Do About New Sod Turning Brown

1. Watering

If your new sod is turning brown due to a lack of water, make sure to water it deeply and regularly. Follow the watering instructions provided by the supplier or installer. Typically, new sod requires daily watering for the first few weeks after installation. After that, you can gradually reduce the frequency of watering.

2. Soil Preparation

To prevent new sod from turning brown due to improper soil preparation, make sure to grade and amend the soil before installation. Use organic matter such as compost to improve soil structure and add nutrients.

3. Drainage

If poor drainage is the cause of your new sod turning brown, consider installing a drainage system or adding sand to improve soil drainage.

4. Sunlight

If your new sod is installed in a shady area, consider pruning trees or shrubs to allow more sunlight to reach the sod. Alternatively, you can choose a shade-tolerant variety of sod.

5. pH Adjustment

If the soil pH is too acidic or alkaline, consider adding lime or sulfur to adjust the pH to the optimal range for sod.

6. Proper Installation

To prevent air pockets between the sod and the soil, make sure to install the sod tightly against the soil without any gaps. Consider rolling the sod after installation to ensure good contact with the soil.

7. Pest and Disease Control

To prevent pests and diseases from damaging your new sod, consider using natural pest control methods or consult with a professional if necessary.

8. Chemical Treatment

If chemical damage is the cause of your new sod turning brown, stop using the chemical treatment immediately and follow the instructions provided by the manufacturer to minimize damage.

9. Weather Protection

To protect your new sod from extreme weather conditions, consider using shade cloth or frost blankets to regulate temperature and moisture levels.

Q4. How can you tell if new sod is getting enough water?

A. A good way to tell if new sod is getting enough water is to check the soil moisture level. Stick a screwdriver or other sharp object into the soil. If it goes in easily, the soil is moist enough. If it's difficult to penetrate, the soil may be too dry.

Q5. Can new sod be installed in the winter?

A. Yes, new sod can be installed in the winter, but it may take longer to establish its roots due to colder temperatures and shorter days. Consider using a frost blanket to protect the sod from freezing temperatures.
