Did You Know?
1. Stressed grass can turn yellow: Excessive foot traffic, heavy objects, or prolonged exposure to extreme heat can cause the grass to turn yellow. Giving your lawn some time to recover without any disturbances can help it regain its green color.
2. Yellow grass can be a sign of nutrient deficiency: Often, yellowing grass is a sign that it lacks essential nutrients such as nitrogen, iron, or magnesium. Applying the appropriate fertilizer or soil amendments, as recommended by a soil test, can help restore the grass’s green hue.
3. Overwatering can cause yellow grass: Contrary to popular belief, giving your lawn too much water can actually lead to yellowing. Overwatering can suffocate the roots, preventing them from absorbing vital oxygen, resulting in yellow or light green grass. It is important to water your lawn deeply but infrequently to maintain its health.
4. Certain dog urine can cause yellow grass: The nitrogen content in dog urine can burn grass, leaving yellow patches. Diluting the urine by watering the affected area immediately after your dog urinates can help prevent yellowing. Additionally, training your dog to use a designated spot in your yard can concentrate the urine in one area and minimize damage.
5. Lawn diseases can turn grass yellow: Various fungal and bacterial infections can cause yellow patches on your lawn. For instance, diseases like Pythium blight or yellow patch present as circular areas of yellowed grass. It is essential to identify the specific disease and treat it accordingly to restore the grass’s natural color.
Cutting Grass Too Short
One common mistake homeowners make when mowing their lawn is cutting the grass too short. This can cause the grass to turn yellow due to a lack of moisture. When grass blades are too short, they are unable to retain enough water, resulting in dehydration and discoloration. To prevent yellow or brown patches, it is important to increase the cutting height of the lawn mower.
By raising the cutting height, you allow the grass to maintain a healthier length, which helps retain moisture and promote greener growth. Cutting the grass too short also puts added stress on the plant, making it more susceptible to disease and other issues. Therefore, increasing the cutting height is a simple yet effective way to prevent yellowing and maintain a lush, green lawn.
- Avoid cutting the grass too short to retain moisture.
- Increase the cutting height of the lawn mower.
- Maintain a healthier length for the grass.
- Promote greener growth by allowing the grass to retain moisture.
“Increasing the cutting height is a simple yet effective way to prevent yellowing and maintain a lush, green lawn.”
Adjusting Lawn Mower Height
In addition to avoiding cutting the grass too short, maintaining an even lawn height is crucial to prevent scalping and yellowing. Uneven lawns are more prone to certain areas being cut too short, which can cause the grass to turn yellow or brown. To achieve a neater finish and avoid yellow patches, it is important to flatten the lawn or adjust the cutting height in certain areas.
Luckily, many lawnmowers, including those offered by Flymo, come with central height adjustment features.

Natural Variations In Grass Color
It is important to note that not all grasses have the same natural color. Some grasses are naturally greener than others, and this variation can affect how easily the grass turns yellow. For example, warm-season grasses tend to turn yellowish brown in cooler months. This change in color is a natural occurrence and does not necessarily indicate a problem with the grass’s health.
Similarly, during hot and dry summers, turfgrass may turn yellow and go dormant as a survival mechanism. This is the grass’s way of conserving energy and water during periods of stress. However, if the grass remains yellow even when conditions are favorable, it may be a sign of an underlying issue that needs attention.
Common Causes Of Yellowing Grass
- Lack of water: One common cause of yellowing grass is insufficient watering.
- Nutrient deficiency: Another possible reason for yellowing grass is a lack of essential nutrients, such as nitrogen, phosphorus, or potassium.
- Soil pH imbalance: An imbalanced soil pH can also lead to yellowing grass. It is important to maintain the proper pH level for healthy grass growth.
- Pest or disease infestation: Certain pests or diseases, like grubs or fungal infections, can cause grass to turn yellow. Identifying and treating the specific problem is necessary for effective restoration.
- Mowing practices: Improper mowing practices, such as cutting the grass too short or using dull blades, can stress the grass and cause it to yellow.
- Environmental factors: Harsh weather conditions, such as extreme heat or cold, can also contribute to yellowing grass. Providing appropriate protection or adjusting care practices can help mitigate these effects.
Remember to investigate the underlying cause of yellowing grass before deciding on the appropriate course of action to restore its health.
Insufficient Watering
Watering your lawn on an irregular schedule or not giving it enough water can cause yellowing. Grass needs a consistent and adequate water supply to thrive. Dry periods or watering inconsistencies can lead to dehydration and yellowing of the grass.
- Watering your lawn regularly and giving it enough water is essential for maintaining healthy grass.
- Inconsistent watering can cause dehydration, which results in yellowing of the grass.
Note: It is important to ensure that your lawn receives proper and regular watering to prevent yellowing.
Soil Compaction
Soil compaction can interfere with drainage and root growth, leading to yellowing. Compacted soil prevents water from penetrating deep into the ground, resulting in poor hydration for the grass. It also restricts root development, making it difficult for the grass to access essential nutrients.
- Soil compaction reduces drainage and root growth
- Water penetration is hindered by compacted soil
- Poor hydration can lead to yellowing of the grass
- Restricted root development affects nutrient uptake
“Soil compaction can have detrimental effects on both drainage and root growth. The compacted soil prevents adequate water penetration, leading to poor hydration for the grass. Moreover, it restricts the development of roots, thereby making it challenging for the grass to obtain essential nutrients.”
Lawn Nutrient Deficiency
A nutrient deficiency in the lawn can cause yellowing. Each nutrient has a specific function in the growth and development of plants, and their absence can lead to improper functioning and discoloration. Common nutrient deficiencies that cause yellowing include:
- Nitrogen
- Iron
- Potassium
A lack of nitrogen, iron, or potassium can result in yellowing of the lawn. It is important to address these deficiencies to promote healthy growth.
Iron Chlorosis
Iron deficiency, also known as iron chlorosis, can cause yellowing grass. Iron is a micronutrient that plays a crucial role in the production of chlorophyll, which is responsible for the green color in plants. Without sufficient iron, the grass cannot produce enough chlorophyll, leading to yellowing leaves.
5. Insects and Pests
Insects like chinch bugs and grubs can infest lawns and cause yellow patches. These pests feed on the grass, causing damage to the roots and inhibiting proper nutrient absorption. As a result, the affected areas may start to turn yellow and eventually die if left untreated.
6. Fungus and Diseases
Fungi, such as turfgrass rust, can cause yellow spots on leaves and gradually spread through wet conditions and foot traffic. Fungal infections weaken the grass, making it more prone to yellowing. Proper identification of the fungus is necessary in order to apply the appropriate treatment and prevent further damage.
7. Overfertilization
Overfertilization, especially with excess nitrogen, can cause yellowing in lawns. While nitrogen is essential for healthy grass growth, an excessive amount can result in burn spots and yellowing. Quick release fertilizers, which release nitrogen rapidly, are more likely to cause a buildup of nitrogen salts, affecting the grass’s health.
8. Watering After Fertilization
Watering the lawn immediately after fertilization can minimize the risk of root burn and prevent yellowing. Fertilizers contain salts that can potentially damage the grass if not promptly watered in. Watering after applying fertilizer helps to dilute and distribute the nutrients evenly, promoting healthy growth.
Benefits of watering the lawn after fertilization:
- Minimizes the risk of root burn
- Prevents yellowing of the grass
“Watering immediately after applying fertilizer helps to dilute and distribute the nutrients evenly, promoting healthy growth.”
9. Water Conservation Efforts
During drought conditions, efforts to conserve water can unintentionally lead to yellow lawns. When water is limited, grass may enter a dormant state to conserve resources, resulting in yellowing. While water conservation is important, it is essential to strike a balance and provide enough water to keep the grass alive and healthy.
10. Dog Urine
High levels of nitrogen in dog urine can cause burn spots and yellow patches in the lawn. While it may be difficult to control where your pet goes, rinsing the affected areas with water after urination can help dilute the urine and minimize the damage caused. Training your dog to use a designated area can also prevent widespread yellowing.
11. Excessive Heat and Sunlight
Excessively hot weather and full sun exposure can cause yellow areas in the lawn. This is often due to the grass being unable to retain enough moisture under extreme conditions. Watering more frequently and deeply can help combat the effects of heat and sunlight, allowing the grass to stay hydrated and maintain its vibrant green color.
12. Pests and Fungus
If none of the above factors seem to be the cause of yellowing grass, pests or fungus could be the culprits. Close examination of the grass and soil is necessary to identify any signs of pest infestations or fungal diseases. Once identified, appropriate measures can be taken to address the specific issue.
Yellow grass is a common problem that can be caused by various factors. By following the essential tips and solutions outlined above, you can effectively fix yellowing grass and achieve a vibrant, healthy lawn. Remember to adjust your cutting height, water consistently, address soil compaction, ensure proper nutrient levels, and take appropriate actions against pests and diseases. With careful attention and good lawn care practices, you can enjoy a lush green lawn all year round.
Frequently Asked Questions
Can grass come back from being yellow?
Yellow grass can certainly come back with the right care and attention. When grass turns yellow, it is often a sign of dormancy rather than death. This typically occurs due to a lack of water and incorrect mowing techniques during this time of year. By properly watering your lawn and adjusting your mowing practices, the grass can be revived and return to its lush, green state. However, it is important to note that if the grass turns white, it has died and will require complete removal and replacement. So, as long as the grass is yellow and not white, there is hope for its revival.
