Yellowing of New Fescue Grass – 4 Common Problems
New fescue grass turning yellow can be a frustrating experience for homeowners. Yellowing can be caused by a variety of factors, including overwatering, underwatering, disease and fungal infections, pests and insect infestation, fertilizer burn, and nutrient deficiency.
1. Overwatering and Underwatering
Overwatering and underwatering can both cause yellowing of fescue grass. Overwatering can lead to root rot, which can cause the grass to turn yellow and eventually die. On the other hand, underwatering can cause the grass to become stressed and turn yellow.
To avoid overwatering, it is important to ensure that the soil is well-draining and that the grass is not watered too frequently. To avoid underwatering, it is important to water the grass deeply and infrequently.
2. Disease and Fungal Infections
Disease and fungal infections can also cause fescue grass to turn yellow. Common fungal diseases that can cause yellowing include brown patch and dollar spot. These diseases can be prevented by ensuring that the grass is not overwatered and that it is properly fertilized.
3. Pests and Insect Infestation
Pests and insect infestation can also cause yellowing of fescue grass. Common pests that can cause yellowing include chinch bugs, grubs, and sod webworms. These pests can be prevented by ensuring that the grass is properly fertilized and that it is not overwatered.
4. Fertilizer Burn and Nutrient Deficiency
Fertilizer burn and nutrient deficiency can also cause fescue grass to turn yellow. Overfertilization can cause the grass to burn, while nutrient deficiency can cause the grass to become stressed and turn yellow. It is important to ensure that the grass is properly fertilized and that it receives the necessary nutrients to remain healthy.
Impact of Seasonal Changes
Summer Heat Stress
Fescue grass is a cool-season grass that prefers temperatures between 60°F and 75°F. When temperatures rise above 85°F, fescue grass can experience heat stress. Symptoms of heat stress include yellowing, browning, and wilting of the grass blades.
To prevent heat stress, it is recommended to water the grass deeply and less frequently, preferably in the early morning or late evening when temperatures are cooler. Additionally, mowing the grass at a higher height can help to shade the soil and reduce water loss.
Fall Dormancy and Frost
In the fall, fescue grass enters a period of dormancy as temperatures begin to cool. During this time, the grass may turn yellow or brown and appear dead. However, this is a natural process and the grass will green up again in the spring.
Frost can also cause fescue grass to turn yellow. Frost damage is often temporary and the grass will recover once temperatures rise above freezing.
Winter Yellowing
Fescue grass can turn yellow in the winter due to a lack of sunlight and cold temperatures. This is a common occurrence and does not necessarily indicate a problem with the grass.
However, if the grass remains yellow in the spring, it may be a sign of a nutrient deficiency or other issue. To prevent winter yellowing, it is recommended to fertilize the grass in the fall and to avoid excessive foot traffic on the grass during the winter months.
Effects of Shade and Sun Exposure
Fescue grass requires a moderate amount of sunlight to grow and thrive. If the grass is planted in an area with too much shade or too much sun, it can turn yellow and become unhealthy.
Shade can be a problem for fescue grass because it limits the amount of sun that the grass receives. Without enough sun, the grass cannot perform photosynthesis, which is the process that allows plants to convert sunlight into energy.
This lack of energy can cause the grass to turn yellow and become weak. Additionally, shade can create a moist environment that can lead to fungal growth, which can also cause the grass to turn yellow.
On the other hand, full sun can also be a problem for fescue grass. If the grass is exposed to too much sun, it can become dehydrated and stressed. This can cause the grass to turn yellow and become brittle. To prevent this, it is important to water the grass regularly and deeply, especially during periods of hot, dry weather.
In general, fescue grass prefers to be planted in areas that receive partial sun or filtered shade. This allows the grass to receive enough sunlight to perform photosynthesis while also protecting it from the harsh rays of the sun.
If the grass is planted in an area with too much shade or too much sun, it may require additional care and attention to remain healthy and green.
In summary, the amount of shade or sun exposure that fescue grass receives can have a significant impact on its health and appearance. Planting the grass in an area with the appropriate amount of sunlight, regular watering, and proper care can help prevent yellowing and keep the grass looking green and lush.
Preventing and Treating Yellowing Fescue Grass
Fescue grass can turn yellow for a variety of reasons, including poor soil conditions, lack of water, disease, and pests. Preventing and treating yellowing fescue grass requires a combination of proper watering practices, fertilizing and soil amendments, disease control, and professional lawn care.
1. Proper Watering Practices
One of the most common reasons for yellowing fescue grass is lack of water. Proper watering practices can help prevent yellowing and promote healthy growth. Fescue grass should be watered deeply and infrequently, rather than lightly and frequently. This allows the water to penetrate deep into the soil and encourages deep root growth.
It is important to water fescue grass early in the morning or in the evening, when temperatures are cooler and there is less evaporation. Watering during the hottest part of the day can lead to water loss and stress on the grass.
2. Fertilizing and Soil Amendments
Fertilizing and soil amendments can help prevent yellowing fescue grass by promoting healthy growth and providing essential nutrients. Starter fertilizers can be used when planting new fescue grass to encourage root growth and establishment.
Ironite can be used to add iron to the soil, which can help prevent yellowing and promote green growth. Manure can also be used as a natural fertilizer and soil amendment, providing essential nutrients to the soil.
3. Disease Control and Fungicide Use
Disease and fungal infections can cause yellowing and other issues with fescue grass. Proper disease control and fungicide use can help prevent and treat these issues. Fungicides should be used as directed and only when necessary.
4. Professional Lawn Care
Professional lawn care can help prevent and treat yellowing fescue grass by providing regular maintenance and care. Lawn care professionals can provide fertilization and weed control services, as well as disease and pest control. They can also provide advice on proper watering practices and other lawn care techniques.
Comparative Analysis of Fescue with Other Grass Types
Fescue grass is a popular choice for lawns due to its shade tolerance, low maintenance requirements, and ability to grow in a variety of soil types. However, it is not immune to problems such as turning yellow, which can be a cause for concern for homeowners.
Compared to other grass types, fescue has a finer texture and is less tolerant of heavy foot traffic. Bermuda grass, on the other hand, is a popular choice for sports fields and golf courses due to its ability to withstand heavy use. St. Augustine grass is another popular choice for lawns in warmer climates due to its heat tolerance.
