Why is my zoysia grass dying?
Zoysia grass is a popular choice for lawns due to its ability to withstand heat, drought, and heavy foot traffic. However, even with its resilient nature, zoysia grass can sometimes encounter issues that lead to it dying. Understanding the potential reasons behind this can help you identify and address any problems to revive your lawn. In this article, we will explore the common causes of zoysia grass dying and provide solutions to help you restore its health.
Insufficient Watering
One of the main culprits behind dying zoysia grass is insufficient watering. This grass variety requires regular watering, especially during the hot summer months. Without adequate moisture, the grass can become weak and prone to diseases and pests. Here are some factors to consider when watering your zoysia grass:
- Frequency: Zoysia grass should be watered deeply but infrequently. Aim for watering 1-1.5 inches per week, either through rainfall or irrigation.
- Timing: Water early in the morning to allow the grass blades to dry before evening, which helps prevent the growth of fungal diseases.
- Irrigation method: Use slow and deep watering techniques, such as drip irrigation or soaker hoses, to ensure the water penetrates deep into the root zone.
- Avoid overwatering: While zoysia grass requires regular watering, overwatering can lead to shallow root growth and increased susceptibility to diseases.
Poor Soil Conditions
Another factor that can contribute to zoysia grass dying is poor soil conditions. Zoysia grass thrives in well-drained soil with a slightly acidic to neutral pH level. Here are some soil-related issues to consider:
- Compaction: Compacted soil prevents water and nutrients from reaching the roots. Aerating the lawn can help alleviate compaction and improve soil drainage.
- Poor drainage: Excessive water accumulation due to poor drainage can suffocate the grass roots. If you notice standing water after rainfall, consider improving the drainage system in your lawn.
- Nutrient deficiency: Zoysia grass requires essential nutrients for healthy growth. Conduct a soil test to identify any nutrient deficiencies and apply appropriate fertilizers to correct them.
- Soil acidity: Zoysia grass prefers a soil pH level between 6.0 and 7.0. If your soil is too acidic or alkaline, consider adding lime or sulfur to adjust the pH accordingly.
Invasive Weeds
Weeds can compete with zoysia grass for essential nutrients, sunlight, and water, which can lead to its decline. Identifying and effectively controlling weeds in your lawn is crucial for maintaining the health of your zoysia grass. Here are some common weeds that can invade zoysia lawns:
- Crabgrass: Prevent crabgrass by applying pre-emergent herbicides in early spring. For existing crabgrass, spot treat with post-emergent herbicides.
- Dandelions: Hand-pulling or using herbicides specifically designed for broadleaf weeds can help control dandelions in your zoysia lawn.
- Clover: Apply herbicides targeting clover in early spring or fall to effectively control its growth in your lawn.
- Other weeds: Regular lawn maintenance practices such as mowing at the correct height and maintaining a dense, healthy turf can help suppress the growth of various weeds.
Pests and Diseases
Zoysia grass is generally resistant to pests and diseases, but it can still be affected under certain conditions. Here are some pests and diseases that can cause zoysia grass to die:
- Chinch bugs: These small insects feed on grass blades, causing them to turn yellow and eventually die. Apply appropriate insecticides to control chinch bug infestations.
- Grubs: Grubs are beetle larvae that feed on grass roots, leading to weakened and dying grass. Treat your lawn with insecticides targeted at grubs if they become a problem.
- Fungal diseases: Conditions like excessive moisture, poor air circulation, and the presence of thatch can contribute to fungal diseases, such as brown patch and dollar spot. Fungicides and proper cultural practices can help manage these diseases.
In conclusion, several factors can contribute to the dying of zoysia grass, including insufficient watering, poor soil conditions, invasive weeds, and pests and diseases. By addressing these issues promptly and using appropriate solutions, you can revive your zoysia lawn and ensure its long-term health. Remember to provide adequate water, improve soil conditions, control weeds, and monitor for pests and diseases. With proper care, your zoysia grass will thrive and provide you with a beautiful and lush lawn.

Frequently Asked Questions
Why is my zoysia grass dying?
Here are the possible reasons why your zoysia grass might be dying and what you can do to address the issue:
1. Is your zoysia grass getting enough sunlight?
Zoysia grass requires at least 4-6 hours of direct sunlight daily to thrive. If your grass is not receiving sufficient sunlight, it may become weak and eventually die. Consider trimming surrounding trees or plants to allow more sunlight to reach the grass.
2. Could improper watering be the cause?
Zoysia grass needs regular but infrequent watering. Overwatering can lead to shallow root growth, disease, and fungus problems, while underwatering can cause the grass to dry out and die. Ensure that you are watering your zoysia grass deeply and infrequently, allowing the soil to dry out between watering sessions.
3. Are you mowing your zoysia grass correctly?
Zoysia grass should be mowed to a height of 1-2 inches. Mowing too short can weaken the grass and make it more susceptible to stress and diseases. Additionally, avoid cutting more than one-third of the grass blade length at a time to prevent shock. Follow proper mowing practices to promote healthy growth and avoid damaging your zoysia grass.
4. Are you providing adequate nutrients?
Zoysia grass requires regular fertilization to maintain its health and vigor. Lack of proper nutrients can result in weak growth and make the grass susceptible to diseases. Ensure that you are applying a balanced fertilizer specifically formulated for zoysia grass, following the recommended application rates and schedule.
5. Could pests or diseases be affecting your zoysia grass?
Pests and diseases, such as grub worms, brown patch, or dollar spot, can cause significant damage to zoysia grass. Monitor your lawn for signs of pests or diseases, such as discoloration, thinning, or patches of dead grass. If detected, take appropriate measures to control the pests or diseases and prevent further damage.
6. Could compaction or poor soil quality be the issue?
Zoysia grass prefers well-drained soil to thrive. Compacted soil or poor soil quality can impede root growth and lead to the death of the grass. Consider aerating the soil to alleviate compaction and improve drainage. Conduct a soil test to determine if any amendments, such as lime or organic matter, are necessary to enhance the soil quality for optimal zoysia grass growth.
