If your Bermuda grass is turning brown, don’t panic—it’s often a sign that your lawn needs some extra care or adjustments. The good news is that many issues causing browning are fixable with some simple interventions.
Bermuda grass can turn brown for several reasons, such as drought stress, overwatering, soil compaction, pests, or disease. Addressing these issues promptly can help your lawn recover its lush green color. In this article, we’ll explore the common causes behind browning Bermuda grass and how you can bring your lawn back to life quickly and effectively. Whether it’s adjusting your watering schedule or treating pests, understanding the root cause is the first step to a healthier, greener yard.
Why Is My Bermuda Grass Turning Brown?
Understanding Bermuda Grass Health
Bermuda grass is a popular turf choice because it’s hardy and adapts well to warm climates. However, it can turn brown unexpectedly, causing homeowners to worry. Recognizing the reasons behind this change can help you restore its vibrant green color quickly.
Common Causes of Browning Bermuda Grass
Browning often results from a combination of environmental stresses, pests, or improper care. Identifying the specific cause is essential for effective treatment. Some common reasons include drought stress, overwatering, nutrient deficiencies, pests, and disease.
Environmental Stressors and Their Impact
Drought and Lack of Water
Bermuda grass requires regular watering to stay lush and green. During hot, dry periods, the grass can turn brown due to water deficiency. When the soil moisture drops below the grass’s needs, it goes into dormancy, causing the brown appearance.
Overwatering and Poor Drainage
While drought causes browning, overwatering can have similar effects. Excess water can suffocate roots, prevent oxygen from reaching the soil, and encourage fungal growth. Compacted or poorly draining soil exacerbates this problem, leading to brown patches.
Extreme Temperatures and Sunlight
High temperatures and intense sunlight can stress Bermuda grass, especially if it’s not adapted to such conditions. Sunburn may occur, resulting in brown, scorched patches on the turf. Proper shading and watering can help mitigate these effects.
Nutrient Deficiencies and Soil Imbalance
Low Nitrogen Levels
Nitrogen is vital for healthy, green grass. A deficiency causes the grass to turn yellow or brown as it cannot produce enough chlorophyll. Regular fertilization with a balanced nutrient mix can prevent this issue.
Imbalanced Soil pH
Bermuda grass prefers a soil pH between 6.0 and 6.5. Soil that’s too acidic or alkaline can hinder nutrient absorption, leading to browning and poor growth. Soil testing and pH adjustment help maintain optimal conditions.
Pest Infestations and Disease
Pests Causing Damage
Chinch bugs, armyworms, and other pests feed on Bermuda grass, weakening the turf and causing it to turn brown. Signs include irregular patches and visible insects. Using appropriate pest control methods helps manage infestations.
Fungal and Other Diseases
Fungal infections like brown patch or dollar spot can cause large brown areas. These usually develop in humid conditions or when the grass is stressed. Prompt application of fungicides and reducing humidity can control spread.
Improper Mowing and Maintenance
Cutting Too Short
Mowing Bermuda grass too short exposes the roots to sunlight and heat, increasing stress and browning. Keep your mower blades at a height of 1 to 1.5 inches for optimal health.
Ignoring Lawn Aeration and Dethatching
Compacted soil prevents air, water, and nutrients from reaching grass roots. Regular aeration and dethatching improve soil health and promote even color and growth.
Seasonal Changes and Dormancy
Bermuda grass naturally goes dormant during colder months, turning brown temporarily. Understanding this cycle helps distinguish between natural dormancy and problems requiring intervention.
How to Prevent and Fix Browning Bermuda Grass
Proactive care can reduce the chances of brown patches. Regular watering, fertilizing, pest monitoring, and aeration keep Bermuda grass healthy. For existing browning, proper watering, feeding, and pest control are key steps to recovery.
Steps for Restoring Your Bermuda Grass
- Test your soil pH and nutrient levels to identify deficiencies.
- Adjust watering schedule based on weather conditions — deep, infrequent watering encourages strong roots.
- Apply a nitrogen-based fertilizer suitable for Bermuda grass.
- Regularly mow at the recommended height to prevent stress.
- Inspect for pests and treat with appropriate insecticides.
- Manage weeds, thatch, and pests to reduce competition for nutrients.
- Improve soil drainage if waterlogging occurs.
- Consider overseeding or patching bare areas for a uniform look.
Additional Tips for Maintaining Green Bermuda Grass
Good lawn care routines can keep your Bermuda grass vibrant year-round. Regularly monitor the turf for early signs of problems and take corrective action promptly. Use drought-resistant varieties if your climate has prolonged dry seasons.

Frequently Asked Questions
What watering practices can cause Bermuda grass to turn brown?
If you water your Bermuda grass infrequently or irregularly, it can lead to the grass drying out and turning brown. Overwatering can also cause problems by promoting shallow root growth and encouraging fungal diseases, which may result in browning patches. Maintaining a consistent watering schedule that provides deep, infrequent watering helps keep the grass healthy and green.
How does soil compaction impact the health of Bermuda grass?
Compacted soil prevents proper air and water movement to the grass roots, causing stress and browning. When soil becomes dense, roots struggle to access essential nutrients and moisture, leading to dry, brown areas. Aerating the soil regularly relieves compaction, allowing roots to grow freely and improving overall turf health.
Can pests or diseases cause my Bermuda grass to turn brown?
Yes, certain pests like grubs and armyworms feed on Bermuda grass roots and foliage, resulting in patches of browning or thinning turf. Fungal diseases such as brown patch or dollar spot also attack the grass, especially during humid conditions. Identifying and treating pests and diseases promptly helps stop browning and restores turf vitality.
How does temperature stress affect Bermuda grass color?
Extreme heat or cold can stress Bermuda grass, causing it to turn brown. High temperatures can cause dehydration and scorch the leaves, while cold temperatures can slow growth and damage the turf’s ability to recover. Providing appropriate watering during hot weather and protecting the grass during cold spells supports its resilience and color retention.
What role does fertilization play in maintaining green Bermuda grass?
Insufficient or improper fertilization can lead to nutrient deficiencies, making Bermuda grass more prone to browning. Regularly applying a balanced fertilizer that supplies nitrogen, potassium, and other essential nutrients encourages vigorous growth and a lush, green appearance. Careful fertilization must be tailored to the season and lawn needs to avoid overfeeding and related issues.
Final Thoughts
Bermuda grass turns brown due to several factors such as drought, overwatering, or poor soil quality. Hot weather can cause stress, making the grass lose its vibrant color. Pests and diseases also play a role in browning patches.
Proper watering and fertilization help maintain healthy growth. Addressing pests early prevents further damage. Regular inspections ensure the grass remains green and lush.
Why is my bermuda grass turning brown? The main reasons include environmental stress, improper care, and pests. Understanding these causes allows you to take effective action and keep your lawn vibrant and healthy.
