Understanding Brown Spots in Bermuda Grass After Mowing
Brown spots in Bermuda grass after mowing can be frustrating for homeowners and lawn care enthusiasts alike. These spots appear as patches of grass that turn brown or dead, disrupting the lush green appearance of your lawn. To keep your Bermuda grass healthy and vibrant, it’s important to understand why these brown patches occur and how to prevent them.
Common Causes of Brown Spots After Mowing
Inconsistent Mowing Practices
One of the main reasons for brown spots is uneven mowing. Cutting the grass too short can damage the plant, making it vulnerable to stress and disease. Conversely, mowing too high can cause thatch buildup, leading to poor air circulation. Maintaining proper mowing height is essential.
High Mowing Frequency
Mowing too frequently can stress Bermuda grass, especially if the mower blade is dull. It prevents the grass from recovering, resulting in brown patches. Ideally, mow once a week and only when the grass reaches a certain height.
Weather Conditions and Stress
Hot and dry weather can make Bermuda grass more susceptible to browning after mowing. Lack of water combined with intense sunlight causes dehydration, leading to brown spots. Proper watering is critical during these conditions.
Underlying Soil and Nutrient Issues
Nutrient Deficiencies
Brown spots may indicate deficiencies in essential nutrients like nitrogen. Without enough nitrogen, the grass cannot produce healthy green blades, resulting in browning after mowing. Regular fertilization helps maintain nutrient balance.
Improper Soil pH
Soil pH levels that are too acidic or alkaline can hinder nutrient absorption. Testing soil regularly and adjusting pH with amendments ensures optimal conditions for Bermuda grass growth.
Compacted Soil
Compacted soil restricts root development and water penetration, making grass more vulnerable to damage. Aerating the lawn improves soil structure and allows roots to access nutrients more effectively, reducing brown spots.
Watering and Irrigation Factors
Overwatering or Underwatering
Both overwatering and underwatering can cause brown patches. Excess water leads to root rot, while too little causes dehydration. Establishing a proper watering schedule helps keep Bermuda grass healthy and resilient.
Timing of Watering
Water early in the morning to allow excess moisture to evaporate during the day. This prevents fungal growth, which can exacerbate brown spots after mowing.
Fungal Diseases and Pest Infestations
Fungal Infections
Fungal diseases such as dollar spot or brown patch can cause brown spots that appear after mowing. These are often worsened by moisture and poor air circulation. Fungicides can control these issues.
Pest Damage
Insects like grubs or mole crickets can damage roots, creating brown patches. Regular inspection and appropriate pest control measures keep the lawn healthy and reduce damage.
Damage from Mower Equipment
Sharpness of Mower Blades
Dull blades tear grass instead of cutting it cleanly, leading to brown tips and patches. Regularly sharpen mower blades to ensure a smooth cut.
Adjusting Mowing Height
Setting the mower blade at the correct height, typically around 1.5 to 2.0 inches for Bermuda grass, minimizes stress and prevents brown spots.
Prevention and Lawn Care Tips
Proper Mowing Techniques
- Maintain consistent mowing height based on grass type and season
- Avoid cutting more than one-third of the grass height at once
- Always use sharp mower blades for clean cuts
Appropriate Fertilization Schedule
Feed Bermuda grass with a balanced fertilizer rich in nitrogen during the growing season. Follow label instructions for application rates and timing.
Optimal Watering Practices
- Water deeply and infrequently to encourage deep root growth
- Adjust watering based on weather conditions
- Avoid watering during the hottest part of the day to reduce evaporation
Soil Testing and Lawn Aeration
Test your soil at least once a year to check pH and nutrient levels. Aerate to improve soil structure and allow better water and nutrient absorption.
Treating Existing Brown Spots
Reseeding and Overseeding
For patches that are heavily damaged, reseeding can help restore lawn density. Use Bermuda grass seeds suitable for your region.
Applying Fertilizer or Soil Amendments
Use specialized fertilizers for damaged areas. Incorporate soil amendments to improve pH and nutrient levels if needed.
Fungicide and Pest Control
If fungal infection or pests are detected, apply appropriate fungicides or insecticides. Always follow product instructions carefully.

Consistent maintenance, attention to soil health, and appropriate watering and fertilizing will help keep your Bermuda grass lush and green all year round.
Why does my bermuda grass turn brown after mowing and the easy fix
Frequently Asked Questions
What are common causes of brown spots appearing after mowing Bermuda grass?
Brown spots after mowing Bermuda grass often result from injury to the grass blades or roots. Some common causes include mowing when the grass is wet, which can tear the blades and cause stress, or cutting the grass too short, which exposes the stems and weakens the plant. Additionally, using dull mower blades can tear the grass instead of cutting it cleanly, leading to damage and discoloration. Environmental stresses like drought or high temperatures can also make Bermuda grass more susceptible to developing brown patches after mowing.
How can I prevent brown spots from forming after mowing my Bermuda grass?
To prevent brown spots, ensure you mow at the proper height, typically around 1 to 2 inches, and avoid cutting more than one-third of the grass blade at a time. Keep mower blades sharp to make clean cuts, reducing stress on the grass. Mow when the grass is dry to prevent tearing and damage. Maintain consistent watering practices to keep the soil moist but not waterlogged, and apply appropriate fertilization to strengthen the grass. Regularly inspecting and maintaining your mower will also help minimize injury to the lawn.
What steps should I take if brown spots appear after mowing Bermuda grass?
If you notice brown spots after mowing, first identify the cause by checking grass height, mower blade sharpness, and recent weather conditions. Remove any clippings or debris that can hinder air circulation. Water the affected areas deeply to promote recovery, and avoid mowing until the grass greens up again to prevent further stress. Applying a balanced fertilizer can encourage healthy growth. If the spots persist, consider aerating the lawn to improve soil health and reduce compaction, or consult a lawn care professional for targeted treatment.
Can improper mowing height lead to brown patches in Bermuda grass?
Yes, mowing Bermuda grass too short can stress the turf and cause brown patches. Cutting below the recommended height reduces the grass’s ability to shade the soil, leading to increased moisture loss and vulnerability to damage from heat or drought. Proper mowing height helps the grass develop a strong root system and resist environmental stressors. Maintaining the correct height encourages healthy growth and minimizes the chances of brown spots appearing after mowing.
Is it necessary to change mowing practices during different seasons to prevent brown spots?
Adjusting mowing practices according to the season can help prevent brown spots. During the hot summer months, raise the mower height to provide shade for the roots and reduce stress. In cooler seasons, you can mow slightly lower but should still avoid cutting too short. Always monitor the grass’s condition and avoid mowing when it is wet or stressed. Seasonal adjustments, combined with proper watering and fertilization, support overall lawn health and help prevent brown patches from forming after mowing.
Final Thoughts
Brown spots in Bermuda grass after mowing can result from various factors such as drought, over-fertilization, or mower blade issues. Ensuring proper watering and using sharp blades helps prevent these spots. Regular lawn maintenance encourages healthy, green growth.
Addressing these causes minimizes brown spots and promotes a lush lawn. Remember, consistent care and awareness of grass needs are key. A healthy Bermuda grass lawn remains vibrant and resilient after mowing.
