Avoiding Lawn Burn: Best Practices When Mowing

by

Maintaining a lush, healthy lawn requires proper mowing techniques. One common issue homeowners face is lawn burn, which results from improper mowing practices. Understanding how to mow correctly can prevent damage and promote a vibrant, green yard.

Understanding Lawn Burn

Lawn burn appears as brown or scorched patches on your grass. It often occurs when the grass is cut too short or when mowing is done under stressful conditions such as extreme heat or drought. The damage can weaken the grass, making it more susceptible to pests and diseases.

Best Practices for Mowing to Avoid Lawn Burn

  • Set the Correct Mowing Height: Adjust your mower to leave the grass at an optimal height, usually between 2.5 to 3.5 inches for most lawns. Taller grass shades the soil, retains moisture, and protects roots from heat stress.
  • Follow the One-Third Rule: Never cut more than one-third of the grass height at a time. Removing too much foliage at once stresses the grass and can cause burn.
  • Keep Mower Blades Sharp: Dull blades tear grass rather than cut it cleanly, leading to ragged edges that dry out and turn brown.
  • Adjust Mowing Frequency: Mow regularly to maintain the proper height, especially during peak growing seasons.
  • Avoid Mowing During Extreme Conditions: Refrain from mowing during the hottest parts of the day or during drought conditions to reduce stress on the grass.
  • Maintain Proper Mower Settings: Use appropriate settings for your grass type and season to ensure healthy mowing practices.

Additional Tips for Lawn Health

Besides proper mowing, other practices contribute to a healthy lawn and prevent burn:

  • Water Deeply and Infrequently: Proper watering encourages deep root growth and drought resistance.
  • Fertilize Appropriately: Use the right type and amount of fertilizer for your grass type and season.
  • Weed Control: Manage weeds to reduce competition for nutrients and water.
  • Aerate and Overseed: Improve soil health and fill in bare patches for a denser, more resilient lawn.

Conclusion

Proper mowing practices are essential to prevent lawn burn and maintain a vibrant, healthy yard. By setting the correct mower height, following the one-third rule, keeping blades sharp, and mowing under suitable conditions, homeowners can enjoy a lush green lawn throughout the season.
