How to Avoid Lawn Burn in Hot May Sun

by

As temperatures rise in May, many homeowners notice their lawns developing brown patches. This phenomenon, known as lawn burn, occurs when excessive heat and sunlight damage the grass. Understanding how to prevent lawn burn is essential for maintaining a lush, green yard during hot weather.

What Causes Lawn Burn?

Lawn burn is primarily caused by prolonged exposure to intense sunlight combined with dry conditions. When grass receives more sunlight than it can handle, it loses moisture rapidly, leading to dehydration and browning. Factors that contribute include:

  • High daytime temperatures
  • Extended periods of direct sunlight
  • Insufficient watering
  • Poor soil drainage
  • Over-fertilization

Tips to Prevent Lawn Burn

Implementing proper lawn care practices can significantly reduce the risk of burn. Here are effective strategies:

  • Water Deeply and Infrequently: Water your lawn early in the morning to ensure deep soil penetration, which helps grass withstand heat.
  • Adjust Mowing Height: Keep your grass slightly taller during hot months, as taller grass shades the soil and reduces evaporation.
  • Limit Sun Exposure: Use shade structures or plant shade trees to protect sensitive areas from direct sunlight.
  • Avoid Fertilizer Overuse: Excess fertilizer can stress the grass, making it more susceptible to burn.
  • Maintain Proper Soil Health: Aerate and amend soil to improve drainage and root health.

Additional Lawn Care Tips

Beyond watering and mowing, consider these practices:

  • Use Mulch or Organic Cover: Mulching around the grass can help retain moisture and keep roots cool.
  • Choose Resilient Grass Varieties: Select grass types suited to your climate that are more resistant to heat stress.
  • Monitor Weather Conditions: Adjust watering and maintenance based on forecasted heatwaves.
  • Reduce Traffic: Limit foot and equipment traffic during hot days to prevent additional stress on the grass.

Conclusion

Preventing lawn burn in May’s hot sun requires proactive care, including proper watering, mowing, and soil management. By following these tips, you can enjoy a healthy, vibrant lawn throughout the summer months and beyond.
