As summer approaches, many homeowners are concerned about maintaining a lush, green lawn during the hot months. One common issue is lawn burn, which occurs when grass is damaged by excessive heat, sunlight, and dehydration. Understanding how to prevent lawn burn is essential for a healthy, vibrant yard throughout June and the rest of summer.
Understanding Lawn Burn
Lawn burn, also known as “grass scorch,” happens when grass blades are exposed to intense sunlight and high temperatures without adequate water. This results in browning, wilting, and sometimes permanent damage to the grass. Factors such as drought stress, over-fertilization, and improper mowing can exacerbate the problem.
Tips to Prevent Lawn Burn
1. Water Deeply and Infrequently
Ensure your lawn receives about 1 to 1.5 inches of water per week, including rainfall. Water deeply to encourage deep root growth, which helps grass withstand heat. Early morning watering is best to reduce evaporation and fungal issues.
2. Mow at the Right Height
Keep your grass at a height of 2.5 to 3 inches. Taller grass shades the soil, reduces water evaporation, and protects roots from direct sunlight. Avoid cutting more than one-third of the grass height at a time to prevent stress.
3. Use Proper Fertilization
Apply a balanced, slow-release fertilizer in early summer. Over-fertilizing can lead to rapid, weak growth that is more susceptible to burn. Follow manufacturer instructions for best results.
4. Aerate and Overseed
Aerating improves soil drainage and oxygen flow, while overseeding helps fill in bare or thin patches. Healthy, dense grass is more resistant to heat stress and burn.
Additional Tips for Summer Lawn Care
Besides watering, mowing, and fertilizing, consider these practices to protect your lawn during hot June days:
- Limit foot traffic during peak heat hours to reduce stress.
- Apply a layer of mulch or organic matter around the grass to retain soil moisture.
- Use shade structures or plant trees to provide relief from direct sunlight.
- Avoid chemical treatments that can dry out or weaken the grass.
Conclusion
Preventing lawn burn during June’s summer heat requires proactive care and attention. By watering properly, mowing at the right height, fertilizing appropriately, and implementing additional summer lawn practices, you can enjoy a healthy, green lawn all season long. Proper summer lawn maintenance not only enhances curb appeal but also promotes the long-term health of your grass.
