How to Prevent Lawn Burn from Fertilizers in Zone 7 This July

by

Maintaining a lush, green lawn during the hot summer months can be challenging, especially in Zone 7 where temperatures tend to rise in July. One common issue faced by homeowners is lawn burn caused by improper fertilizer application. This article provides essential tips to prevent lawn burn and keep your grass healthy throughout July.

Understanding Lawn Burn and Its Causes

Lawn burn occurs when fertilizers, especially nitrogen-based ones, are applied excessively or at the wrong time, leading to dehydration and damage to grass blades. Hot weather, combined with fertilizer, can intensify this effect, causing patches of brown, scorched grass.

Tips to Prevent Lawn Burn in July

  • Test Your Soil: Conduct a soil test to determine nutrient levels and pH. Proper knowledge helps in applying the correct amount of fertilizer.
  • Use Appropriate Fertilizer: Choose a slow-release or low-nitrogen fertilizer designed for summer use. Avoid high-nitrogen formulas during peak heat.
  • Apply Fertilizer Carefully: Follow the manufacturer’s instructions precisely. Use a spreader for even distribution and avoid overlapping.
  • Timing Is Key: Fertilize early in the morning or late in the evening when temperatures are cooler. Avoid fertilizing during the hottest part of the day.
  • Water After Fertilizing: Lightly water your lawn after applying fertilizer to help nutrients penetrate the soil and prevent burning.
  • Adjust Mowing Practices: Keep your grass at a taller height (around 3 inches). Taller grass shades the soil, reducing heat stress and improving drought resistance.
  • Maintain Proper Irrigation: Water deeply and infrequently to promote deep root growth. Avoid frequent shallow watering that can stress the grass.

Additional Tips for a Healthy Lawn

Besides fertilizing correctly, other practices can help your lawn withstand the summer heat:

  • Regular Aeration: Aerate your lawn to improve soil drainage and root growth.
  • Proper Overseeding: Fill in bare patches to maintain a dense turf that resists weeds and pests.
  • Weed Control: Keep weeds at bay, as they compete with grass for nutrients and water.
  • Monitor for Pests: Watch for signs of pests or disease that can weaken your lawn.

Conclusion

Preventing lawn burn in Zone 7 during July requires careful fertilization, proper watering, and good lawn care practices. By following these tips, you can enjoy a healthy, vibrant lawn all summer long without the damage caused by fertilizer burn.
