Bermuda Pasture Leaf Death After Fertilizing: Fertilizer Burn or Drought?

North of Houston. Fertilized pastures 3 weeks ago. Grass blades died, stems standing. Some rain, not much. Two cuts during drought. Ground usually wet, not this year.

Classic Fertilizer Burn Scenario

• Applied fertilizer to moisture-stressed grass.
• No rain/irrigation to move nutrients into soil.
• Mowed twice (removing leaf area needed for recovery).
• Salt index of fertilizer draws water from plant cells → desiccation.

Immediate Recovery Steps

1. Water deeply: Wet top 6 inches of soil.
2. Continue: Keep watering until grass leafs out and fills in.
3. Don't mow until active growth resumes.

Other Possible Causes

• Over-application (spreader calibration error).
• Weed-and-feed product (herbicide damage to stressed grass).
• Contaminated fertilizer batch (rare).

Prevention

• Never fertilize drought-stressed grass without irrigation guarantee.
• Use slow-release N (SCU, polymer-coated).
• Calibrate spreader annually.
• Water in fertilizer within 24 hours.
