New Sod Burned by Overlapped Fertilizer: Recovery Steps for Clay Soil

Grass Type Determines Urgency

• Warm-season (Bermuda, St. Augustine, zoysia): Summer fertilization appropriate. Flush salts, continue monthly feeding.
• Cool-season (bluegrass, fescue, rye): Summer fertilization harmful. Flush salts, stop fertilizing until fall.

Immediate Remediation (Both Types)

1. Heavy irrigation: 1–2 inches daily for 3–5 days to move salts below root zone (clay at 4–6 inches slows leaching—water longer).
2. No mowing until green returns.
3. No further fertilizer for 60 days.

Watering Transition

If sod rooted (tug test), shift from every-other-day to 2×/week, 1 hour each (deep, infrequent). If not rooted, keep frequent light watering until rooted.

Patch Repair if Needed

Cut out dead spots, replace with fresh sod pieces, water daily 2 weeks.

Future Prevention

• Measure lawn area, calculate exact product needed (3 lbs/1,000 sq ft for 28-4-14 types).
• Set spreader low, make two perpendicular passes.
• Calibrate with a test weigh.
