Use 1-2 pounds of Bermuda grass seed per acre for optimal coverage.

For new lawns, 1-1.5 lbs/acre of hulled Bermuda seed is standard, while 2 lbs/acre ensures thicker coverage in poor soil. Unhulled seed requires 2-3 lbs/acre due to lower germination rates. Always check seed purity (typically 85-95%) and adjust rates accordingly.

Key Factors Affecting Seeding Rate

• Seed Type: Hulled (faster germination) vs. unhulled (cheaper but less efficient).
• Soil Conditions: Sandy or low-fertility soil may need +20% more seed.
• Purpose: Pastures (1 lb/acre) vs. lawns (1.5-2 lbs/acre) vs. sports fields (2-3 lbs/acre).
• Climate: Warmer regions (faster growth) may allow lower rates than cooler zones.

Bermuda Seed Rates by Use Case

Step-by-Step Calculation Guide

1. Check seed label: Confirm purity percentage (e.g., 90% pure = 10% inert matter).
2. Adjust for purity:
   • Desired rate: 1.5 lbs/acre
   • Purity: 85% → 1.5 lbs ÷ 0.85 = 1.76 lbs actual seed needed
3. Measure area: Convert square feet to acres (43,560 sq ft = 1 acre).
4. Divide for small plots: 1 lb covers ~43,560-87,120 sq ft (1-2 acres).
5. Calibrate spreader: Test on a 10×10 ft area to avoid over/under-applying.

Common Mistakes to Avoid

• Overseeding: Exceeding 3 lbs/acre causes competition, weak growth, and disease risk.
• Ignoring soil prep: Compacted or weedy soil reduces germination by up to 50%.
• Skipping soil tests: Low pH (<6.0) or poor nutrients stunt establishment.
• Wrong season: Seed in late spring/early summer when soil temps exceed 65°F.
• Uneven distribution: Use a broadcast spreader for consistency; hand-seeding often clusters.
