Reseeding vs. Resodding St. Augustine in Florida

Pinellas County, FL: Vacant house, dead St. Augustine. Asks if grass seed can replace sod realistically.

Florida Warm-Season Reality

  • St. Augustine: NO commercial seed (sterile hybrid). Must sod/sprig/plug
  • Bermuda: Seed available (common + some hybrids)
  • Zoysia: Limited seed, mostly vegetative
  • Bahiagrass: Excellent seed option, low maintenance
  • Centipede: Seed available

Seed Options for Florida

Diagnose First

Why did St. Augustine die?

  • Chinch bugs (primary pest)
  • Take-all root rot (fungus)
  • Cold damage (St. Aug tender)
  • Neglect/drought
  • Soil issues (pH, nematodes)

Soil test ($20) before investing.

Strategy

  1. Soil test → amend
  2. Glyphosate kill dead areas
  3. Choose grass by priority:
    • Best look: Hybrid Bermuda sod
    • Best value: Common Bermuda seed
    • Lowest maintenance: Bahiagrass seed
    • Shade areas: St. Augustine plugs/sod
  4. Prep: Till, grade, organic matter
  5. Establish: Water 2-3x daily light until rooted

Seed works for Bermuda/Bahia/Centipede. St. Augustine requires vegetative planting. Match grass to site conditions and maintenance commitment.
