Fertilizing New St. Augustine Sod: Skip the Miracle-Gro, Test Your Soil

The Sod Company's Advice

"Use only Miracle-Gro Lawn Fertilizer." Well-intentioned, but misguided.

Why Synthetic Liquid Fertilizer Falls Short

• Fast green-up, but color fades in hours—most nitrogen volatilizes or leaches.
• In heat, burns foliage.
• Feeds grass, not soil biology. Creates dependency.

Better Alternatives

• Ringer or Milorganite: slow-release, organic-based, longer-lasting.
• Soil test first. Only a test reveals what your grass actually needs. Contact your local extension (provide zip code for exact office).

St. Augustine Specifics

Warm-season grass. Fertilize during active growth (late spring–early fall). Avoid high nitrogen in late fall. Build soil health with compost topdressing and organic fertilizers for sustained vigor.
