Torpedo Grass in St. Augustine & Endless Seed Heads: Organic Rescue Plan

Post-Katrina New Orleans lawn: new topsoil, sod, now torpedo grass invasion. St. Augustine produces non-stop seed stalks. Asks if nutrient deficient.

Torpedo Grass: Tough but Manageable

Panicum repens—rhizomatous, aggressive. "Move" is hyperbole. Persistent organic management works.

Seed Stalks = Stress Signal

St. Augustine rarely seeds profusely. Constant seeding indicates:

• Nutrient deficiency (especially nitrogen).
• pH imbalance.
• Compacted soil.
• Improper mowing/watering.

Complete Organic Program (10+ Years Proven)

1. STOP all chemicals. They kill microbes that build soil.
2. Sugar: 4–5 lbs/1,000 sq ft, broadcast, water in. Feeds microbes. Spring & fall. No burn risk.
3. Deep watering: 6+ inches, weekly (soaker hoses). St. Augustine folds blades when thirsty.
4. Mow high (3–4"), sharp blade.
5. Horticultural cornmeal: 10 lbs/1,000 sq ft for fungus prevention.
6. Corn gluten meal: Spring pre-emergent + slow N.
7. Alfalfa meal & lava sand: Optional nutrient boost.
8. Baking soda spray: 2 tbsp/gal for foliar fungus.
