Organic Solutions for Fungus in Newly Seeded Lawns

Identifying Fungus in New Grass

Two weeks after seeding, Ellen noticed small patches of grass that had "fallen over"—a classic sign of fungal disease (often damping-off or brown patch). Early intervention prevents spread.

Baking Soda Spray: A Simple Organic Fungicide

Dissolve ¼ cup baking soda in 1 gallon of water. Spray affected areas until saturated. Repeat as new symptoms appear. Baking soda alters leaf surface pH, inhibiting fungal growth without harming grass.

Corn Gluten Meal: Weed Control and Fungus Suppression

Corn gluten meal (a byproduct of corn syrup production) acts as a natural pre-emergent weed suppressant and provides nitrogen. It also helps reduce fungal activity. Apply at 20 lbs per 1,000 sq ft in early spring and fall.

Cultural Practices to Prevent Recurrence

• Water deeply but infrequently (1 inch per week).
• Mow high (3 inches) once grass reaches 4 inches.
• Avoid evening watering to reduce leaf wetness.
• Ensure good air circulation by not over-seeding.

When to Expect Results

Treated areas typically recover in 7–14 days. New seedings are vulnerable; consistent organic care builds long-term disease resistance.
