Thickening St. Augustine & Bermuda Grass Organically in Texas

A Texas homeowner wants to thicken St. Augustine and Bermuda grass while eliminating southern weeds—without chemicals.

The Organic Transformation

After 10 years on a fully organic program, this gardener eliminated weeds, reduced workload by 90%, cut costs dramatically, and even improved asthma symptoms. The secret: feed soil microbes, not the grass directly.

Core Practices

• Sugar: 4–5 lbs per 1,000 sq ft, broadcast and watered in. Feeds beneficial microbes that enrich soil and suppress weeds.
• Deep watering: Soak to 6+ inches once weekly (more in extreme heat). Encourages deep roots, prevents thatch.
• Corn gluten meal: Organic pre-emergent weed suppressor and nitrogen source.
• Alfalfa meal & lava sand: Nutrient-rich amendments that boost soil life and plant vigor.
• Baking soda spray: 2 tbsp/gallon for fungal issues like black spot and powdery mildew.

Nature's Pest Control

Earthworms, roaches, lizards, toads, and snakes aerate soil and eat pests. No pesticides needed—the ecosystem balances itself.

Stop chemicals. Start feeding the soil. Weeds vanish, grass thickens, and the yard becomes alive.
