Organic Lawn Renovation: Removing Cottonwood Roots, Fixing Hardpan, and Building Soil

Site-Specific Fixes

• Cottonwood root: Dig out, backfill with good soil.
• Hardpan areas: Mix 3 parts cedar bark mulch + 1 part clay soil. Fill excavated areas. Cedar repels insects, improves structure.

Grass Selection

Ryegrass is a cool-season "weed" in hot climates (dies in summer). For North Texas, stick with warm-season grasses (Bermuda, St. Augustine, Zoysia) or tall fescue in shade. Overseed with rye only for winter color if desired.

Organic Foundation Program

• Sugar (4 lbs/1,000 sq ft, spring/fall): Feeds microbes that enrich soil continuously.
• Deep watering (6+ inches): Weekly, encourages deep roots, prevents thatch.
• Mow high (3–5 inches), leave clippings.
• Baking soda spray (¼ cup/gal) at first cool-season growth for fungus prevention.

Advanced Amendments (New This Year)

• Lava sand & alfalfa meal: Light sprinkle, water in. Nutrient-dense.
• Alfalfa tea: 1 cup meal in 5 gal water, steep overnight. Foliar feed for flowers.
• Corn gluten meal: 15–20 lbs/1,000 sq ft early spring (Feb 15–Mar 15) and fall (Sep 15–Oct 15). Weed prevention, nitrogen, fungicide.

Ecosystem Benefits

Toads, lizards, snakes, birds, beneficial nematodes, and roaches control pests. Earthworms aerate. Weeds vanish in rich soil. After 8+ years: near-zero maintenance, thick green lawn, no chemicals.

Ants? They're Food.

Black ants attract beneficial predators. Cedar mulch may deter them. Organic program brings balance.
