Organic Dallas Grass (Dallisgrass) Control in Texas Lawns

Reader Challenge: Persistent Dallisgrass in Bermuda Lawn

A Dallas/Plano homeowner spent a year with ChemLawn but still has Dallisgrass. They want organic solutions compatible with watering restrictions.

My North Texas Organic Success Story

I live in Irving. Ten years ago I went fully organic. Result: thick, lush, weed-free lawn with zero harmful insects. Dallisgrass, crabgrass, Johnson grass, dandelions, clover, dollar weed—all gone within 2–3 years. The program works in any climate, any grass type.

The Core Program (Same as Always)

• Sugar: 4–5 lbs/1,000 sq ft spring & fall. Feeds microbes, builds weed-suppressive soil.
• Deep watering: 6-inch depth, once weekly (more in 100°F+). Soaker hoses, cycle soak method. St. Augustine folds blades when thirsty; Bermuda bows.
• No chemicals: They kill microbes, nematodes, beneficial insects, and wildlife.
• Wildlife allies: Lizards, toads, grass snakes eat all pests. Cockroaches aerate soil and eat harmful bugs—keep them out of the house with fresh rosemary.
• Fungus control: Baking soda spray (2 tbsp/gal) or agricultural corn meal (10 lbs/1,000 sq ft).
• Corn gluten meal: Organic pre-emergent + nitrogen.
• Alfalfa meal & lava sand: Nutrient boosters, great for blooms too.

Follow-Up: Fire Ants Organically

Orange oil is the key. Chop orange peels, scatter, or mix 2 oz orange oil + 1 oz molasses + 1 cup compost tea per gallon water. Spray mounds directly. Dried molasses works but sugar is cheaper, easier, and I prefer the results. Howard Garrett's DirtDoctor.com is an excellent resource.

Watering Restrictions? No Problem

Deep, infrequent watering trains roots to go deep, making lawns more drought-tolerant. Once-weekly soaking meets most restrictions and outperforms frequent shallow watering.

Bottom Line

Stop fighting weeds. Start feeding soil. The weeds vanish, the grass thrives, and you reclaim your weekends.
