Treating Brown Spots on Bermuda Grass in North Texas: Organic Solutions and Local Resources

Diagnosing the Problem

A homeowner in the Dallas area reports irregular brown patches on a Bermuda lawn—not classic round spots—despite record rainfall. The lawn receives plenty of water, so the issue isn’t drought. The symptoms point to a fungal disease, likely brown patch, which thrives in wet, cloudy conditions.

Organic Treatment: Horticultural Corn Meal

Apply 10 pounds of horticultural corn meal per 1,000 sq. ft. No need to water it in; rain will activate it. This organic amendment feeds beneficial soil microbes that suppress fungal pathogens.

Long-Term Strategy: An Organic Lawn Program

After a few years on a full organic regimen, the soil becomes biologically balanced and fungus problems largely disappear. The author, Charlotte, shares her experience in Irving: since switching to organics, she enjoys a thick, weed-free lawn with minimal inputs—about 2–4 hours per week and a fraction of the previous cost.
