Why Is My Lawn Brown? Diagnosing the Cause Before Treatment

A brown lawn can stem from many causes, and effective treatment depends on accurate diagnosis. Before applying any products, consider these key factors:

Critical Questions to Answer

• Location: Northern (cool-season) or Southern (warm-season) climate?
• Grass type: Kentucky bluegrass, fescue, Bermuda, zoysia, centipede, etc.?
• Timing: When did it turn brown—suddenly or gradually?
• Recent history: Drought, over-fertilization, herbicide use, insect activity?

Common Causes by Region

Cool-season lawns (North): Summer heat dormancy, drought stress, disease (brown patch, dollar spot), grub damage, or chemical burn.

Warm-season lawns (South): Winter dormancy (normal), spring green-up delay, cold injury, or fungal disease.

Next Steps

Without specifics, it's impossible to recommend a fix. If the lawn is dormant, it will recover naturally. If dead, renovation (aeration, overseeding, or sodding) may be needed—timing depends on grass type and region. Submit details for a targeted plan.
