Lawn fungus vs drought stress

Drought stress often shows as wilt, folded or dull leaves, footprints that stay visible, and dry soil in the root zone. It may appear first on slopes, compacted areas, curb strips, or irrigation gaps. UMN recommends mowing at 3 inches or higher because taller turf shades soil and supports drought tolerance.

Brown patch is favored by high humidity, warm nights, wet leaves, and lush growth. Dollar spot can show tan lesions with reddish-brown borders on leaf blades. Disease pressure is usually tied to weather, moisture duration, susceptible turf, and nitrogen management.

• Probe soil moisture in brown and green areas.
• Inspect leaves closely, not just the patch from across the yard.
• Review recent nitrogen, irrigation, and weather.
• Photograph the same spot every 2 to 3 days.

Use label directions and rotate modes of action when repeat applications are needed. You can compare fungicide options on the Price Board, but diagnosis comes first.
