Sun vs. Shade Grass Failure: Fungus from Overwatering

Brown spots only in sunny areas—while shade grass thrives—indicate a sun-loving grass variety (likely Kentucky bluegrass or rye) getting fungused by daily watering. Shade grass (likely fescue) resists the same fungus.

Daily watering keeps leaf surfaces wet, incubating fungal spores. Stop fertilizing—excess nitrogen pushes tender, disease-prone growth. Overseed dead sunny areas with disease-resistant varieties.

Topdress with compost/humus/aged manure. Switch to deep, infrequent watering. No fungicides—they kill beneficial fungi that suppress pathogens.

Scotts "system" products often over-fertilize. Build soil health instead.
