Pink snow mold typically develops under which conditions?

Pink snow mold typically develops under which conditions?

• A. Cool (below 60°F), wet weather in fall, winter, or spring
• B. Hot, dry weather in summer
• C. Dry, windy conditions in autumn
• D. Frozen soil with no moisture

Answer: (A)

Pink snow mold requires a specific mix of cool temperatures and moisture. When turf stays cool (roughly below 60°F) and the leaf or soil surface remains wet for extended periods—such as during fall, winter, or early spring, often under snow cover—the fungal pathogen can germinate and infect the grass. That combination of cool weather with persistent moisture is what allows pink snow mold to develop, not when it’s hot and dry, dry and windy, or frozen with no moisture.
