Have you ever noticed a patchy disease on your lawn? Have you wondered what this disease could be and how it is affecting your lawn? We’ve got answers, people! Snow mold is a cold-weather fungus primarily affecting cool-season grasses. However, it is typically not a threat and rarely leads to serious damage on home lawns.
When Will I Be Able to Spot Snow Mold?
Why Should I Watch Out for It?
What Are the Symptoms?
Pink Snow Mold:
- Small spots 1-3 inches in diameter to begin with
- Centers of pink snow mold become reddish-brown and then tan
- Patches expand to 12 inches and have a pink margin
Gray Snow Mold:
- Patches of gray snow mold take on a scalded appearance and then turn a gray-white.
- Gray snow mold patches may expand to 2 feet, with a gray-white halo.
Pro Tip: In many cases, the diseases look very similar and can only be positively differentiated by microscopic inspection. Turf grass blades are generally matted down within the patches. Small brown to black fungal structures may be embedded in the plant tissue.
What Can Be Done to Prevent It?
How Do I Treat It?
If you don't apply a preventative fungicide in fall and you find snow mold damage in your lawn in early spring, the bet thing to do is gently rake the affected areas to aid in recovery. Raking removes matted grass, improves air circulation, and stimulates new grass growth.
