Snow Mold
Typhula and Fusarium Blight
Winter snow cover can be hard on our lawns, leaving unexpected damage like snow mold. When the snow finally melts, we look forward to seeing our lawns again. Finding patches of rusty pink edged circles or grayish-white spots is never a nice surprise.
Pink Snow Mold
Also known as fusarium patch, it first begins as small yellowish-green spots that can grow out from 6 to 12 inches in diameter. The patches eventually take on a pink coloring along the edges.
If it appears after the snow melts in the spring, it's likely fusarium blight. It loves cool, wet weather, and long periods of cold temperatures make it worse.
Gray Mold
Also known as typhula blight, it first shows up like fusarium patch as yellowish-green spots. They can become as large as 2 feet in diameter and grow together becoming large infected areas. As these patches increase they take on a grayish-white coloring.
Grass Blades
The infected grass blades of both types will become matted turning a light tan color. The gray mold blades have raised spots on leathery blades.
