Snow mold shows up where snow lingered on grass—often along drift lines, shaded edges, or north-facing patches. Two common types are **gray snow mold** (*Typhula*) and **pink snow mold** / Microdochium patch (*Microdochium nivale*). Both can leave matted, bleached, or discolored turf as snow melts. Spring work is recovery; most of the prevention happens in fall—see the [cool-season snow mold prevention checklist](/articles/cool-season-snow-mold-prevention-fall-checklist).

## Key takeaways

- **Gray (*Typhula*)** vs **pink (*Microdochium*)**: both leave flattened mats after melt; pink snow mold can also flare in cool wet weather **without** deep snow (Illinois Extension themes).
- **First DIY moves:** let patches dry, **rake lightly** to open the canopy, clear heavy leaf/thatch debris, and hold a heavy nitrogen shock until you see how much crown is alive.
- **Reseed** only where crowns are dead and soil shows through—spring seed works but competes with summer annuals; weigh that against waiting for [fall overseeding](/articles/fall-overseeding-cool-season-lawn-timing).
- **Next fall:** keep mowing until growth stops, manage leaf mats, and time nitrogen sensibly—full checklist in [snow mold prevention](/articles/cool-season-snow-mold-prevention-fall-checklist).

## What you are seeing

- **Circular or irregular patches** of flattened, crusty grass.
- **Cottony or webby growth** in cool, wet weather (more typical of gray snow mold); sometimes dark **sclerotia** in gray-mold debris (Illinois HortAnswers).
- **Pinkish cast** when active—often associated with pink snow mold / Microdochium patch.

Identification from photos alone is imperfect; if patches are severe or spreading in warm weather, your local extension office can help narrow it down.

## Recovery steps after melt

1. **Let the area dry** when possible; avoid walking through saturated patches repeatedly.
2. **Rake lightly** to break matted blades and help sunlight and air reach the crown. You are not scalping—just unsticking the turf. A [leaf rake](https://www.amazon.com/s?k=leaf+rake&tag=lawnjournal0c-20) is enough for most mats. As an Amazon Associate, Lawn Care Journal LLC earns from qualifying purchases.
3. **Bag or remove heavy debris** if thatch is thick and holding moisture; compost off-site if your municipality allows diseased clippings.
4. **Avoid heavy nitrogen** until you see how much live grass remains. A stressed lawn does not need a shock of fast growth—save planned feeding for the [fall nitrogen window](/articles/cool-season-fall-nitrogen-fertilizer-timing) once recovery is clear.

## When to reseed

If crowns are dead and soil shows through, plan reseeding with a species mix suited to your site and season. For cool-season lawns, spring seeding can work but competes with summer annual weeds—your tradeoff depends on region and weed pressure ([pre-emergent vs spring overseed](/articles/pre-emergent-vs-overseed-spring-cool-season-lawn)). Patch repair may mean loosening soil, [cool-season grass seed](https://www.amazon.com/s?k=tall+fescue+kentucky+bluegrass+seed&tag=lawnjournal0c-20), light topdress, and consistent light watering until establishment.

## Ongoing prevention ideas

Prevention is a **fall** job. The short list:

- **Avoid excessive late-fall soluble nitrogen** that pushes lush growth under early snow—Illinois HortAnswers ~**6 weeks** before killing frost / first snow.
- **Continue mowing** until growth stops; Illinois winter-damage guidance often cites a final height near **~2 inches**.
- **Mulch moderate leaf drop; collect thick mats** so unshredded blankets do not sit under snow—see [fall leaf mulch vs collect](/articles/fall-leaf-mulch-mowing-vs-collect-cool-season) (UMN / Purdue framing).
- **Improve drainage** where puddles form; reduce chronic plow piles on the same soft turf when you can.
