The conditions that are favorable to snow mold is when we have heavy snow fall on cool season grasses in years when the first snow fall is on ground that is not yet frozen.
This leaves a layer for mold spores to develop and lay dormant between grass and snow. When temperatures rise and snow melts, the dormant spores will become active.
Have no fear - the effects of this disease are not extreme at all and can be remedied with some minimal raking and preventative measures. Snow mold can trigger allergy attacks as it is exposed when snow melts so we still want to be careful of this even though it’s not terribly damaging to your lawn itself.

Circular patches of dead grass
Bleached to tan-colored areas up to several feet in diameter

Apply Nitrogen during summer and fall to avoid disease growth in winter.
Maintain a lower soil pH and balanced soil fertility.
Mow grass at low height until it goes dormant before winter
Lightly rake out affected areas.
Grass will not regrow in areas affected by Pink Snow Mold - reseeding these patches might be necessary.
Rake all leaves before first snow fall. Leaves left behind will create a soggy environment for spores to develop.
Remove snow drifts. Snow drifts hang around long and melt slower, promoting a damp environment for mold production.
Bottom Line: Like many other lawn issues - this can be prevented with a few very simple preventative measures. To greatly reduce the chance of snow mold in your lawn, call your local trusted lawn care professional for fertilization treatments. If planning to tackle the problem on your own, be persistent. Be sure to stay on the easy-at-home preventatives to reduce the chance of snow mold in your lawn.
