What’s the all the fuss about Snow Mold?
Snow mold is a type of fungus that damages or kills grass after snow melts. Damage can come in a circular form with multiple spots, or over a widespread area. Snow mold comes in two varieties: pink or gray. Snow mold can manifest based on a number of different criteria. The most common are:
- A large amount of snow cover over an extended period of time
- Your lawn was not mowed short enough last fall
- Your soil is wet and holding moisture
- Your soil lacks good biology to combat the fungi that causes snow mold.
There are some sound cultural practices that can be done first thing in the spring when the snow melts away which are beneficial for the turf, and specifically, the areas damaged by snow mold. Your lawn should be raked (de-thatched) to remove any leaf debris and also to fluff-up matted down patches of turf, improving the air movement around the turf. Debris should be removed for ideal exposure. Aeration can help to break apart excess thatch and help to increase air flow and provide beneficial water and nutrients to the grass roots. An application of fertilizer in the infected patch can also help to boost recovery. A lawn care program with consistent fertilizing and weed control throughout the season will help to keep this area as green as possible, while eliminating weeds that tend to thrive in thin turf areas.
If no recovery is seen, reseeding is likely needed. You’ll want to rake away matted down grass so that seed has good contact with the soil below for ideal germination. And as always, don’t forget to water after seeding!
