Yikes! What the heck happened to my lawn? The grass is all matted down and instead of a healthy green color; it’s turned a sickly grayish-tan and unnatural pink. As an advanced Master Gardner with the University of Idaho, I quickly discovered it is Snow Mold. It’s a fungus.
There are two types of Snow Molds, gray and pink. The gray Snow Mold is known as Typhula blight. The pink Snow Mold is called Fusarium patch. It most likely grew on my lawn, and maybe yours, because we got some early snows that landed on unfrozen ground and the snow stayed through February.
Once more, we can blame it on the crazy winter we all just put behind us. While Snow Mold looks unsightly, there is a fairly easy fix for it. Find all the affected areas of your lawn and gently rake the space and remove all the dead and decaying matter.
Because the snow sat on our lawns for such a lengthy stretch of time, the lawn may need a little coaxing and a lot of TLC. You could spread a little fertilizer, as this will help promote new growth in the areas where you’ve removed the dead grass. You can also treat it with a D&B product called Fertilome F-Stop Fungicide Granules.
If you have to rake away a lot of damaged lawn—as I have, you will need to do at least one more step. Re-seed your lawn with your preferred grass seed. Also, if you haven’t already planned to, set a date to aerate your lawn. This will ensure the healthiest regrowth of your damaged turf.
One last thing, (as if you didn’t need to do more shoveling) … If we get another winter like that of 2016-17, try to shovel off from the grass the piles/mounds of snow. Spread out the snow and give it the best opportunity to melt away. Your lawn will thank you.
