Now that spring is starting the snow is melting and we are finally starting to see the refreshing sight of grass and now is the time to check your lawns for snow mold.
This years winter has been a perfect winter to promote the growth of snow mold. The early heavy snow falls before the grass got to go into full dormancy, the the amount of snow we received this year led to large snow piles, and and the slow thaw so far this spring is keeping the lawns wet making favorable conditions for snow mold to develop.
There are two kinds of snow mold Gray Snow Mold and Pink Snow Mold.
Gray snow mold is usually the most common that you will see. As you can see in the picture gray snow mold almost appears like a gray spiderweb
over parts of your lawn.
Pink Snow Mold is usually more rare and can be more severe then gray snow mold. Pink snow mold appears in a circular reddish-brown patches.
What should I do if my lawn get snow mold?
If you spot snow mold in your lawn it is best to rake the areas to uncover the grass underneath allowing it to breath. Aeration & Dethatching can be used to break up the snow mold. In some cases if the snow mold is bad over a large area fungicides may be required. After the grass starts to green up inspect the areas most affected by the snow mold and see if the grass is growing in those areas. If snow mold killed some patches of your lawn overseed them with a high quality Kentucky Bluegrass, Fescue grass seed mix as they are less prone to snow mold.
What can I do to help prevent snow mold?
*Proper timing of your fall fertilizing application. Fall fertilizing is the most important fertilizing application but needs to be timed correctly to not cause excess growth.
*Make sure to keep mowing your lawn tell it stops growing and to make your last cut of the year much shorter then you had been cutting it throughout the year. Leaving your grass long over the winter will allow the snow to mat the grass down and promote snow mold.
*Doing a fall cleanup at the end of the year. Excess leaves left on the lawn will mat the grass and promote snow mold.
*Large snow piles in the lawn left by snow plows is a great way to promote snow mold. Use a snow blower to help spread the snow over a larger area and to not create large piles of snow.
