It’s Earth Day!

What is Earth Day?

Earth Day is an annual observance celebrated on April 22.  Events are held worldwide to demonstrate support for environmental protection.

How did Earth Day start? 

Wisconsin Senator Gaylord Nelson and peace activist John McConnell proposed a day to honor the earth and the concept of peace.  In 1970, the first Earth Day was celebrated.  Nelson was later awarded the Presidential Medal of Freedom for recognition of his work.  Earth Day was then launched internationally in 1990 by Denis Hayes.  Millions of people worldwide now participate in Earth day.  The most common celebration is to plant a new tree.

So get off the internet and go outside and enjoy nature!  That is what today is all about!

Snow Mold?

Published on

Your lawn was perfect last fall. You spent all summer tenderly caring for your grass.  The harsh winter weather with it’s snow and ice arrived, but you weren’t worried.  You knew you had taken all the right steps to ensure a beautiful lawn in the spring.  But, as spring draws closer, you look through your window at your lawn and you can’t believe it.  There are large patches of matted, pale, straw-colored grass everywhere.  It’s Snow Mold!!


Snow Mold lawn disease can infect almost any grass that is subject to freezing temperatures and snow cover. It is often the first disease of the year and may cause your lawn to have circular, straw colored patches when the snow melts in the spring.  The patches can continue to enlarge if the grass stays cold and wet.  The grass is typically matted and the snow mold may begin to turn white.


Controlling snow mold is easy if the infection is not severe. Generally, the affected areas are just a little slower to green up.  A gentle raking of the matted area will loosen the grass and allow air to circulate near the grass roots, allowing it to grow. Be sure to rake lightly, so that the turf is not uprooted.  It is NOT recommended to use a power rake.  It is also a good idea to reduce any piles of snow that remain, especially in shady areas.  The longer the snow sits on the grass, the more likely that snow mold can develop.  The easiest way to reduce the snow piles is to simply spread the snow out to encourage quicker melting.


Snow mold does not occur in the lawn every year.  It is most common during years when an early, deep snow cover prevents the ground from freezing.  Preventive maintenance before lawn repair is needed is usually the best answer when dealing with most diseases. This is true for Snow Mold. Follow a balanced fertilization program that provides the necessary nutrients at the appropriate times of year. Thatch management is another important key in Snow Mold prevention. Practice core aeration of your lawn at least once a year to keep thatch levels below 1/2″. Another important factor is mowing the grass short before winter. Cut the lawn to 1-1/2 to 2” at the last mowing. This should be a gradual process and not a one-time exercise. Lower the height a notch a week until the mower is set at 1-1/2 to 2”. This will prevent the turf from laying over on itself, increasing the chance of Snow Mold.
