What Is Snow Mold?

Yes, snow mold is a real thing.

It may not be what you are picturing in your mind. Visions of green snow or odd growths appearing on your snowman would be far from the truth.

Snow mold is a lawn disease which shows up when an area of turf remains too wet, for too long, during colder months. Do you find yourself asking "What does it look like?" or "How can I prevent snow mold?" Well, we answer these questions and more below.

Why does snow mold happen?

The most favorable condition for snow mold is a Snow Moldcold damp spot underneath snow or leaves for a period longer than 40 days. When the snow on your lawn begins to melt and as the daytime temperature reaches between 30°F and 45°F, snow mold can begin to spread rapidly. Conditions worsen in areas where moisture is abundant, such as protected, shady, depressed areas.

What does snow mold look like?

Snow mold will look like spots of color on your lawn which can begin as yellow-green and change to grey, white, or even pink. As the mold spreads, the outer rim of the circle will begin to turn grey to rusty pink and even run into other circles, forming a larger affected area.

How to prevent snow mold:

  1. Rake leaves in the fall and mow the grass before it snows. Leaves and tall grass act as a layer of insulation, creating an ideal breeding ground for snow mold.
  2. Introduce disease resistant grass types to your lawn when seeding.
  3. Use a slow release organic-based fertilizer when it gets closer to winter. Fertilizers with lower levels of nitrogen are best because they won’t promote as much top growth.
  4. Have your lawn care technician take a soil sample or check your current sample results. A neutral to slightly acidic soil is ideal to minimize snow mold, so an adjustment to the pH level of the soil may be needed.
  5. Improve air circulation over the turf by pruning trees and ornamentals.
  6. Aerate the lawn in fall to reduce thatch and minimize the insulating layer of dead grass.
  7. Prevent excess water from sitting on the lawn through proper grading and drainage.

If your lawn already shows signs of snow mold, don’t despair. It will likely go away on its own when temperatures increase. This spring, rake out any dead grass and ask your lawn care technician to re-seed your lawn or repair bare spots when the time is appropriate. Be sure to follow the prevention tips above for next year as well.

Thanks for helping me transform an “ugly duckling “into a “swan”.  You deserve the “Best in Yard Improvement Award!

Gail Meador – Glen Allen, VA

A walk around my yard compels me to set aside time to tell you how pleased I am with the condition and appearance of my lawn.  I have heard for years that one could not establish a decent lawn in Richmond without devoting a tremendous amount of time, energy and money to getting it done.  I took that as a challenge.  Despite my best efforts, including a fair run with another lawn care service, the results were disappointing.  I began to believe that story.
 
My experience with NaturaLawn of America, however, belies that lore.  Since I started with you last year, the improvement has been miraculous.  My lawn is thick, green, nearly devoid of weeds and growing in spots it never grew before.  It’s the best looking lawn in the neighborhood! In addition, with two indoor/outdoor pets, my wife and I have far fewer concerns about health risks for them because of your system!

Joe Sullivan – Richmond, VA

My lawn is beautiful.  It has never looked this good.  It looks like lush green velvet.  We only had one dandelion this spring and it was on the edge of our property, so it must have been the neighbor’s!

Jennifer L. Lloyd – Bear, DE

We have been very pleased with NaturaLawn of America.  The service is prompt and friendly.  The results have been gratifying.  Our lawn looks lush and green and we have received many compliments.  I highly recommend the service.  And of course, it’s organic-based!

George Reed – Newton, CT

Our lawn looks fantastic! Please continue the no-chemicals approach for my lawn! Thanks!

Julie Hepburn – Leawood, KS

For over 22 years, NaturaLawn of America has been creating naturally beautiful lawns that are safer for you, your family, pets and the environment.  Of course our satisfied customers say its best!
 
In less than a year, my lawn has gone from one of the worst on the block to among the best.  This is quite an accomplishment considering we have well water and, therefore, never water the lawn.  The  service is also top notch – friendly, knowledgeable and always willing to explain why they’re doing what they’re doing.

Stewart Kaufman – Southbury, CT

NaturaLawn of America has cared for my lawns now for 10 years (2 houses) and I am completely satisfied with your company.  My service technician is friendly, caring and knowledgeable.  I’m happy with the results, how you care for my lawn and the prices you charge – happy enough that I recommend you to others and I tear up ads from competitors without even reading them.
 
My husband and I are currently acquiring a house in New Hampshire.  There is no question that I will want NaturaLawn of America service at that house.  It is a true pleasure to work with a “national” company that treats their customers in a local business manner.

Anne Bullitt – Newark, DE

I’m just dropping you a note to let you know that we are very pleased with your lawn service, the way we are treated and the beautification of our lawn.  Many families have seen our lawn and are very impressed by the way it looks.  They are even more impressed that you are an organic-based company and use 85% less chemicals and pesticides.  We have referred many of our friends and neighbors and will continue to refer people as the opportunity arises.

Jack & Sherrie Decker – Plainview, MN

Our lawn is beautiful.  Thank you for the great results AND for protecting my family and the environment from unnecessary chemicals and pesticides.  It’s nice to have a lawn care company that is concerned about my lawn, my family and the environment.  When people are looking for a healthy, nice lawn, friendly service AND a safer lawn care option, I highly recommend they call NaturaLawn of America.

Pete Plimmer – Wilmington, DE

You are doing a great job! We are glad we switched to NaturaLawn of America and are spreading the word about the super job you do.

Steve Pfannenstein – Rockville, MN

I just want to thank you for all the years of guidance and wonderful service that you provided to us.  As first-time homebuyers, we were unaware of the constant maintenance a lawn requires.  We have been using your service since 1997 and our lawn went from dirt to a plush velvet yard.  We have received many compliments on our wonderful yard – thanks to the service you provided year after year.  We have and will always continue to recommend you to others.

Michele Sawyer – Richmond, VA

Our yard was in terrible shape when we bought our home.  Being first-time homeowners, we were unsure how to tackle the daunting task of improving our yard.  We contacted NaturaLawn of America for assistance.  Within a week, they were at our home beginning the process of turning our yard around.  After 2 weeks we saw significant improvement.  We are extremely happy and couldn’t be more pleased with the service and dedication that NaturaLawn of America has shown in turning our yard around.  We would recommend them to anyone!

Brian Cleland – Belleville, IL

The family who built our three-year old house was unsuccessful in two attempts to seed a lawn.  Our grass was in terrible shape; but as a mother and pet owner, I was unwilling to load it up with nasty chemicals.  Instead, I called NaturaLawn of America.  We now have a beautiful healthy lawn that I can feel good about.  And my husband touts our “organic” lawn to anyone who will lend and ear.

Susan Horne – Aurora, OH

I wanted to write and let you know how pleased I am with NaturaLawn of America.  I had never used a lawn service before.  I’m against putting more chemicals into the environment, so I decided to see what you could do organically.  My lawn was 1 ½ years old – builder grade seed on builder soil! It was a lawn in need of some help, but I didn’t know how wonderful it could look.
 
Two days ago, my neighbor (who used one of the top chemical lawn companies) sounded a little baffled and asked what I do to my lawn – It looks like a carpet!  We just smiled and said “NaturaLawn of America”.  That’s when I took a good look at my lawn and everyone else’s - our lawn is thick and green.  Despite the recent drought, despite our lack of attention to our lawn, and despite its humble beginnings, it is a magnificent piece of work.

Paul & Doris Pavlichek – Mount Airy, MD

This is our second year with NaturaLawn of America and I can’t say how much we appreciate your work. The yard is awesome!

Don Strei – Elk River, MN
