Lawn Fungus Treatment & Prevention

Everything, sooner-or-later, gets sick. A whale sneeze can wipe out a small town. When a chicken gets a cold, watch out. Everything is susceptible to disease. Even your lawn. While your lawn cannot get Athletes Foot because you walked across it without wearing your flip-flops, it can catch other types of fungus.

  1. 1.Identifying Lawn Fungus

    Lawn fungus has many colors. Red, pink and gray are common shades. Throw in the region of the country that you reside, and you begin to see that there are a lot of different dimensions to the elimination of fungus.


    Lawn fungus has strange ways of acting. It really all depends on what kind of turf you’ve planted (that works best for your location). Then there’s the weather, water, over-care and over-feeding.


    To learn more about lawn fungus in general, and reasons why you may have it, see our article Why do I have Lawn Fungus?

  2. Unless you’re not permitted to soak your lawn because of city regulations, the optimal time to water the lawn is in the morning.
  3. 2.Prevention

    “An ounce of prevention is worth a pound of cure.” The best way to deal with the lawn blight is to stop it before it starts.


    You need to get some fertilizer that contains a fungicide. Find a material which is called a systemic fungicide. That means it’s a chemical that’s actually absorbed by the grass. Because of the fungicide and the grass becoming one, it stays in the tissues of the blades for a period of time. That’s why you should get in the habit of sprinkling a systemic fungicide every spring and fall.

  4. 3.Nitrogen

    Too much of a good thing always has unintended consequences. An example in this case might be putting too much high nitrogen fertilizers on your lawn. Overdoing it will lead to fungus. As always, read the label of the materials you buy.


    Try to commit to memory these three consonants, N.P.P. When you're looking for fertilizer you will see three numbers somewhere on the product. It looks like this: 12-12-12 or some variation on that theme. Here’s the key. The first number tells you the nitrogen content, the second is phosphorous and the third is potassium. Good fact to know whenever you’re planting anything and you want to feed it more than water.

  6. 4.Wake-Up and Water!

    Unless you’re not permitted to soak your lawn because of city regulations, the optimal time to water the lawn is in the morning.


    When you water the grass late-in-the-day, it’s soon going to get dark. Even a full moon can’t help evaporate the drink you just gave the lawn. If you know a little about Athlete’s Foot, same principle – fungus grows in a moist place.

  7. 5.Maintenance

    Practicing good hygiene with your lawn pays-off. Make sure the blades on your lawn mower are ninja sharp. Don’t leave leaves, sticks and other yard waste sit around. Either dump it or create a mulch pit.Punch some holes in your grass once-a-year. Rent an aerator at your local home improvement store. Hiring a lawn care specialist is worth considering. They’ll come out every couple of weeks and make sure things are in order.
