There are a number of signs to watch out for that indicate a problem with your lawn, and some of them are more obvious than others. In most cases, discoloration is the most obvious sign, as grass will turn yellow, tan, or brown in spots. Keep in mind, though that its not always a disease that can cause this. Higher than normal temperatures, inadequate watering, and insects can also cause dead or dying areas, only underscoring the need for adequate identification.

Assuming that everything else is normal, discoloration is just one sign that your lawn is sick. Brown patches not attributable to pets, slimy patches of grass, a film covering the grass and spots on individual blades of grass are all signs of an issue.

Well cut out the guesswork for you so you can focus on enjoying your outdoor spaces.

    How To Prevent Fungus

    Water early in the day

    Watering early in the day will allow your lawn to absorb the water and then dry off throughout the day. Watering late in the day or in the evening does not allow the lawn to dry and will promote fungus. Because fungus moves through water, a wet lawn will allow fungus to spread much faster.

    Sharpen mower blades

    It is always important to mow with sharp mower blades, but especially so when trying to prevent fungus. A dull blade can shred the grass blades leaving many openings for disease to enter.

    Raise mowing height

    When mowing, do not remove more than of the grass blade. This will allow the grass to stay healthy and strong. Scalping the lawn stresses the root system.

    Dont over or under fertilize

    Use high nitrogen fertilizer only in the spring. High nitrogen in late October/November will promote snow mold next year. When lawns have the right nutrients they need to grow, they are less susceptible to disease. Diseases such as red thread can often be controlled by adding nitrogen to your lawn.


    Thatch is a layer of organic matter between the crown of the grass plants and the soil layer. Thatch can appear as a result of an imbalance in your soil or improper lawn maintenance practices.

    We recommend removing thatch in the fall. Thatching brings up weed seeds and these are more prevalent in the spring. Use a heavy rake or thatching machine as needed to keep thatch to a minimum. The regular use of organics will help to keep thatch in order.

    Freeze-tolerant fungi can develop on any species of lawn grass in locations with cold, wet, and snowy winters, resulting in pink snow mold and gray snow mold . Snow mold-causing fungi can be found in almost any soil, but the damage they inflict is slightly different in both cases.

    • There are often dead areas of snow mold with a pale gray or white bleached appearance under enormous snow drifts, which can be classified as gray snow mold. Soggy grass and moldy mold are a result of snow drifts melting more slowly than the surrounding snow. Patches of gray snow mold can range in size from a few inches to several feet across. It is possible for gray snow mold to damage the grasss roots if the soil remains moist for long periods of time, but in most circumstances, only the surface blades of the grass are affected.
    • As a result of pink snow mold, circular dead patches with pinkish or rust-colored borders are formed. In a long, rainy spring or a particularly wet fall, pink snow mold can begin to form if the grass is chilly and wet . Pink snow mold can flourish all winter under a coating of snow, causing broad damage to the grass if it starts growing in the fall. This pink snow mold can generate spots of less than 12 inches in diameter, yet they can appear in large numbers throughout the lawn. Patches of pink snow mold-infected grass will not grow back.

    • Excess nitrogen can cause fungal growth on your lawn, so understanding the current nutrient levels and how to correct them will help. Things like over-fertilizing your lawn can cause excess nitrogen levels, so be mindful of how much youre applying.
