Even with consistent care and attention, lawns can sometimes develop problems that go beyond routine maintenance issues. Lawn diseases are often misunderstood and can be difficult to diagnose because their symptoms may resemble poor watering habits, soil deficiencies, or environmental stress. Understanding whether your grass is struggling due to disease or simple upkeep mistakes is the first step toward restoring a healthy yard.
Below are some of the most common lawn diseases seen in Utah, how to recognize them, and what you can do to manage or prevent them.
Brown Patch
Brown Patch is one of the more noticeable turf diseases and is named for the circular brown areas it creates across the lawn. These patches can expand significantly, sometimes reaching several feet in diameter if left untreated. In Utah, this disease tends to appear during cooler, wetter periods—most commonly from late fall through spring—especially when lawns experience excess moisture combined with fluctuating temperatures.
Brown Patch develops when grass blades weaken and collapse, often due to prolonged damp conditions. To reduce the risk of this disease, experts recommend avoiding excessive nitrogen fertilization and instead using moderate, balanced applications. Improving airflow by trimming nearby shrubs and reducing shaded areas allows moisture to evaporate more quickly. Watering should be done deeply but infrequently, preferably early in the morning, to allow grass blades to dry throughout the day.
Pythium
Pythium is a destructive lawn disease that attacks grass roots and thrives in poorly drained soil. This condition often appears as small, circular patches ranging from one to three inches wide and may have a grayish or greasy look. In some cases, white fungal growth may be visible on the surface.
Because Pythium is driven by excess moisture and standing water, it can develop at any time of year in Utah if drainage issues are present—especially after heavy irrigation or snowmelt. While fungicides can help slow its spread, long-term control depends on correcting the underlying problem. Improving soil drainage, reducing overwatering, and ensuring proper grading are the most effective ways to prevent this disease from returning.
Summer Patch
As the name implies, Summer Patch is most prevalent during Utah’s hot, dry summer months. This disease affects the root system and crown of the grass, weakening it from below. One of the defining characteristics of Summer Patch is its “frog-eye” pattern—rings of damaged grass surrounding a center of healthier turf.
Summer Patch can be difficult to diagnose early because its symptoms resemble drought stress or nutrient deficiency. Unfortunately, once visible damage appears, treatment options are limited. Preventative care is the most effective approach. Applying preventative fungicides in late spring—particularly strobilurin or DMI-based treatments—can help protect the lawn before summer heat sets in. Maintaining consistent irrigation during hot periods may also support recovery and reduce further stress.
Dog Spot
Dog Spot is not caused by fungi but is one of the most common lawn issues for pet owners. This problem occurs when high nitrogen levels in dog urine burn the grass, leaving behind yellow or brown patches. This issue affects lawns year-round and is common across all grass types.
There are several practical ways to reduce dog-related lawn damage. Keeping your dog well-hydrated helps dilute nitrogen concentration in urine. Immediately watering the area where your dog urinates can also minimize damage. Many homeowners choose to designate a specific bathroom area for their dog, using gravel or mulch instead of grass to prevent repeated burn spots and lingering odors.
Keeping Your Lawn and Yard Healthy
Maintaining a clean yard plays a vital role in lawn health, particularly in areas frequently used by pets. Removing dog waste promptly helps prevent excess nitrogen buildup, discourages pests, and reduces the spread of bacteria that can harm both your lawn and your family—including your pets.
Of course, convincing someone in your household to take on that task consistently isn’t always easy. That’s where professional help can make all the difference.
