Maintaining a healthy, vibrant lawn is about more than just regular mowing and watering. Even in the lush climate of the Willamette Valley, lawns in Eugene and Springfield are vulnerable to a range of diseases that can quickly turn green spaces into patchy eyesores. Knowing how to spot common lawn diseases early—and how to treat them effectively—can make all the difference in keeping your property thriving. At Living Concepts, we’ve been helping property owners protect their landscapes since 1981, and we know the signs to look for.

Common Lawn Diseases in Oregon

Because of the region’s cool, wet seasons, many fungal diseases thrive in local landscapes. Here are a few of the most common:

  • Red Thread – This fungal disease causes thin, reddish threads to appear across your grass. It often shows up in nutrient-deficient soils and can leave large areas looking weak and dull.

  • Dollar Spot – Named for the small, round, straw-colored patches it creates, dollar spot thrives in humid conditions. Left untreated, it can spread rapidly across your lawn.

  • Rust – Lawns with a rusty orange or yellow powder on the blades are often affected by this disease. Rust tends to appear during dry spells, especially if your lawn is already stressed.

  • Snow Mold – After Eugene’s cooler winters, you may notice gray or pink patches in your grass. Snow mold develops under lingering moisture and often shows up in early spring.

How to Identify Lawn Disease

The first step in treatment is proper identification. Watch for these warning signs:

  • Discolored patches that don’t respond to watering

  • Powdery, slimy, or threadlike growths on grass blades

  • Thin or dying grass in irregular shapes

  • Patches that spread even with consistent care

If you notice these symptoms, it’s best to act quickly before the problem worsens.

Treating Lawn Disease

At Living Concepts, we approach lawn care with both expertise and eco-friendly solutions. Here are some of the most effective treatments:

  • Balanced Fertilization – Many lawn diseases, like red thread, appear in nutrient-deficient soil. Applying the right fertilizer helps restore your lawn’s strength.

  • Proper Watering – Overwatering and poor drainage create prime conditions for fungi. Our irrigation experts can evaluate your system and recommend adjustments to improve efficiency.

  • Aeration & Overseeding – By reducing compaction and introducing healthy new grass seed, you can strengthen your lawn against disease and improve its resilience.

  • Targeted Treatments – In more severe cases, our crews may recommend specialized treatments to control the spread while promoting long-term recovery.
