When your once-lush, vibrant lawn starts to develop patchy, discolored areas, it’s often a telltale sign that lawn disease has taken hold. Lawn diseases can spread quickly, causing significant damage in just a few days if left untreated. That’s why early detection, prevention and timely treatment are critical to keeping your lawn healthy and beautiful throughout the year.

At Massey Services, our GreenUP experts understand that every lawn faces unique environmental challenges—especially in regions where humidity, temperature shifts and rainfall can change dramatically from season to season. Whether your property features St. Augustine, tall fescue, or perennial ryegrass, knowing how to identify and treat common lawn diseases is essential to maintaining curb appeal and long-term turf health.

Understanding the Enemy: What Causes Lawn Disease

Lawn fungi are naturally occurring organisms that typically remain dormant in the soil until conditions favor their growth. Unfortunately, many of these conditions overlap with what your lawn also needs to thrive—moisture, warmth and organic material.

However, when the balance is disrupted, fungal diseases can gain the upper hand. Common triggers include:

• Excessive Moisture: Overwatering, poor drainage or long periods of rain can leave your lawn soggy, creating an ideal breeding ground for spores.
• Thatch Buildup: A thick layer of decaying plant matter between the soil and the grass blades can trap moisture and reduce air circulation.
• Compacted Soil: When the soil becomes too dense, roots can’t access oxygen and water pools on the surface, suffocating the turf.
• Nutrient Imbalance: Too much nitrogen can make grass grow too quickly and weakly while too little leaves it vulnerable to infection.
• Weather Stress: Heat waves, droughts and cold snaps can weaken grass, reducing its natural resistance to disease.

When these factors combine, fungal pathogens can spread fast, producing distinctive symptoms such as yellowing, browning or circular patches of dead grass.

Spotting the Signs of Lawn Disease: Early Detection Is Key

Recognizing the signs of lawn disease early can save you both time and money. Different diseases produce different symptoms, but here are the most common warning signals to look for:

• Circular or irregular brown patches that expand outward.
• Grayish or purplish webbing on the lawn in early morning dew (a sign of fungal mycelium).
• Thinning or yellowing turf despite regular watering and fertilization.
• Soft, mushy areas on the lawn that feel spongy underfoot.
• Uneven color patterns often in rings or arcs.

If you notice these symptoms, act quickly. The longer a disease is allowed to progress, the more extensive the damage—and the more challenging the recovery process.

Common Lawn Diseases: Brown Patch and Beyond

Among the many lawn diseases that homeowners face, Brown Patch is one of the most common and destructive, which is caused by the Rhizoctonia fungus.

Brown Patch: What to Look For

Brown Patch often begins as roughly circular areas of dead or discolored grass, ranging from a few inches to several feet in diameter. Early in the morning, you may notice grayish or purple cobweb-like strands on the surface—this is fungal growth.

The disease primarily targets tall fescue and perennial ryegrass, though Kentucky bluegrass is somewhat more resistant. The fungus thrives in thatch layers, feeding on decomposing organic matter and attacking stressed grass when environmental conditions are right.

Prevention and Control

Since Brown Patch favors excessive moisture, prevention starts with smart lawn care habits:

• Reduce watering frequency, especially during humid or cool weather.
• Mow regularly but not too short—longer blades shade the soil and help resist fungal growth.
• Monitor shaded, damp areas that hold water longer than others.
• Aerate compacted soil to improve air circulation and drainage.
• Use balanced fertilization rather than nitrogen-heavy blends.

Massey Services’ lawn care specialists understand these seasonal patterns and take proactive steps to help your lawn build resilience before conditions become favorable for disease.

Treatment Strategies: Restoring Lawn Health

Once a disease is identified, the goal is to both stop its spread and promote recovery. The following steps form the foundation of an effective lawn disease treatment plan.

1. Adjust Watering Habits

Overwatering is a primary cause of most fungal outbreaks. Water deeply but infrequently, ideally in the early morning so that grass blades dry before nightfall. This limits the time spores have to germinate.

2. Mow with Care

Keep mower blades sharp to avoid tearing grass, which creates entry points for disease. Follow the “one-third rule”—never remove more than a third of the grass blade in one mowing session.

3. Manage Thatch and Compaction

Thatch layers thicker than half an inch trap moisture and encourage disease. Dethatch annually and schedule professional aeration to loosen soil, allowing roots to breathe and absorb nutrients more efficiently.

4. Apply Fungicides When Necessary

In severe cases, fungicides can help control outbreaks. Look for products containing propiconazole, azoxystrobin or thiophanate-methyl—ingredients proven to combat many turf diseases. However, these should be used strategically and as part of a broader care plan, not as a long-term solution.

5. Feed and Strengthen Your Lawn

After a disease episode, your lawn needs nutrients to rebuild strength. Use slow-release fertilizers with balanced nutrition to promote root recovery without overstimulating top growth.

Massey Services tailors fertilization and treatment schedules to your specific grass type, local climate and soil composition—creating a healthy ecosystem that naturally resists disease recurrence.

How to Treat Lawn Disease During Cooler Weather

Many homeowners assume that lawn disease only happens in the summer, but that’s not true. During cooler months, certain fungi—such as large patch, dollar spot and snow mold—can still thrive, particularly when moisture levels are high and growth rates slow.

Here’s how to manage lawn health when temperatures drop:

• Prevent thatch buildup through regular mowing and raking.
• Ensure proper drainage so melting snow or winter rain doesn’t pool on the surface.
• Choose disease-resistant grass varieties suited to your region.
• Apply a balanced winter fertilizer rich in potassium and phosphorus to strengthen roots.
• Treat early with fungicides if signs of disease appear in fall or early spring.

Even as growth slows, your grass continues developing below the surface. Massey’s seasonal treatments focus on root health, ensuring your lawn enters spring strong, dense and disease-free.

Prevention Is the Best Cure

Healthy lawns are naturally more resistant to disease. By taking proactive steps to support soil and turf health, you can greatly reduce your risk of fungal infections. Massey’s team recommends the following preventive measures for every homeowner:

• Water wisely: Deep, infrequent watering builds drought-tolerant roots.
• Mow properly: Adjust height based on grass type and season.
• Fertilize correctly: Apply nutrients at the right time in the right amounts.
• Aerate annually: Prevent compaction and promote air circulation.
• Control thatch: Keep it under ½ inch to discourage fungal growth.
• Inspect regularly: Check for discolored patches or unusual growth patterns.

By keeping your lawn’s environment balanced and stress-free, you reduce the conditions that fungi need to thrive.

Why Seasonal Care Matters

Every season presents unique challenges to your landscape:

• Spring: A critical recovery period when lawns wake up from dormancy. Early feeding and aeration help rebuild strength.
• Summer: High humidity and heat encourage disease; consistent mowing and proper irrigation are essential.
• Fall: Cooler temperatures slow growth, making lawns vulnerable to weeds and fungus like large patch.
• Winter: Root systems continue developing underground. Preventive fertilization and fungicide applications maintain health until spring.

Massey’s year-round care program adapts to these cycles, ensuring your landscape is never caught off guard by sudden weather or disease outbreaks.
