How to Treat Lawn Fungus: Identifying and Treating Common Lawn Fungal Diseases
A lush, green lawn is a hallmark of a well-cared-for home, but fungal diseases can quickly undermine your efforts. These diseases can turn your beautiful turf into a patchy, discolored mess if left untreated. The key to maintaining a healthy lawn is early identification and prompt treatment of fungal issues. In this guide, we’ll cover common lawn fungal diseases and how to treat them effectively.
Identifying Common Lawn Fungal Diseases
Brown Patch
This disease presents as large, circular patches of brown or tan grass. The affected areas may appear water-soaked and slimy. Brown patch thrives in hot, humid weather, especially when night temperatures remain above 60°F. To identify it, look for irregularly shaped patches that can grow several feet in diameter.
Dollar Spot
Dollar spot is characterized by small, silver-dollar-sized spots of bleached grass. It is common in warm, moist environments and is often seen in lawns with low nitrogen levels. These spots can merge to form larger patches, giving the lawn a scorched appearance.
Red Thread
Red thread appears as pink or red threads on grass blades. It favors cool, moist conditions and often appears in late spring and early fall. Look for reddish-pink mycelium on the grass blades, which gives the disease its name.
Causes and Conditions for Lawn Fungal Diseases
Lawn fungal diseases often arise due to a combination of factors:
Excessive Moisture: Overwatering or poor drainage can create the perfect environment for fungal growth.
Improper Mowing: Cutting the grass too short can weaken it, making it more susceptible to disease.
Over-fertilization: Too much nitrogen can encourage disease outbreaks.
Weather Conditions: Humidity and temperature swings can foster fungal development.
Preventative Measures
Proper Mowing Practices
- Keep your mower blades sharp.
- Mow at the correct height for your grass type, typically around 3 inches, to encourage strong growth and reduce stress.
Watering Guidelines
- Water deeply and infrequently to encourage deep root growth.
- Water early in the morning to reduce the length of time grass stays wet.
Fertilization Tips
- Use balanced fertilizers and avoid excessive nitrogen.
- Follow a fertilization schedule appropriate for your grass type.
Soil Aeration
- Aerate your lawn regularly to improve soil structure and drainage.
- This helps reduce compaction and allows air, water, and nutrients to penetrate the soil more effectively.
Treatment Options for Lawn Fungal Diseases
Cultural Practices
To address the underlying causes of fungal diseases, adjust your watering, mowing, and fertilization routines. Improve air circulation by pruning surrounding plants and removing debris.
Organic Treatments
Consider applying natural fungicides like neem oil or compost tea. Increasing the diversity of beneficial microorganisms in the soil can also help naturally combat fungal pathogens.
Chemical Fungicides
Use fungicides as a last resort and follow the label instructions carefully. Applying fungicides during the early stages of the disease yields the best results.
Professional Lawn Care Services
For persistent or severe fungal issues, consider hiring professional lawn care services. Professionals can diagnose the problem accurately and apply the right treatments safely and effectively.

- Consistent Watering Schedule: Adjust your watering based on the season and weather conditions.
- Regular Mowing: Mow at the correct height and frequency to keep your lawn healthy.
- Fertilization: Follow a regular fertilization schedule to provide essential nutrients.
