Red Thread Fungal Infection: What to Look Out For and How to Treat it

Red Thread Fungal Infection: What to Look Out For and How to Treat It

As the weather warms up and the summer months begin, lawn owners may notice patches of discolouration, thinning grass, or strange-looking fungal growth appearing in their lawns. These are often signs of fungal infections, which can thrive in the warm, moist conditions typical of early summer. Identifying and treating these infections promptly is crucial to maintaining a healthy, lush lawn.

Red Thread (Laetisaria fuciformis) – A Common Early Summer Fungal Infection

Red Thread is one of the most common fungal diseases affecting lawns in the UK during the early summer months. It usually appears as pinkish-red strands or patches of grass that look like they’ve been covered in thread. This fungus thrives in warm, humid conditions and can spread rapidly if not treated. Red Thread is typically more prevalent in lawns with poor nutrition, especially those deficient in nitrogen.

How to Treat Red Thread

• Proper Lawn Nutrition: Ensure your lawn receives adequate nitrogen to prevent nutrient-deficient grass, which is more susceptible to fungal attacks.
• Improved Drainage: Compacted or poorly drained lawns create the ideal environment for fungal growth. Aerate the lawn and address any drainage issues.
• Regular Mowing: Keep the grass at an optimal height to allow airflow and reduce moisture retention.
• Targeted Fungicide Treatments: For severe Red Thread infections, a professional-grade fungicide may be necessary. Lawnscience’s technicians are all trained and approved to apply professional-grade fungicides.

Preventing Red Thread

Preventing Red Thread involves ongoing maintenance. This includes regular feeding, proper watering practices, and monitoring for early signs of disease. Additionally, regular aeration and scarification can help to reduce thatch build-up and improve overall lawn health.
