What is Red Thread?
Red Thread is a grass fungal disease that affects grass when the lawn is under stress, such as during drought, periods of high humidity, or improper mowing practices. It gets its name from the distinctive reddish-pink threads or strands that form on the grass blades.

How to Recognise Red Thread
Reddish-brown patches of thinning grass, often with fine red threads or pink, cotton-like particles at the base of the blades. Infected areas appear ragged and may mix with healthy grass.
In severe cases, grass looks scorched or yellowed, with irregular patches from 5 to 50 cm wide, sometimes merging into larger areas.
How Did My Lawn Get Red Thread?
Although high humidity is the main cause, several other factors can contribute to the development and spread of Red Thread.
- Moisture: Excessively wet or humid conditions create an ideal environment for the fungus to thrive.
- Low nutrition: Grass lacking in nutrition is more susceptible to red thread infection.
- Low Mowing Height: Cutting the grass too short weakens it and makes it more vulnerable to diseases.
- Poor Air Circulation: Lack of airflow and poor drainage can create a conducive environment for the growth of red thread.
