What is Red Thread in a Lawn?
Red thread is a common fungal disease (Laetisaria fuciformis) that shows up as pink or reddish threads on the tips of grass blades. It doesn’t usually kill the grass but makes lawns look patchy and weak.
Why does it occur?
The fungus is present in most lawns and becomes active when grass is stressed. It’s often a sign that the lawn is lacking nutrients, especially nitrogen.
What conditions encourage it?
Red thread thrives in cool, damp weather, particularly in poorly fed lawns, shaded areas, or where soil drainage and airflow are poor.
How do you get rid of it?
The best approach is to strengthen the lawn so it can outgrow the disease. Feeding with a nitrogen-rich fertiliser, aerating, and improving general lawn care are usually enough. Fungicides are rarely needed for domestic lawns.
Key actions:
- Feed with a nitrogen-based lawn fertiliser
- Aerate and scarify to improve airflow and drainage
- Mow regularly with sharp blades and remove heavy clippings
