Red thread disease
Red thread is usually seen as large patches of tan coloured turf. You may also see bright red threads on the grass blades within the patches, which is where it gets its name. The disease is caused by a fungus, which normally you don’t see, but it may appear when conditions are very humid or wet and it will usually affect lawns which have not been cared for correctly and are lacking in nitrogen.
If your lawn is affected by Red thread, the best way to tackle the disease is to:
- Apply a suitable lawn fertiliser to increase nitrogen levels
- Regular mowing – little an often is best, aiming to keep the height at approximately 25mm
- Cut back surrounding foliage to improve air movement across the lawn which will help to reduce moisture levels
