Red Thread Can Really Spoil The Look Of Your Lawn

If you are noticing your lawn is developing straw coloured patches, about the size of a saucer to a dinner plate, your lawn might well be infected with Red Thread.

Red Thread is the most common of fungal diseases that will attack the majority of lawn grasses. It is a particular problem for perennial rye grass (Lolium perenne), annual meadow grasses (Poa annua) and fescues such as red fescue (Festuca rubra).

This lawn fungus favours mild, damp weather when the canopy of the grass becomes humid, usually during late Summer, but it can develop at any time of the year when the conditions are conducive.

The current wet and warm weather is creating perfect conditions for the fungal disease Red Thread to infect lawns.
