The Red Thread fungus disfigures lawns in the right conditions; thunderstorms, heavy rain and warm weather combine to raise humidity levels making you, me and the lawn feel a little sticky! This is an ideal environment for fungus to grow and eat the leaves of your lovely lawn!
• It is already active in many places…
Rain and warmth will increase humidity and therefore the severity of attack.
• Patches of lawn will go straw coloured.
• The spores can spread so limit lawn maintenance to mowing and feeding.
What to do about it:
• Fertiliser is the main defence, promoting growth so that fungal damage gets mown out relatively quickly.
• If you’ve recently received a treatment with our slow release granular fertiliser your lawn should be green and prepared but, depending on the severity of the outbreak, further help may be required.
• If your lawn has not recently been treated, your Nutrilawn Greenkeeper will notice the pathogen and apply treatment at the higher rate to help repair leaf damage.
• However, Fertiliser alone will not provide sufficient nitrogen to stop the pathogen in it’s tracks. An application of fungicide – available from us – will stop the pathogen from spreading. A second application may be necessary depending on the severity.
Other things that reduce severity:
• Remove clippings after mowing.
• Water deeply and infrequently only if conditions are dry.
• Do NOT water in the evenings.
• DO NOT rake or scarify the lawn as you will increase damage and spread the fungus!
• Once the disease has ceased activity – usually August or September, Aeration and possibly scarification will help to improve drying and remove thatch that harbours fungal spores.
Our Autumn/Winter Treatment will also help.
