May 2018 Red Thread Warning
Disease Warning for Red Thread
The Red Thread fungus seriously disfigures lawns in the right conditions; recent thunderstorms, heavy rain and warm weather combine to raise humidity levels making you, me and the lawn feel a little sticky!
So, what's on the cards:
- Expect Red Thread - it's already active in some places
- Rain will increase humidity and therefore the severity of attack
- Patches of lawn will go straw coloured
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 fertilised with our slow release granular fertiliser your lawn should be green and prepared
- If you haven't fertilised then the timing is now perfect for a treatment at the higher recommended rate
- If you're between treatments or want to give your lawn a boost use Soluble Fertiliser, however, Soluble Fertiliser alone will not provide sufficient nitrogen to promote the amount of growth required
Ideal Fertilisers are:
Other things that reduce severity:
- Remove clippings after mowing
- Water deeply and infrequently only if conditions are dry
- Do NOT water in the evenings
- Refrain from using fungicide - you will reduce resistance in your lawn and next years attack may be twice as bad!
DO NOT rake or scarify the lawn as you will increase damage and spread the fungus!
Once the disease has ceased being active, usually August or September, aerate and possibly scarify the lawn to improve drying and remove thatch that harbours fungal spores. Finish with an Autumn feed.
