What is a Lawn Disease?
Lawn diseases are nearly almost a lawn fungus. If the lawn disease isn’t identified and treated it can spread and damage your entire lawn.
What Lawn Diseases can I find in my garden?
There are many common lawn diseases that are found in gardens throughout the UK – these include:
Red thread is one of the most common lawn diseases. It occurs in lawns that have poor light and soil or after periods of heavy rain, where the rain-washes the nitrogen from the soil depriving the grass of its vital nutrient.
You normally see red thread appear during late summer, where you will be aware of reddish patches of grass appearing in your lawn. Red thread is a leaf disease more than a soil disease; although it can live in the soil up to 2 years before it germinates, it is relatively easy to eradicate and the lawn will recover over time.
Commonly known as snow mould, fusarium patch is likely to appear in lawns after a long period of the grass being covered by snow. The disease forms due to wet, humid climate conditions. When the disease first appears you could notice a small circle shape, like a tennis ball, in your grass in a creamy straw like colour. Whilst the disease is actively growing the outer circle has a slimy texture, this can make the circles look like an irregular shape and some might say even look like clouds.
If you have Fusarium and it’s not treated during the winter and spring, it will survive the summer months lying dormant within the thatch in your lawn. Once the correct weather conditions arrive it will attack the living blades of grass within your lawn. It can spread quickly through lawnmowers, feet and any wheelbarrows etc.
