Grass Disease Control
An increasingly common disease which usually occurs in the late summer after periods of warm weather with heavy rainfall producing conditions of high humidity. Lawns with poor fertility are highly susceptible to red thread disease. The grass will gradually show signs of browning off with brown patches of dying grass appearing and you will see red threads on the grass stalks. High humidity, poor fertility and/or blunt lawn mower blades smashing the grass ends are usually the cause of red thread. Serious cases may require an application of fungicide to control the disease. The lawn usually recovers in 2/3 weeks after treatment. Avoid watering late in the evenings as this encourages disease.
These can cause various turf diseases. Fine-leaved grasses such as bents and fescues are more susceptible than rye grass species.
(Commonly called snow mould).The disease is sometimes noticable after thaws of snow hence the name (snow mould), yellowish dying patches then appear in your lawn eventually turning brown. Fusarium patch appears in autumn or during mild winter weather. Lawns receiving too much nitrogen feeds have lots of top growth making them susceptible as are lawns on compacted soil. Aerating and ensuring the grass receives a balanced fertiliser feed program can cure Fusarium patch. Serious infections will require treatment with fungicide.
Dry Patch or Hydrophobic Dry Patch
During periods of dry weather a fungus builds up around the soil particles and will have an effect of repelling the water droplets in the soil. A severe case of dry patch will result in the soil almost being unable to absorb water and any rain will run across the surface of the soil like rain on a glass plate. The grass suffers as moisture is not reaching down to the roots. Aerating your soil by spiking or hollow tine aeration combined with an application of a wetting agent to tackle the fungal disease will improve the water absorption properties of the soil and benefit the grass. Dry patch is an increasing problem in our dry windy summers. Lawn Therapy apply wetting agents in our four seasonal treatments free of charge to help prevent lawns from drying out and help grass make the most of available moisture.
Easily identified by a circle or ring of lush green growth. Depending on the type of fungus causing the fairy ring there may be an area of dead brown grass in the middle of the circle. There are three types of fairy ring and Lawn Therapy can diagnose and advise you on how to treat each type.
Slime moulds usually appear on dead grass as they feed on dead organic matter and cause no real harm.
Mushrooms and Toadstools or Fungi
Fungi are natures dustmen. Fungi convert dead organic matter into basic nutrients that re-enter the food chain and are eventually recycled. A few mushrooms or toadstools appearing in your lawn is a healthy indication that the fungi in your soil are active and breaking down perhaps an old tree root buried on the soil.The fungi appear on the surface and contain spores which are released into the atmosphere. If your lawn has a heavy concentration of toadstools etc then it may be necessary to treat your lawn. However just a few mushrooms here and there on your lawn will not be harmful.
