Disease Control

Whats Happening To My Lawn?

There are numerous diseases that can affect grass. Below are some of the most common ones. Most diseases are spread by spores and relate to lawn, soil conditions and are helped if your lawn grass is in poor health. Control is achieved by using either a fungicide or correcting some of the issues that cause the disease by cultural means. The best way to prevent these lawn diseases is to have a regular lawn maintenance programme in place. Regular feeding, weed control, aeration, scarification, top dressing and moisture control, along with a good grass cutting regime, will help to keep the lawn balanced and reduces the risk of disease.


Scorching can happen in high temperatures. When fuel or another chemical is spilt onto the lawn. Bitch urine will also scorch a lawn. If irrigaton doesnt regenerate the lawn, the area will need to be raked to remove the dead matter. Grass seed is then re-sown and watered in to germinate.

Dead/Dry Patches

Dead patches can be caused by spills, wear and tear or leaving items on the lawn blocking light. Other causes are disease, pests, lack of water, scorching from the sun, or mowing mowing incorrectly. Most typically they are formed by a fungal growth known as dry patch. The surface layer of the soil becomes repellent to moisture, dries out and kills the lawn.

Fairy Rings

Fairy rings are often caused by dead roots beneath the soil. As the root decomposes it develops mycelial spores that work their way up to the soil surface which become repellent to moisture, They are not easy to deal with. Treatment is either with a fungicide or by excavating the whole area and laying new turf and soil. Both options can be expensive. Brushing away surface fungi growths using a brush will keep further spore production under control.

Rust Disease

Rust disease is very common and is caused by a fungal infection. It usually appears in early spring or autumn when the weather is warm and wet. The best way to control a rust infection is by improving the strength of the grass through regular lawn maintenance. Keeping your lawn fertilised, watered, aerated and mown correctly will improve the ability of the grass to fight any infections itself.

Red Thread

Red Thread is possibly the most common lawn disease found in UK domestic lawns, and attacks the grass from May onwards, although early and late summer temperatures are ideal. High humidity, poor fertility and or blunt lawn mower blades smashing the grass ends are usually the main 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.

Fusarium Patch

Microdichium nivale also known as pink snow mold – Microdichium patch or Fusarium patch is the pathogen that changes as it takes hold and can appear as pink patches that evolve to white snow mold. It primarily affects cool season grasses by affecting the leaves. It typically lives within the thatch layer over the summer but also within the soil and shows itself in cooler periods of winter and early spring. Wind and water can help the spread of this disease by spreading the spores of the fruiting pathogen to infect nearby healthy plants. The disease can become very severe if allowed to spread. Its best to manage by reducing growth effectively encouraging dormancy so limit Nitrogen completely. Raise the mowing height of the mower and reduce moisture levels. This can be done with aeration and scarification to remove diseased thatch and help the lawn surface dry faster. Then treatment with the correct fungicide.

Over Fertilization

This is what happens when you overdose a lawn with fertilizer or herbicide. It will effectively kill and ruin the lawn. It may also cause untold damage to the living soil organisms of the soil food web. This is why its best to use a lawn company and take care when treating a lawn.

White Patches

This is what happens when objects are left on the lawn blocking light. Light is essential for photosynthesis and with out it the the pigment of the grass plants turn white rather than green. If left for long periods the plants will eventually shut down and die so its really important to remove objects in particular large amounts of leaves as without the light the plants cannot produce glucose. Green plants make food in the form of carbohydrate by combining carbon dioxide and water which is hydrogen and oxygen using the energy of the sun. Carbohydrates are chemicals that contain the elements carbon, hydrogen and oxygen to make the simplest form of carbohydrate which is a glucose sugar. So help your lawn by moving objects such as play equipment regularly to avoid weakening your lawn.
