Unexplained Burnt Patches of Lawn?

If you are concerned about burnt patches on your lawn and have no idea how this happened, you may have to do some detective work.


As a professional lawn care company we visit thousands of lawns and we see lawns that have been burned. Finding out why this happened starts by first asking the right questions and then providing the right diagnosis.

Is your lawn dying for a drink?


Our weather is changeable through the seasons and a downpour of rain over one or two days may lead you to think your lawn has had a good drink. This is not the case though. If your lawn has received 1 -2 inches of rain in less than 30 days and the sun has been hot it may leave your lawn with brown patches. A lawn that has regular watering especially during the hotter weather will be healthier and lush green. Read more about watering your lawn here.

Are there Lawn Diseases on your lawn?


If your lawn is looking a little under the weather it may be infected with a Lawn Disease. All lawns will suffer from Lawn Fungal Disease at some time. Lawn Fungal Diseases will damage your lawn and cause areas of your lawn to badly discolour. Signs of Fungal disease infection will be the appearance of “straw” coloured or burnt looking patches within the lawn, these Fungi can cause areas to discolour very quickly and could take over your lawn.

Are there nuisance lawn pests around?


There are certain insects that are a real nuisance to your lawn. The most common that cause damage to lawns are the Leatherjacket and Chafer Grub. The first signs of an infestation will be an increased activity on your lawn from birds and wildlife, such as badgers and foxes, as Grubs are a perfect meal for them. Other visible signs of Leatherjacket and Chafer Grub damage will be the brown patches and unevenness of your lawn. One way of seeing how damaged your lawn is will be by tugging on the grass, it will lift up very easily. Read more about Leatherjackets and Chafer Grubs here.

Dog urine damage in lawnMan’s best friend?


Your dog might be your best friend, but it’s not always your lawn’s best friend. A number of our customers ask why straw coloured patches are appearing on their lawns. The problem can be their best friend as the damage to the lawn is caused by the urea within the dog’s urine. Dog urine contains a large amount of urea. When your dog urinates on your lawn it has such a strong concentrated level of nitrogen, that your grass will be destroyed leaving ugly patches of dead grass. You can dilute the urine but this has to be done soon after your dog has urinated, by pouring a bucket or two of water over the area. This may not be practical so keep your lawn moist by regular irrigation and this will help to dilute the urine. Read more about Dogs and Lawns here.

What are Chafer Grubs?


Chafer Grubs (Phyllopertha horticola and Hopia philanthus) are the larvae of the Chafer Beetle or commonly known May bug. The larvae are fairly easy to identify, their bodies are white in colour and curved like the letter C. There are 2 main types, the Welsh Chafer has a brown head and the Common Chafer has a reddish head. Both have 3 pairs of legs at the top of their body – not exactly the kind of treat you want to find in your garden, making pest prevention key to keeping your garden happy.

Towards the end of May adult beetles emerge from the soil. They will then lay their eggs into lawns and other grassed areas. After about two weeks the larvae will hatch and start to feed on the lawns’ root system. They will move deeper into the soil over the winter period and then the serious damage starts to take effect during the Spring and Summer months.

A disaster waiting to happen for your lawn!Chafer Grubs can destroy your lawn


An infestation of Chafer Grubs can be recognised by the increase of birds and wild animals using your lawn as a feeding ground, causing damage to your lawn’s surface.

What damage will be caused to my lawn?

The most serious damage is caused when local wildlife, such as Badgers, foxes and hedgehogs as well as birds see your lawn as a highly nutritious and protein rich food source because of the larvae in the grass. This may continue right through the Autumn months, stopping only during the cold weather, but will restart again in the Spring time as the Grubs will move back to the surface.

To test if your lawn’s root system has been attacked by these larvae, you can simply tug at the grass and if it moves away easily from the soil you can be sure that the roots have been eaten away. Your entire lawn is in danger of being destroyed in a very short period of time.

We are seeing a substantial increase of Chafer Grub infestations in lawns due to the insecticides that were previously used to control these Grubs have been discontinued and are no longer authorised for use. A great professional lawn care company will only use licenced and up to date insecticides when treating your lawn.

Don’t underestimate the damage that can be caused by these nuisance Grubs. Typically a small lawn less than 100 metres can cost over £800.00 to repair!

What can be done to prevent my lawn being eaten?

The most effective way to prevent costly damage to your lawn is to apply a preventative treatment NOW! By the time you see the signs of infestation it is too late to prevent the initial stages of damage to your lawn and other grassed areas.

There is little or any benefit repairing and renovating any damage to your lawn until you have KILLED the larvae. As Chafer Grubs live in the soil for up to three years you can have more than one generation in the soil at any given time. Prevention is always better than cure. A great lawn care company will know how to deal with these lawn pests and will discuss the options available for you and your lawn.

When dealing with Chafer Grubs PREVENTION is always better than cure so once your lawn company has applied one Chafer Grub treatment, it will need repeat applications annually in the growing season especially if there are repeat outbreaks most common particularly in light sandy soil areas.

Don’t let Chafer Grubs eat your lawn contact us NOW and we will arrange for one of our lawn care professionals to visit your lawn and provide a FREE lawn review service. They will be able to identify any lawn pest issues you may have.
