My front lawn is dying. I am getting big patches of dead grass. The patches are growing bigger each week. At the beginning of the season I cue the grass and run the scarifier over it. I then cut the grass weekly and I recently have ran my scarifier over it to get rid of the dead grass. I water the grass when it is dry.


Last time this happened was about 3 years ago. The whole lawn died. I scraped the dead grass off and reseeded it.

It could just be a response to your seasonal climate. Many grasses tend to die off in heat/drought but then rejuvenate with the fall rains. My Dad used to do a 'yabba-dabba-do' dance when the whole lawn was so brown he no longer had to mow. To him, it meant more time on his boat and less time on yard work.

There are diseases that kill grass.
I do not know what is available in your area but check and try treating your lawn with such a treatment.
Back when I was not sure what was doing something similar to a lawn, that was one of the things I did .
I did not cure the entire problem but did reduce the area that was a problem.

I still do not know what the whole problem was, but I did have to remove and mostly replace soil in a six by six foot area .
I cleared and put sod on a hill that is part of the same lawn and had to pull the sod and remove and replace soil in small area there also.
It simply did hold water without constant watering.

Its usually a fungus...

Here in the deep south, with heat and humidity, we have 80 or 90 percent of plant diseases....

Probably the best thing would be to get the specific problem identified, and then plant something resistant.

Of course...
There are also insects that cause similar appearance, like cinch bugs and Japanese beetles... And nematodes.

Kinda difficult to diagnose from a photo.
Here in the states, we'd take a sample to the extension office.
Not sure about your country.

I would first try to identify any sort of disease or infestation before simply blind-treating it. Perhaps dig out a small portion of the affected sod (including the root system) and bring to your County extension and/or to a local nursery. I'd start with the County, because they are not trying to 'push product' that may or may not be effective in treating whatever you have (or don't have). Good luck.

Cross posted with Stone. I didn't catch that you are in Liverpool, so replace 'County' with whatever your local government might offer in the way of agricultural assistance.

I believe it has been hot there in the UK recently? When you water the lawn, how much do you water it? Do you measure the amount that the irrigation set-up delivers so that the lawn gets roughly an inch of rain/irrigation a week? If you can take a close-up of the blades at the edge of the affected area it may help. If you belong to the RHS they offer a free diagnostic service to members (might be worth joining just for that ). Otherwise as Deb suggested it would probably be DEFRA if they have a homeowner outreach.

jimmy - when you say you are "scraping" off the grass, would it be creating almost a crusty top layer? Is it common to aerate the lawn over there? (Removing little plugs of dirt, leaving holes which allows the rain and top-dressed nutrients to penetrate the soil?).
