How stop the grass from dying?

[Trever]

This started from a small patch of yellow grass and now it is spread to a large area. It is watered everyday and fertilised and

applied weed n feed.

Hi @Trever,

So sorry for the delay in my reply.

Could you perhaps take some closeups of the grass, as that might better illustrate the issue? 

You might like to read through this helpful article: How to detect lawn problems. 

It's far better to water long and deep a few times a week than every day for shorter periods. Watering every day can lead to fungal infections, so if the grass has become soft, slimy, and is decomposing, this could be the cause. Also, it's best to water in the morning so the grass has time to dry out before the night.

I'm keen to hear more about the type of grass you have and the specific Weed'n'Feed product you've used. If you can please link me to it, I can investigate whether this could have caused the dieback.

Please let me know if you have any questions.

Mitchell
