Morning all this is my fist post so be gentle with me. I searched the forum but not managed to find an answer to my query.

I laid some new turn at the front of my house around 5 weeks ago. The turf was abolutely perfect I prepped the ground perfectly.

The week after laying the turf was a sunny week, I was watering it in the morning and at night and the roots were going down well after the first week.

Following that week it rained heavy all week and the grass grew rapidly. I then gave the lawn a cut on the highest setting of the mower however it still took a good chunk off as it had grown a lot without me being able to cut it.

I have gradually started lowering the cut over the last 2 weeks however the turf seems to be going thin and I think slightly yellow in places.

My last cut was last night and I raised the cut from the last time I mowed. I also gave it a good water as its been sunny. I have attached a few images but I'm afraid they aren't great.

Does anyone have any suggestions? I have read that a light fertiliser may help?
