Dry cracked lawn

Grass is very resilient. Wait for some rain and it will recover. Mine is similar to yours but I know it will be OK. Here in Oxfordshire rain is forecast for this coming weekend. 🤞

Beginning of May if forecast wet. Not long to wait.

It’s a bank holiday on Monday isn’t it……so rain on the way then!

Is it clay soil? Ours is and it's just as you describe in dry weather but the grass grows again very quickly after rain. There's certainly no need to replace the lawn!

Thanks all I don't want to wish for rain but it would help I'm sure. The ground is sandy on top but clay also in places and I'm sure builders rubble as its only 5yrs old. Hopefully it will improve with ☔️🌧🌨

It might need aerating, by using a fork to make holes, top dress with compost and then feeding.
You can hire spiked rollers to make the holes.

J52 I did go over it with a fork when it was still wet I tried compost too but it was just blown all over the place as it’s also very windy here a lot of the time I had some eco friendly moss killer it’s North facing and mossy on one side. I don’t have much luck do I 😂

I was a bit heavy handed with Mo Bacter treatment which is meant to digest and remove moss. It is very brown in areas but I have every confidence in its recovery.
