Unable to grow lawn

Sue Cullen asked 6 years ago

We have only shale and builders’ rubble in our back garden but want to lay lawn. Would we need topsoil/clay if we want turf/sod which already has about 1″ soil backing to take?

Grass lawn needs at least 15cm, ideally 30cmm of good topsoil.

If you cannot get that without raising the lawn level too much, you will have to take out rubble and then lay top-soil. Although this is onerous, it will give the best result in the end.
