Stone free soil for turfing

Hi all,

I'm still in the process of clearing my inherited stone and concrete garden,  ready to turf. The soil is quite stony, with hardcore and smaller stone mixed in.

I've bought an electric rotary soil sieve to help to remove stone from the soil once I've rotavated it (to a depth of 8 inches / 20cm)

My question is ... How deep should I aim to sieve to make it stone stone free from the surface? Before I lay the turf. I have about 115m2 to work with. Is a couple of inches enough, or should I aim for a deeper stone free surface? 

TIA

    You can go on forever trying to remove stones, its hard to know when to stop.

    Maybe take the sizeable ones out, the ones that would stop a spade going into the soil if it hit one, then take as many more smaller ones out as you can be bothered to. As long as the roots from the turf can get into the soil then you should be fine. The smaller ones might even help with drainage. You can also rotavate sharp sand into your soil to help with this.

    Mulch your boarders each year and you will build up a nice depth of stone free soil on top of the current level.
