Hi all

I'm a new gardner so please excuse my ignorance in all things green...

Or, (as I suspect might be the answer) do I have to keep digging and
turning the soil until I've removed all the roots.


You will never remove *all* the roots, so forget it, just take the worst
ones out. Turf won't stop weeds coming back up through, but putting the
membrane back down before turfing will help in this respect.
