Asked this in gardening but I must look too scruffy/builderfied coz no
one answered. ;-)

I've removed the old turf and about four inches of soil filled with
(couch grass?) roots. I left it a few weeks to see what grew back and
have been digging and weeding the survivors out.
The old three sided border I want to reduce in size I've been digging
and weeding for about 18 months.
I've been sieving and digging in soil from the back garden where I've
a surplus to start making the level back up in the front as it is
obviously low in places from the above and it's general shoddy state
beforehand.

Is there anything I need to do before digging out my grass seed now
it's not so hot and how do you level the ground off properly rather
than by eye?

I'm sure there's some simple method to do it but think it's something
you learn from someone telling you how to do it?
