The "cover it with newspaper" will still leave seeds from weeds.
But if you cover it with transparent builders poly ethelene (6 foot
widths)or some such material, water it well and leave the sun to cook
the area it will sterilise the seeds as well. You will need to keep it
moist so the heat will penetrate better. Leave it for a month or so and
it should kill every thing. Otherwise, removing the surface soil and
grass would do the trick with some infestation, but only minor.

Hi everyone, good to see Len and others still helping out.

My lawn has some grass and a lot of weeds, plus I'm going to level the
lawned area so need to rip up the old lawn. Is there any way of mulching
the old lawn to use in the new garden beds I'm creating or should I
pay the
money to get it removed?

I'd like to recycle if possible but don't have the time to spend the
rest of
my life removing grass and weeds from the garden beds.

Cover it in newspaper or similar and leave until it all dies off.
