Help with raised beds and preventing weeds/bermuda grass...

 I'm thinking of building some raised garden beds, about 12 inches deep.
   Does anyone know if that is deep enough to discourage the bermuda
grass and other weeds from creeping in?

I plan on putting down a few layers of brown paper bags and newspaper
so hopefully that will help too.   Any other suggestions on keeping the
invasive grass out of my raised beds?  (Or is it a lost cause and I
just need to get used to pulling the bermuda runners?)

 
Doesn't really matter if you get rid of one weed because there will always
be another. Always. Maybe you don't really want to garden?

 I have raised beds but mine are 24" high. I put down layers of
newspaper.  I think eight pages is enough.   Around the outside on the
ground I did spray some crabgrass killer.

300 mills should be fine to stop stuff poking through. Anything that does
make it up from ground level will take a long time and have a struggle. The
very odd weed may come through but I think it highly unlikely. More likely
you will have problems with growth coming in from the side.

 g'day ima googler,

lay newspaper down first then the medium and mulch. the newspaper can
be laid as thick as you like generally i use between say 24 sheets to
40 sheets depending on type of grass i need to control.

we my site on the building a garden page for ideas on how i do it, and
also visit the blog section of this site for pics and ideas of my
latest project:
